Chapter 39, Problem 3CCQ
Summary Introduction
To write:
Living organisms use energy and most of them reproduce sexually.
Introduction:
Reproduction may be asexual or sexual. Both have certain advantages as well as disadvantages. Asexual Reproduction provides a simpler way to the living organisms in order to produce multiple copies of itself. Sexual reproduction requires two individuals to produce offsprings. Asexual reproduction is more prevalent in species that live in extremely stable environments.

Which of the following is a disadvantage of sexual reproduction?
a.)Offspring can be reproduced more quickly than by sexual means
b.)Two parents are required for making sex cells
c.)Offspring are genetically different
d.)Genetic diversity makes organism respond uniformly to environment changes
Which factors are responsible for successful reproduction in male? Do you think the reproductive efficiency of male is declining with the passage of time? Support your point of view with examples.
A paradox of sexual reproduction is that despite its being widespread in nature, the question of why it exists at all is still unresolved. What are some disadvantages of sex? What are some consequences of sex that make it so important?
