Question 4
Which of the following does NOT play a role in maintaining the health of an organism? (A) Mitosis (B) Cell death (C) Gene expression (D) Sexual reproduction
Worked Solution & Example Answer:Which of the following does NOT play a role in maintaining the health of an organism? (A) Mitosis (B) Cell death (C) Gene expression (D) Sexual reproduction - HSC - SSCE Biology - Question 4 - 2015 - Paper 1
Step 1
Identify the option that does NOT maintain health
Answer
To determine which option does not contribute to maintaining the health of an organism, let's analyze each choice:
- Mitosis (A): This process is essential for growth, repair, and maintenance of tissues in an organism, playing a vital role in health.
- Cell death (B): Also known as apoptosis, this process removes damaged or unnecessary cells, which is crucial for organism health.
- Gene expression (C): This is fundamental for cellular function and regulation, impacting overall health and development.
- Sexual reproduction (D): While important for species continuity, it does not play a direct role in maintaining the health of an individual organism.
Thus, the correct answer is (D) Sexual reproduction, as it does not directly contribute to the maintenance of health.
