The process that makes it possible for major organs of the body to be formed by 10th week of human development is differentiation.
<u>Explanation:</u>
Human development is started off by the process of fertilization in which the sperm and ovum fuse to form zygote. In human beings fertilization takes place in the oviduct of the female. The zygote that is formed undergoes mitosis to form the embryo.
The embryo then gets embedded in the uterine walls. It continues dividing and differentiating into several organs. Almost all of the organs are formed by tenth week of pregnancy even though they aren’t fully developed.
The embryo has three layers namely ectoderm, mesoderm and endoderm. Ectoderm develops into outermost skin layer, central and peripheral nervous system, eyes and inner ears. Baby’s heart and circulatory system is formed from the mesoderm and the baby’s lungs and intestine develop from the innermost layer called endoderm.

Answer:
liver and muscles
Explanation:
Energy is actually stored in your liver and muscle cells and readily available as glycogen. We know this as carbohydrate energy. When carbohydrate energy is needed, glycogen is converted into glucose for use by the muscle cells. Another source of fuel for the body is protein, but is rarely a significant source of fuel.
