In which scenario would mitosis be least desirable in terms of a species' survival? 1. a species has little energy to devote to reproduction 2. a species is unable to travel far to find a mate 3. a species has to adjust rapidly to a changing environment 4. a species is preyed upon by numerous successful predators

The correct answer will be option-3.

Explanation:

Mitosis is a type of cell division which produces daughter cells with exact or same genetic material.   The mitosis provides a better chance of survival of a species to spread any area through the asexual mode of reproduction as it produces the clones in short duration of time.

But the mitosis provides very fewer chances of survival to the species where the species has to adjust very rapidly in the changing environment as the adaptations do not become established in a population through meiosis and the favored adaptations will not be passed on to the offspring and species will become endangered.

Thus, option-3 is the correct answer.

Sperm must be deposited and transported to the site of fertilization. Ovulation must occur and the egg must be "picked up" by the tube. Union between the sperm and egg must result. The embryo must implant and begin to grow in the uterus.
