Why do you think many animals reproduce sexually?

It provides genetic variation, making it a better option than asexual reproduction.

Explanation:

Sexual reproduction provides genetic variation in the offspring, while asexual reproduction doesn't. This of course facilitates natural selection.

as in mitosis, dna replication occurs during interphase.   in meiosis, it occurs specifically in s phase of interphase 1.

when you breathe in, or inhale, your diaphragm contracts (tightens) and moves downward. this increases the space in your chest cavity, into which your lungs expand. the intercostal muscles between your ribs also enlarge the chest cavity. they contract to pull your rib cage both upward and outward when you inhale.
