What's the most common type of mutation observed in living populations, and what impact does it have on natural selection?

Biology
1 answer:
katovenus [111]3 years ago
5 0

The most common type of observed mutation is a neutral mutation. This mutation doesn't impact natural selection in any noticeable way since it doesn't impact the fit of that organism. Since neutral mutations convey no advantage, they generally must spread in a population through drift. Many also will disappear through drift.

avanturin [10]

Answer:

It will enable gut enzymes to act on the bolus during digestion.

Explanation:

The acidic presence of HCl (hydrochloric acid) in the gastric juice serves as a stimulus for the intestinal wall to produce secretin.

This hormone will act on the pancreas by stimulating the production of pancreatic juice that will contain <u>enzymes</u> (trypsinogen, amylase, lipases) and <u>HCO3⁻</u> (bicarbonate) salts, which have base composition.

With this composition that will be sent to the duodenum, there will be neutralization of acidic solution coming from the stomach and pH leveling around 8.0 (slightly basic) which is great for the enzymes that work there.
