Question

explain why a human zygote is more likely to grow into an adult than a frog zygote

Answer 1

Human zygote has more chances of survival and developing into an adult than that of frog. This is because in human the fertilisation and development into an offspring is internal and thus protecting the zygote and developing embryo from predators while the fertilisation in frog is external and thus making the zygote vulnerable to predation as they become easily accessible for predators.
