01.05 Module Assessment — Foundations of Biology Exam

Module 01 — Foundations of Biology · quiz worth 100 pts

The one thing this quiz is testing This exam is 100 points covering 01.01 (what counts as science + variables + theory/law), 01.02 (macromolecule shapes and enzymes), and 01.03 (early Earth and which hypothesis claims what). Your 01.04 review interactive already mixed all three. Start there, then hit the mixed drill.

Three lessons, one exam

The exam is not a new topic. It is 01.01 + 01.02 + 01.03 in one sitting. If a question feels “from nowhere,” it is almost always one of those three.

Which lesson is this question from?

Read the stem first. Then pick a row. Do not mix the three lessons together in one answer.

If the stem is about…Go toThe usual trapThe move
Testable question, IV/DV, control, theory vs law 01.01 Exploring Life Calling a theory a guess, or saying theories become laws. Opinion → not science. You change it → IV. You measure it → DV. Theory explains; law describes.
Picture of a molecule, monomer, enzyme graph, denature 01.02 Chemistry of Life Calling lipids polymers. Mixing N (protein) with P (nucleic acid). Name the building block (hexagon / tails / amino acid / nucleotide), then the macromolecule. Enzymes lower activation energy.
Early atmosphere, Miller-Urey, RNA World, first cells 01.03 Earth's Early Atmosphere RNA World only as “shared genetic code” — missing RNA as a catalyst. Little oxygen, inorganics present. Organics from synthesis or meteorites. First cells = prokaryotes. RNA World has two costumes.
Shortcuts that give away the answer

Lookalike choices: oxygen vs carbon dioxide, increase vs decrease — read every word.

Hexagon or C₆H₁₂O₆ → carbohydrate. Tails → lipid. Folded chain / N → protein. Phosphate + base → nucleic acid.

“Only proteins catalyze” is wrong because of RNA World (Cech), not Miller-Urey.

Theory ≠ law. Theories never become laws.

How this exam will feel

Lesson 01.05 + how quizzes ask

You already sat two quizzes in this module. They did not look the same. 01.02 was seven items with molecule pictures and a written enzyme/fever item (you scored 22/22). 01.03 was five text questions, 4 points each, no pictures (16/20 — the miss was RNA as a catalyst). The module exam is allowed to use both of those styles plus 01.01 method questions. Your instructor’s DBA list is the official topic list — it matches the three lessons, not honors 01.02A (skip carbon-formula honors unless you are in honors).

01.01 — method questions

Lesson 01.01

Full walkthrough: 01.01 Exploring Life. For the exam you need: science vs opinion, peer-reviewed vs a paid commercial, independent / dependent / controlled variables / control group, why changing two things at once is invalid, x-axis = IV, and theory explains / law describes.

Likely on the quiz 01.04 review already asked: salt lowers water’s freezing point (from a data table), theory is an explanation, and an experiment with no control is missing the control.

01.02 — shapes and enzymes

Lesson 01.02

Full walkthrough + shape drill: 01.02 Chemistry of Life. Carbohydrates = hexagons / C,H,O / energy. Lipids = tails / not polymers / store energy. Proteins = amino acids / N / enzymes. Nucleic acids = nucleotides / P / genetic info. Enzymes lower activation energy and speed reactions; heat past about 50 °C denatures them (shape breaks, they stop).

Glucose ring — carbohydrate
Glucose ring — carbohydrate
Sugar + base + phosphate — nucleic acid
Sugar + base + phosphate — nucleic acid
With enzyme vs without — lower hill = lower activation energy
With enzyme vs without — lower hill = lower activation energy
Likely on the quiz 01.04 review: photosynthesis product = carbohydrate; lactase speeds lactose breakdown; sugar + nitrogen base + phosphate = nucleic acid.

01.03 — origin of life, two RNA costumes

Lesson 01.03

Full walkthrough: 01.03 Earth's Early Atmosphere. Early air: little/no oxygen, mostly CO₂, water vapor, nitrogen, lots of UV. First organics: made here from inorganics (Oparin/Haldane, then Miller-Urey flask) or arrived on meteorites. First cells: prokaryotes, anaerobic. RNA World: RNA can store code and catalyze. You already got “shared genetic code → self-replicating RNA.” The miss was “proteins are not the only catalysts → RNA World.”

Early Earth (low oxygen, UV) vs modern (oxygen + ozone)

RNA World — code and catalyst
RNA World — code and catalyst
Likely on the quiz If the stem says catalyst / enzymes / “only proteins” → RNA World. If it says shared genetic code → self-replicating RNA. If it says what was in the air → inorganics, little oxygen, not low UV.
