Sample 1 · Reproduction, growth and development

Asexual reproducing organisms exhibit little or no genetic variation because: (i) asexual reproduction does not involve gamete formation. (ii) asexual reproduction involves only one parent. (iii) in asexual reproduction no fusion of gametes is involved. (iv) during asexual reproduction many offspring are produced.

  1. If (i), (ii) and (iii) are correct.
  2. If (i) and (iii) are correct.
  3. If (ii) and (iv) are correct.
  4. If only (iv) is correct.
Sample 2 · Respiration and gas exchange
