A human is a complex organism that develops from a zygote. Briefly explain some of the the steps in this development process in the form of a paragraph. In your answer, be sure to: 1) explain how a zygote formed, 2) compare the genetic content of the zygote to the body cells of the parents, 3) identify the structure in which embryonic/fetal development usually occurs within, and 4) identify the structure that forms, which provides nourishment and waste removal to/from the developing baby.
