1. Variation in a population results from what
reproduction.

sexual reproduction

The process of sexual reproduction introduces variation into the species because the alleles that the mother and the father carry are mixed together in the offspring. A disadvantage is that sexual reproduction takes longer than asexual reproduction.

hey there!

so, when you eat, your teeth chew and grind food into smaller pieces. this is mechanical digestion. then reactions aided by digestive enzymes break down large food molecules into smaller molecules. this is chemical digestion. the two processes change the food into simpler substances that can be used by the body for raw materials and energy.

hope this

tobey

cuz some people don't have enough food. that's why we need more ppl to donate food to the hungry.
