Peristalsis is a series of muscle contractions. These contractions occur in your digestive tract. Peristalsis is also seen in the tubes that connect the kidneys to the bladder.

Peristalsis is an automatic and important process. It moves:

Food through the digestive system
Urine from the kidneys into the bladder
Bile from the gallbladder into the duodenum
Peristalsis is a normal function of the body.

Answer:

Peristalsis is a series of wave-like muscle contractions that move food through the digestive tract. ... There, the food is churned into a liquid mixture called chyme that moves into the small intestine where peristalsis continues. Stretching out a piece of intestine will make it easier to see the wave-like motion

Naily [24]

Answer:

Genetic drift (sampling error)

Explanation:

According to the given information, the population under study has a small size and is more likely to be affected by genetic drift. Genetic drift refers to any chance event that leads to random changes in the allele frequencies of a population over time.

It may occur by sampling error that either makes the allele frequency 100% in the population or completely removes it from the population. Sampling error occurs quickly in the small population. The initial frequency of "blood type A" was 3/85= 0.035. Over the time period of 45 years, sampling error during gamete formation and random fertilization removed all the individuals with "blood type A" from the population and reduced its frequency to 0.
