If telomerase enzymes are less active than usual, what medical condition will this cause?
Correct answer: D. Premature aging
- A. Cancer
- B. Pneumonia
- C. Cardiovascular disorders
- D. Premature aging
Explanation
Reduced telomerase activity results in faster telomere shortening, leading to cellular senescence and ultimately contributing to premature aging. This is because telomerase is responsible for maintaining telomere length during cell division. In contrast, cancer is usually associated with increased telomerase activity, allowing cells to divide indefinitely. Cardiovascular disorders may be linked to telomere shortening but are not directly a consequence of decreased telomerase activity. Pneumonia is unrelated to telomerase activity as it is an infectious condition affecting the lungs.

About Scientific Reasoning
Scientific reasoning evaluates hypotheses through observations, variables, controls, measurements and experimental results. Questions involve identifying independent and dependent variables, recognising a fair test, interpreting tables or graphs, distinguishing evidence from opinion, and deciding whether data supports, rejects or leaves a hypothesis unresolved.
