Answer key with explanation! 1. C) Test cross — Used to find an unknown genotype by crossing a dominant-trait plant with a homozygous recessive plant. 2. C) Nucleotide – nucleic acids — Nucleotides are the single building blocks (monomers) that link to form DNA/RNA (polymers). 3. D) DNA polymerases – hydrolysis of ATP — Mismatch. DNA polymerases synthesize new DNA strands; they do not break down ATP. 4. A) Pentadactyl limb modification — This is a structural feature, making it evidence for comparative anatomy, not biochemistry. 5. B) All of the above — Conservation combines ecological repair, scientific research, and keeping human intervention to a minimum. 6. B) The first product formed is a three carbon compound — The first stable molecule created during C3 carbon fixation contains three carbon atoms. 7. A) Infectious diseases — These are illnesses caused directly by invading pathogens like bacteria and viruses. 8. C) Non-competitive inhibitor — 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 — 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 — An isotonic solution balances water movement perfectly, causing no net gain or loss in weight. @maths_group11
