a. no gametes are required.
b. fewer offspring are produced.
c. it is an energy efficient way to produce offspring.
d. a shorter time is needed to produce the offspring.

1. complete the t - chart for sexual reproduction showing its advantages and

disadvantages.
sexual reproduction

Explanation:

• Question 8: Sexual reproduction involves the combination of genetic material from two parents. This recombination leads to new genetic combinations in offspring, which is genetic diversity. Clones (option C) are produced in asexual reproduction. Susceptibility to disease (option B) is not a promotion of sexual reproduction. Having the same features (option D) is also not a result of sexual reproduction as offspring have a mix of traits.
• Question 9: Looking for a mate (I) takes time. While looking, the organism can be exposed to predators (II). Also, competition for a mate (III) can lead to injury or death. All three statements (I, II, III) explain the disadvantages of finding a mate for sexual reproduction.
• Question 10: In sexual reproduction, gametes (reproductive cells) are required (so option A is wrong). It is not more energy - efficient (option C is wrong) as it involves processes like mate - finding, gamete production, etc. It also usually takes more time (option D is wrong) compared to some asexual reproduction methods. Fewer offspring are produced in sexual reproduction compared to asexual reproduction in many cases.

Answer:

• 8. A. genetic diversity
• 9. D. I, II, and III
• 10. B. Fewer offspring are produced
