This is a student-facing review page. Read it, work the fresh practice (including the worked pH and surface-area-to-volume examples), and follow the dated plan. Then run the paired Exam-Prep Tutorial and take the Practice Exam for active recall. (This guide points to those two — it does not repeat them.)

Integrity note for students. Every practice item on this page is a fresh variant — a new scenario and wording — with a vetted answer. None of these are the live midterm questions. Working them builds the skill the midterm tests, the honest way.


What the midterm covers (read this first)

Exam Midterm — cumulative, Weeks 1–7, Objectives 1–4
Format 20 items, 100 points. Concept-, scenario-, and quantitative-pocket items: most items hand you a short situation and ask you to classify, identify, compute, or order — plus two quantitative pockets (a pH comparison and a surface-area-to-volume calculation). Expect a mix of multiple-choice, a few matching items (process-order and structure→function), two "select all that apply," and a couple of true/false. AI is not permitted on the midterm.
Coverage (where the points are) Obj 1 = 3 items (the process of science & life) · Obj 2 = 6 items (chemistry & macromolecules) · Obj 3 = 4 items (the cell & transport) · Obj 4 = 7 items (energy, enzymes, respiration & photosynthesis — the biggest slice). Study Objective 4 hardest, then Objective 2.
Weight The midterm is 20% of your course grade.
When it opens / where Opens in the Week 8 module (the review-and-exam week); window opens at module start and is due 6 days later; one attempt. This guide and the exam-prep tutorial post before the window so you can prepare. There is no weekly quiz, assignment, or lab in Week 8 — the midterm replaces them (Discussion 8, the midterm debrief, still runs).
What to bring A simple grasp of the two arithmetic moves (pH factors of 10; SA:V = 6/s for a cube) — no calculator gymnastics. Build the one-page concept sheet this guide helps you make (key terms, the misconception-cures, the worked pH and SA:V examples).

How to use this guide. Each objective below has the same four parts: (A) the key ideas in plain language, (B) the definitions / terms / procedures, (C) the predictable mistakes and their cures, and (D) where to review in the module. After all four objectives come fresh worked examples + self-check questions (with answers, including the quantitative pockets), a dated study plan, and how it's graded + test strategy.


Objective 1 — The Process of Science & Characteristics of Life (Week 1) · 3 items

(A) Key ideas, plain language

Biology begins with two questions: what does it mean to be alive, and how do we figure out what's true instead of what merely sounds true? Life is defined by a whole set of characteristics (no single trait works), and truth is established by the scientific method — especially a clean controlled experiment that changes one thing and compares against a baseline.

(B) Definitions, terms, procedures

  • Characteristics of life (the checklist): built from cells; use energy (metabolism); grow & develop; reproduce (pass on DNA); respond to stimuli; maintain homeostasis; and evolve (populations change over generations). A thing is alive only if it shows the whole set.
  • Levels of organization (small → large): atom → molecule → cell → tissue → organ → organ system → organism → population → community → ecosystem → biosphere. New emergent properties appear at each level.
  • The scientific method (a loop): observation → question → hypothesis → prediction → experiment → analyze data → conclusion → (new question).
  • Controlled experiment: independent variable = the one thing you change; dependent variable = what you measure; controlled variables = everything held constant; control group = the no-treatment baseline you compare against. A second difference between groups is a confounding variable.
  • Hypothesis vs. theory: a hypothesis is a single, testable, falsifiable prediction; a theory is a broad, well-supported explanation (evolution by natural selection, the cell theory, germ theory). In science, "theory" means the opposite of shaky.

(C) Predictable mistakes → cures

  • "If it moves and grows, it's alive." → ✅ Fire and crystals do too. Require the whole checklist (cells, DNA, homeostasis, evolution).
  • "A theory is just a guess." → ✅ A theory is overwhelmingly supported; the single testable prediction is the hypothesis.
  • Swaps the independent and dependent variables. → ✅ I change the Independent; the result Depends on it.
  • "The control group gets the treatment." → ✅ The control is the no-treatment baseline; the experimental group gets the treatment.

