Question

In close comparisons, extemal fertilization often yields more offspring than internal fertilization. However,

internal fertilization offers the advantage that
a. it requires less time and energy to be devoted to reproduction
b.
the smaller number of offspring produced often receive a greater amount of parental care
and thus have a greater survival rate.
c. it requires expression of fewer genes and maximizes genetic stability,
d. it is the only way to ensure the survival of species

Answer 1

The answer is b.
Internal fertilization takes more time and energy but it allows for the offspring to revive more devoted care. When an organism spends that much time and energy investing in an offspring it becomes worth the investment to devote more care towards it.
