Answer the following question given this paragraph: Figure below shows what happens to waves near shore. As waves move into shallow water, they start to touch the bottom. The base of the waves drag and slow. Soon the waves slow down and pile up. They get steeper and unstable as the top moves faster than the base. When they reach the shore, the waves topple over and break. Q: What happens when waves reach the shore? Choices: - diffuse and recede - surge and drown - repel and attract - topple and break A:
topple and break

Answer the following question given this paragraph: Regulation of Nitrogen Wastes Nitrogen wastes are produced by the breakdown of proteins during normal metabolism. Proteins are broken down into amino acids, which in turn are deaminated by having their nitrogen groups removed. Deamination converts the amino (NH2) groups into ammonia (NH3), ammonium ion (NH4+), urea, or uric acid (Figure 25.22). Ammonia is extremely toxic, so most of it is very rapidly converted into urea in the liver. Human urinary wastes typically contain primarily urea with small amounts of ammonium and very little uric acid. Q: Nitrogen wastes are produced by the breakdown of what during normal metabolism? Choices: - enzymes - hormones - lipids - proteins A:
(Answer)
proteins

Ques:Answer the following question given this paragraph: Passive transport is a way that small molecules or ions move across the cell membrane without input of energy by the cell. The three main kinds of passive transport are diffusion, osmosis, and facilitated diffusion.