(D) Review in the module

Week 1 → Lecture Outline (the life checklist, levels of organization, the scientific method, variables, hypothesis vs. theory), Slides (Deck 1), Readings, Lecture Tutorial 1, and Lab 1 (Drops on a Penny).


Objective 2 — The Chemistry of Life & Macromolecules (Weeks 2–3) · 6 items — a big slice

(A) Key ideas, plain language

Life runs on chemistry. Atoms join by sharing or transferring electrons; water's polarity gives it the strange, life-giving behavior cells depend on; and pH measures how acidic or basic a solution is (a quantitative pocket). Then cells build four families of macromolecules from small monomers — and the theme of the whole course appears: structure determines function. This is a big slice (6 items) — know it cold.

(B) Definitions, terms, procedures

  • Bonds: covalent = atoms share electrons (strong); ionic = one atom transfers an electron, forming charged ions that attract (strong); hydrogen bond = weak attraction between a slightly + H and a slightly − atom.
  • Water (from polarity): cohesion (water-to-water → surface tension), adhesion (water-to-other → capillary climb), high specific heat (temperature buffering), ice floats (insulates lakes), universal solvent (dissolves many substances).
  • pH (each whole unit = a 10× change in [H⁺]): pH < 7 acidic, = 7 neutral, > 7 basic. Higher pH = fewer H⁺. A buffer resists (minimizes) pH change — it doesn't prevent any change. (Pre-verified: pH 4 vs pH 7 = 10³ = 1000× more acidic; pH 2 vs pH 4 = 10² = 100×; [H⁺] at pH 3 = 10⁻³ M.)
  • Macromolecules (built by dehydration synthesis = remove water; broken by hydrolysis = add water):
  • Carbohydrates — monomer monosaccharide; energy (starch) and structure (cellulose).
  • LipidsNOT polymers; energy storage, membranes (phospholipids), steroids.
  • Proteins — monomer amino acid (peptide bonds); enzymes/structure/transport; shape → function (one wrong amino acid → sickle-cell).
  • Nucleic acids — monomer nucleotide; DNA/RNA store and transmit information.

(C) Predictable mistakes → cures

  • "Ionic bonds share electrons." → ✅ Ionic = transfer; covalent = share.
  • "Higher pH = more acidic." → ✅ Higher pH = fewer H⁺ = less acidic (more basic).
  • Swaps cohesion and adhesion. → ✅ Cohesion = to itself; adhesion = to another.
  • "Lipids are polymers," or "all carbs are sugar." → ✅ Lipids aren't polymers; cellulose is structural fiber, not quick energy.
  • "Hydrolysis builds polymers." → ✅ Hydrolysis breaks (adds water); dehydration synthesis builds (removes water).

(D) Review in the module

Week 2 → Lecture Outline (atoms & bonds, water's properties, pH/acids/bases/buffers), Slides (Deck 2), Lecture Tutorial 2, Lab 2 (red-cabbage pH). Week 3 → Lecture Outline (the four macromolecules, structure→function), Slides (Deck 3), Lecture Tutorial 3, Lab 3 (macromolecule food tests).


Objective 3 — Cell Structure, Membranes & Transport (Week 4) · 4 items

(A) Key ideas, plain language

The cell is the smallest unit that is unambiguously alive. Cells come in two grand types (prokaryotic vs. eukaryotic), are built from organelles you should know by function, are wrapped in a phospholipid bilayer, and move things across that membrane by passive (no energy) or active (ATP) transport. And there's a hard size limit set by a quantitative pocket: surface-area-to-volume.

