Answer:

Birds’ feathers are designed to be light but very strong, flexible but very tough. Although it looks like feathers grow all over a bird, they actually grow in specific areas called feather tracks. In between the feather tracks are down feathers. This keeps the body weight down.

Feathers are made of a tough and flexible material called keratin. The spine down the middle, called the shaft, is hollow. The vanes are on the two halves of the feather. They are made of thousands of branches called barbs. Because there are many spaces between these barbs, a feather has as much air as matter.

Anettt [7]

Norman ate his birthday cake with lots of sugary frosting, so his pancreas secreted insulin.

FSH (follicle stimulating hormone) stimulates the production of egg cells in women or sperm in men. A woman's PRL (prolactin) causes the corpus luteum, located in the area around mature follicles, to produce her two key hormones, estrogen, and progesterone.

Growth hormone (GH) or somatotropin, also known as the human form of human growth hormone (HGH or HGH), is a peptide hormone that stimulates growth, cell renewal, and cell regeneration in humans and other animals.

This type of hormone characteristically requires a second messenger. PTH is required to produce calcitriol (activated vitamin D), which is required for calcium transport through cells.
