Answer 1

Answer:

1A)ingestion and egestion is that ingestion is the intake of food into the body whereas egestion is the elimination of wastes out of the body. Ingestion occurs through the mouth in animals. In protozoa, ingestion occurs by endocytosis.

2A)molars,premolared,canines,incisors

Incisors - Your incisors are eight teeth in the front center of your mouth (four on both bottom and top). These are typically the first adult teeth that a child will get, coming in when the child is between six and eight years old. Incisors are the teeth that you use to bite into your food.

Canines - Your canines are the next teeth that develop in your mouth. You have four of them and they are your sharpest teeth, used for tearing apart food.

Premolars - Premolars are used for tearing and crushing food. Unlike your incisors and canines, premolars have a flat biting surface. You have eight premolars in total.

Molars - Your molars are your largest teeth. Their function is similar to that of the premolars, to grind, tear, and crush food. Molars have a large flat biting surface which makes them perfect for this job.

3A)The intestinal villi are much smaller than any of the circular folds in the intestine. Villi increase the internal surface area of the intestinal walls making available a greater surface area for absorption. ... The villi are connected to the blood vessels so the circulating blood then carries these nutrients away.

4A)The process of continuously thinking about the same thoughts, which tend to be sad or dark, is called rumination.