(B) Definitions, terms, procedures

  • Prokaryote vs. eukaryote: the defining difference is the nucleusprokaryotes lack a membrane-bound nucleus (DNA floats free; generally smaller), eukaryotes have one. Both have a membrane and DNA.
  • Organelles (structure → function): nucleus (stores DNA, directs the cell) · ribosome (protein synthesis) · mitochondrion (cellular respiration → ATP) · chloroplast (photosynthesis, in plants) · rough/smooth ER, Golgi, lysosome, vacuole, cell wall (support roles). Plant cells have BOTH chloroplasts and mitochondria.
  • Membrane: the phospholipid bilayer (fluid-mosaic model) is the cell's selectively permeable border.
  • Transport: passive (down the gradient, no ATP): diffusion (solutes high→low), osmosis (water down its gradient), facilitated diffusion. Active (against the gradient, needs ATP). Solutions: hypotonic (water enters the cell), hypertonic (water leaves), isotonic (no net change).
  • Surface-area-to-volume (why cells stay small): for a cube, side s: SA = 6s², V = s³, SA:V = 6/s. (Pre-verified: s=1 → 6:1; s=2 → 3:1; s=3 → 2:1; s=4 → 1.5:1.) As a cell grows, SA:V decreases → less surface per unit of volume → cells stay small (and use folds/microvilli).

(C) Predictable mistakes → cures

  • "Osmosis moves the solute." → ✅ Osmosis moves WATER down its gradient.
  • "Plant cells don't have mitochondria." → ✅ They have both chloroplasts and mitochondria.
  • Reverses hypertonic and hypotonic. → ✅ In a hypotonic solution, water enters the cell (it swells); in hypertonic, water leaves (it shrinks).
  • "A bigger cell has a higher SA:V" / "bigger cells are better." → ✅ SA:V decreases as a cell grows (6/s) — bigger is worse for exchange.

(D) Review in the module

Week 4 → Lecture Outline (prokaryote vs. eukaryote, organelles, the membrane, transport, surface-area-to-volume), Slides (Deck 4), Lecture Tutorial 4, Lab 4 (SA:V of cubes + diffusion).


Objective 4 — Energy, Enzymes, Respiration & Photosynthesis (Weeks 5–7) · 7 items — STUDY HARDEST

(A) Key ideas, plain language

Cells run on energy. ATP is the spendable currency; enzymes make reactions go fast enough to live. Then two big pathways, taught as ordered overviews (inputs → outputs, where ATP is made): cellular respiration releases energy from sugar, and photosynthesis stores energy in sugar. This is the largest slice of the exam (7 items); budget the most time here, and memorize the order and location of each stage.

(B) Definitions, terms, procedures

Energy & enzymes (Week 5):
- ATP = the cell's energy currency (cycles with ADP by gaining/losing a phosphate). Not DNA (information), not glucose (fuel).
- Enzymes = biological catalysts that lower activation energy; they are specific (lock-and-key/induced fit) and reusable (not used up). Rate rises with temperature/substrate to an optimum, then denaturation (loss of shape) makes it crash. "More heat is always better" is false.

Cellular respiration (Week 6) — order & location (overview):
- Glycolysiscytoplasm; glucose → 2 pyruvate; net 2 ATP; no O₂ (anaerobic start).
- Krebs (citric-acid) cyclemitochondrial matrix; releases CO₂; makes NADH/FADH₂.
- Electron transport chaininner mitochondrial membrane; O₂ is the final electron acceptor; makes the most ATP.
- Fermentation (no O₂): lactic-acid (muscle) or alcohol — keeps a little ATP coming. Overall: glucose + O₂ → CO₂ + H₂O + ATP.

Photosynthesis (Week 7) — order & location (overview):
- Light-dependent reactionsthylakoid membranes; split water → release O₂; make ATP + NADPH.
- Calvin cycle (light-independent)stroma; fix CO₂ into sugar using ATP + NADPH.
- The released O₂ comes from splitting water (not CO₂); a plant's mass comes mostly from CO₂ (air) + water. Photosynthesis and respiration are roughly reverse, and both run in plants.

