Answer key with explanation!
1. C) Test cross β Used to find an unknown genotype by crossing a dominant-trait plant with a homozygous recessive plant.
2. C) Nucleotide β nucleic acids β Nucleotides are the single building blocks (monomers) that link to form
DNA/RNA (polymers).
3. D) DNA polymerases β hydrolysis of ATP β Mismatch. DNA polymerases synthesize new DNA strands; they do not break down ATP.
4. A) Pentadactyl limb modification β This is a structural feature, making it evidence for comparative anatomy, not biochemistry.
5. B) All of the above β Conservation combines ecological repair, scientific research, and keeping human intervention to a minimum.
6. B) The first product formed is a three carbon compound β The first stable molecule created during C3 carbon fixation contains three carbon atoms.
7. A) Infectious diseases β These are illnesses caused directly by invading pathogens like bacteria and viruses.
8. C) Non-competitive inhibitor β Binds to a separate spot (allosteric site) on the enzyme instead of blocking the active site directly.
9. A) Movement of water molecules across cell membrane β This process is osmosis, a type of passive transport that uses zero cellular energy (ATP).
10. D) The solution is isotonic to the cell sap of the potato tissue β An isotonic solution balances water movement perfectly, causing no net gain or loss in weight.
