  1. The deep sea is dark, cold, and under immense pressure, yet it hosts many life forms.
  2. Organisms near these vents rely on chemosynthetic bacteria rather than sunlight for energy.
  3. Some creatures produce their own light through chemical reactions, a process called bioluminescence.
  4. Hydrothermal vents release superheated, mineral-rich water that supports entire ecosystems.

Question 49
Medium
  1. Vaccines prepare the immune system to fight a disease without causing the illness itself.
  2. Booster doses are sometimes needed because immune memory can fade over time.
  3. A vaccine presents harmless fragments of a pathogen, or a weakened or inactivated form of it.
  4. Such protection has helped eliminate smallpox and bring polio close to eradication.
  5. The immune system then produces antibodies and memory cells that recognise the real pathogen later.
  6. Vaccination remains one of the most effective tools in public health.
A SPRQ
B QSPR
C RQPS
D PRSQ
Correct Answer: B

Explanation:

Q describes how a vaccine presents the pathogen, S describes the immune memory it creates, P describes booster doses, and R describes the large-scale results.
Question 50
Medium
  1. Pearls form when an irritant lodges inside the soft tissue of a mollusc.
  2. Over months or years, these layers build up into a smooth, lustrous gem.
  3. The animal responds by coating the irritant with layers of nacre, the material that lines its shell.
  4. Cultured pearls are produced by inserting a nucleus deliberately to speed up this process.
  5. Natural pearls are rare, so most pearls sold today come from farms.
  6. Their glow comes from the thin, overlapping layers that reflect light.
A RSPQ
B QPRS
C SRQP
D PRSQ
Correct Answer: B

Explanation:

Q describes the animal's coating response, P explains how the layers build up, R introduces cultured pearls, and S explains why most pearls are now farmed.