(C) Predictable mistakes → cures

  • "Enzymes are used up in the reaction." → ✅ Enzymes are reusable catalysts.
  • "More heat always speeds an enzyme up." → ✅ Past the optimum it denatures and the rate falls.
  • Confuses ATP with DNA. → ✅ ATP = energy; DNA = information.
  • "The most ATP comes from glycolysis," or "O₂ is used in glycolysis." → ✅ The ETC makes the most ATP; O₂ is the final acceptor at the end.
  • "Respiration = breathing," or "plants don't respire." → ✅ Respiration is a cellular process; plants respire too.
  • "The photosynthetic O₂ comes from CO₂," or "the Calvin cycle doesn't need light." → ✅ O₂ comes from water; the Calvin cycle needs the light reactions' ATP/NADPH.

Representative practice (all fresh — vetted answers)

None of these are live midterm items. New scenarios, new wording. Each answer is vetted; the one-line why names the idea it tests. Cover the answers, work each one, then check. The two quantitative examples are worked in full — make them automatic.

Objective 1 practice

Worked example 1 — the life checklist + experiment design.
A student claims a growing salt crystal is alive because it "grows and has order," and wants to test whether warmer water makes crystals grow faster.
- (a) Is the crystal alive? Name two characteristics it fails. (b) Name the IV, DV, and a control group for the experiment.
Answer. (a) Not alive — it has no cells and no DNA (and no homeostasis, no metabolism). Order alone isn't enough. (b) IV = water temperature; DV = crystal size/mass after a set time; control = crystals grown at room temperature (the baseline), everything else held constant. Why: life is the whole set; the control is the no-treatment baseline.

Worked example 2 — hypothesis vs. theory.
A friend says, "Evolution is just a theory, and 'plants grow toward light' is also just a theory."
- (a) Correct the "just a theory" claim about evolution. (b) Is "this basil will grow taller in more light" a hypothesis or a theory?
Answer. (a) In science a theory is a broad, overwhelmingly supported explanation (like the cell theory) — not a hunch. (b) It's a hypothesis — a single, testable, falsifiable prediction. Why: theory = big & battle-tested; hypothesis = one tested guess.

Self-check (Obj 1).
1. True/false: a single bacterium is too simple to count as alive. → False — one cell can be a complete living organism.
2. Order these small→large: organ, atom, cell, molecule, tissue. → atom → molecule → cell → tissue → organ.
3. A second, uncontrolled difference between your two groups is called a — → confounding variable.
4. Which is measured, the IV or the DV? → The DV (the independent variable is what you change).

Objective 2 practice

Worked example 1 — the pH pocket (quantitative, worked in full).
A lab tests stomach acid at pH 2 and blood at pH 7.
- (a) How many times more H⁺ does the stomach acid have than blood? (b) Which is more acidic, and what is [H⁺] at pH 2?
Answer. (a) Difference = 5 pH units; each unit = 10×, so 10⁵ = 100,000× more H⁺. (b) The stomach acid (pH 2) is far more acidic; [H⁺] at pH 2 = 10⁻² M. Why: each pH unit is a factor of 10; lower pH = more acidic. (Re-derive: 10^(7−2) = 100,000.)

Worked example 2 — bonds, water & macromolecules.
- (a) In a water molecule the O shares electrons unequally with two H's — what bond, and what property results? (b) Is a fat (lipid) a polymer? (c) What's the monomer of a protein?
Answer. (a) Covalent bonds (sharing); the unequal sharing makes water polar, giving cohesion/adhesion/solvent power. (b) No — lipids are not polymers. (c) The amino acid. Why: covalent = share → polarity; lipids aren't polymers; proteins are amino-acid chains.

Self-check (Obj 2).
1. Most acidic of pH 3, 6, 8, 10? → pH 3 (lowest pH).
2. A solution at pH 9 has more or fewer H⁺ than pure water (pH 7)? → Fewer (it's basic).
3. Cellulose vs. starch — same monomer? → Yes, both are glucose polymers (structure vs. storage). Structure → function.
4. Hydrolysis adds or removes water to break a polymer? → Adds water.

