<span>D is the correct answer. Metabolism is formed of two processes, anabolism, which builds new structures, for example, proteins, and catabolism, which breaks down existing structures. Catabolism breaks down large molecules like lipids into smaller ones like fatty acids.</span>
Testosterone is an example of an androgen.
Testosterone belongs to a class of male hormones called androgens, which are sometimes called steroids or anabolic steroids. IN men, testosterone is mainly produced in the testes. In women's bodies, testosterone is produced in the ovaries, adrenal glands, fat cells, and skin cells.
Testosterone products come in different forms, including gels, injectable solutions, patches, pills and pellets implanted under the skin.

Genes, otherwise known as DNA is located inside of a cell nucleus. And... theres no telling where it comes from.
If you want a complete protein in one food, tofu is probably your best bet. However, since you're probably not going to want to eat that every day, the best thing to do is eat a variety of high protein foods. Mix your proteins in order to get complete proteins. So, have say a grain (quinoa, millet, or brain rice are good) and have it with beans, or tempeh, or seitan, or nuts, etc. If you search for specific foods on that site, it'll show you which of the amino acids that food contains, and let you search for foods with complementary proteins. So if you want to be extra sure you're getting enough complete proteins, check what you're eating to see the amino acids in all of the different foods.
