2026-2027
Unit 1: Chemistry of Life & Cells

Q1: Cell Theory - Prokaryote vs Eukaryote
Question: Which is prokaryote?

 A) Incorrect
 B) Correct biology – correct
 C) Incorrect
 D) Incorrect

Correct Answer: B

Detailed Explained Rationale: B correct – Bacteria prokaryote no nucleus circular DNA.
Eukaryote has nucleus membrane-bound organelles. Both have ribosomes, DNA.



Q2: Enzymes
Question: Enzyme function affected by?

 A) Correct biology – correct
 B) Incorrect
 C) Incorrect
 D) Incorrect

Correct Answer: A

,Detailed Explained Rationale: A correct – Enzyme lowers activation energy, affected by
temp/pH denaturation, substrate concentration. Active site specificity lock-key/induced fit.




Unit 2: Cell Division & Genetics

Q3: Mitosis phases
Question: Mitosis order?

 A) Correct biology – correct
 B) Incorrect
 C) Incorrect
 D) Incorrect

Correct Answer: A

Detailed Explained Rationale: A correct – PMAT: Prophase chromosomes condense,
Metaphase align middle, Anaphase sister chromatids separate, Telophase nuclei form +
cytokinesis.



Q4: Mendelian - Punnett
Question: Aa x Aa cross ratio?

 A) Incorrect
 B) Correct biology – correct
 C) Incorrect
 D) Incorrect

Correct Answer: B

Detailed Explained Rationale: B correct – Aa x Aa = 1 AA:2 Aa:1 aa genotypic, 3 dominant
phenotype:1 recessive. Mendel law segregation and independent assortment.




Unit 3: DNA & Evolution

Q5: Central Dogma
Question: Central dogma flow?

 A) Correct biology – correct
 B) Incorrect

, C) Incorrect
 D) Incorrect

Correct Answer: A

Detailed Explained Rationale: A correct – DNA -> transcription -> RNA -> translation ->
protein. Reverse transcription retroviruses. Replication DNA->DNA.



Q6: Natural Selection vs Drift
Question: Genetic drift vs selection?

 A) Incorrect
 B) Correct biology – correct
 C) Incorrect
 D) Incorrect

Correct Answer: B

Detailed Explained Rationale: B correct – Selection adaptive differential reproduction,
drift random change especially small populations bottleneck/founder.




Unit 4: Ecology & Human Body

Q7: Ecology - Energy
Question: Trophic levels energy transfer?

 A) Correct biology – correct
 B) Incorrect
 C) Incorrect
 D) Incorrect

Correct Answer: A

Detailed Explained Rationale: A correct – 10% rule energy lost as heat, biomass decreases
up. Producers -> primary -> secondary -> tertiary.



Q8: Homeostasis - Negative Feedback
Question: Example negative feedback?

 A) Incorrect

,  B) Correct biology – correct
 C) Incorrect
 D) Incorrect

Correct Answer: B

Detailed Explained Rationale: B correct – Negative feedback returns to set point: insulin
lowers glucose, thermostat. Positive feedback amplifies: childbirth oxytocin, clotting.