Objective 3 practice

Worked example 1 — the SA:V pocket (quantitative, worked in full).
A biologist compares two model cells: a cube 3 units on a side and a cube 1 unit on a side.
- (a) Compute SA:V for each. (b) Which exchanges materials more efficiently, and what does this say about why cells stay small?
Answer. (a) s = 3: SA = 6(9) = 54, V = 27 → 2:1. s = 1: SA = 6, V = 1 → 6:1. (b) The smaller cube (6:1) has more surface per unit of volume, so it exchanges materials more efficiently. As a cell grows, SA:V falls, so cells stay small (or fold their membranes). Why: SA:V = 6/s; re-derive 6/3 = 2, 6/1 = 6.

Worked example 2 — cells & transport.
A red blood cell is dropped into pure water and swells.
- (a) Is the surrounding solution hypotonic or hypertonic? (b) What moves, and is ATP required? (c) Name the organelle that makes the cell's ATP.
Answer. (a) Hypotonic (more water outside). (b) Water moves into the cell by osmosisno ATP (passive). (c) The mitochondrion. Why: hypotonic → water enters; osmosis moves water passively; mitochondria make ATP.

Self-check (Obj 3).
1. The single defining difference between prokaryotes and eukaryotes? → The nucleus (prokaryotes lack a membrane-bound one).
2. True/false: plant cells have no mitochondria. → False — they have both chloroplasts and mitochondria.
3. Which cube has the highest SA:V: side 1, 2, 3, or 4? → Side 1 (6:1).
4. Active transport requires what that passive transport doesn't? → ATP (energy).

Objective 4 practice — largest section; work all of these

Worked example 1 — enzymes.
A potato slice added to hydrogen peroxide fizzes (catalase releasing O₂); a boiled potato slice does almost nothing.
- (a) Why does the boiled slice fail? (b) Are enzymes used up as they work?
Answer. (a) Boiling denatured the catalase — high heat unfolds the enzyme so its active site no longer works. (b) No — enzymes are reusable catalysts. Why: past the optimum, heat denatures; enzymes aren't consumed.

Worked example 2 — respiration order & location.
- (a) Where does glycolysis occur, and how much ATP (net) does it make? (b) Which stage makes the most ATP, and what is oxygen's role there?
Answer. (a) Cytoplasm; net 2 ATP. (b) The electron transport chain makes the most ATP, and oxygen is the final electron acceptor. Why: glycolysis (cytoplasm, 2 ATP) → Krebs (matrix) → ETC (inner membrane, most ATP, O₂ acceptor).

Worked example 3 — fermentation.
A sprinter's legs burn during a 200-meter dash.
- (a) Which process runs when O₂ is low, and what builds up? (b) Does fermentation make more or less ATP than aerobic respiration?
Answer. (a) Lactic-acid fermentation; lactic acid builds up (the burn). (b) Less ATP — fermentation is a stopgap. Why: no O₂ → fermentation → lactic acid; the ETC (which needs O₂) is where most ATP comes from.

Worked example 4 — photosynthesis.
A skeptic insists a tree's wood came from the soil.
- (a) Where does the released O₂ come from? (b) Where does most of the tree's mass come from? (c) Name the two stages and their locations.
Answer. (a) From splitting water in the light reactions. (b) Mostly from carbon in CO₂ from the air (plus water). (c) Light-dependent reactions in the thylakoids; the Calvin cycle in the stroma. Why: O₂ from water; mass from CO₂ + water; light reactions → Calvin cycle.

Self-check (Obj 4).
1. ATP or DNA — the cell's energy currency? → ATP.
2. True/false: more heat always speeds an enzyme up. → False (it denatures past the optimum).
3. Most ATP: glycolysis or the ETC? → The ETC.
4. True/false: plants do cellular respiration. → True (all the time).
5. The O₂ released in photosynthesis comes from CO₂ or water? → Water.


Study plan — a dated countdown (sized to 2 sessions/week)

Built for the Week 8 midterm. Adjust the exact dates to your section's posted exam day; the rhythm is what matters. Do a little across several days rather than one long cram (spacing beats massing — and it lines up with how memory actually works).

