Answer:
The Tigris and Euphrates rivers made it possible to grow wheat on the arid Mesopotamian plains, but the dry climate eventually defeated human engineering. Irrigation brought water to fields faster than it could drain out. As salt-rich groundwater rose and surface water evaporated, mineral salts built up in the soils. Farmers switched to more salt-tolerant grains like barley, but the harder they farmed, the less they harvested. After about 2,000 years, the once-fertile land of southern Mesopotamia was barren.

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.