When Do this (≈45–75 min)
~7 days out (Week 7, after class) Read this guide's Objectives 1 & 2 sections. Work the Obj 1 & 2 practice — including the pH worked example until "each unit = 10×, pH 4 vs 7 = 1000×" is automatic. Build your one-page concept sheet (the life checklist, the IV/DV/control frame, the bond/water cures, the pH rule, the four macromolecules + monomers).
~5 days out Read Objectives 3 & 4 carefully (they are 11 of 20 items). Work the Obj 3 practice — drill the SA:V worked example (6/s; side 2 = 3:1; growing = decreasing) until it's automatic. Re-derive any you missed.
~3 days out Work all of the Obj 4 practice (enzymes, the order/location of respiration, fermentation, photosynthesis). Then run the paired Exam-Prep Tutorial (N-exam-prep-tutorial-week-08) in an approved chatbot (Gemini / Claude / ChatGPT) — it diagnoses your weak spots across the whole midterm and drills them with fresh items.
~2 days out Take the Practice Exam (the paired O-practice-exam-week-08) under timed, closed-note conditions. Score it; list every concept you missed.
~1 day out Re-teach only the topics you missed on the practice exam (use this guide's mistake-cures and the relevant Lecture Tutorial). Re-do those specific self-checks, especially any quantitative ones. Sleep — memory consolidates overnight.
Exam day Skim your one-page concept sheet (and the two arithmetic rules). Arrive early. Read each item twice and answer the question actually asked. AI is not permitted — bring your understanding.

Two paired tools — use both (don't skip):
- Exam-Prep Tutorial (N-exam-prep-tutorial-week-08) — a copy/paste chatbot tutor that diagnoses, re-teaches, and drills you across all of Objectives 1–4, ending with a readiness summary. Best for active recall and shoring up weak spots.
- Practice Exam (O-practice-exam-week-08) — a full, fresh, mirror-format run. Best for pacing and a final readiness check.

(This guide points to both on purpose — it doesn't duplicate them.)


How the midterm is graded + test-taking strategy

How it's graded.
- 100 points across 20 items, 5 points each, weighted toward application (read a scenario; classify, compute, or order) rather than bare recitation. The matching and "select all that apply" items are scored per correct pairing/selection.
- The midterm is 20% of your course grade. It replaces Week 8's quiz, assignment, and lab (the midterm-debrief Discussion 8 still runs). One attempt; AI not permitted.
- Coverage matches this guide: Obj 1 = 3 · Obj 2 = 6 · Obj 3 = 4 · Obj 4 = 7. Time is dominated by Objective 4 (energy) and Objective 2 (chemistry/macromolecules), so practice those until they're automatic.

Honest test-taking strategies for this material.
1. Translate each scenario into its concept first. Underline cue words — change / measure, share / transfer, passive / active, cytoplasm / matrix / inner membrane — then match to the term.
2. For the life checklist, demand the whole set. One trait (movement, growth) is never enough — look for cells, DNA, homeostasis.
3. Do the two arithmetic moves the same way every time. pH: count the units, raise 10 to that power; lower pH = more acidic. SA:V: for a cube it's 6/s — smaller = higher; growing = lower.
4. For macromolecules, pair each with its monomer (carbs→monosaccharides, proteins→amino acids, nucleic acids→nucleotides) and remember lipids aren't polymers — that's a favorite distractor.
5. For transport, ask "what moves and does it cost ATP?" Osmosis moves water, passively; active transport spends ATP against the gradient.
6. For respiration & photosynthesis, recite the order and location. Glycolysis (cytoplasm) → Krebs (matrix) → ETC (inner membrane, most ATP, O₂ acceptor); light reactions (thylakoid, split water → O₂) → Calvin cycle (stroma, fix CO₂).
7. Watch the classic reversals: higher pH ≠ more acidic; the ETC (not glycolysis) makes the most ATP; the O₂ comes from water (not CO₂); SA:V decreases as a cell grows.
8. Do the easy items first, flag the hard ones, and budget time — 20 items means a few minutes each. Don't sink ten minutes into one item while quick ones wait.
9. On "select all that apply," judge each option independently — the false one is usually a famous misconception (lipids are polymers; plants don't respire).
