Did any alleles disappear from your population? if so, why? if not, why not? how does this relate to the most fit phenotype
dmitriy555 [2]
Alleles can disappear from a population through natural selection. This relates to the most fit phenotype because the breed with the desirable trait, or the most fit, will live and produce off spring. Eventually the less desirable trait and its corresponding allele will disappear after multiple generations pass. If the environment does not change alleles of non desirable traits will disappear. <span />

umka21 [38]

Answer: Glands in your stomach lining make stomach acid and enzymes that break down food. Muscles of your stomach mix the food with these digestive juices. Your pancreas makes a digestive juice that has enzymes that break down carbohydrates, fats, and proteins, along with your liver that makes a digestive juice called bile, which helps digest fats and some vitamins. The pancreas delivers the digestive juice to the small intestine through small tubes called ducts. Bacteria in your small intestine make some of the enzymes you need to digest carbohydrates. It also absorbs water with other nutrients. Bacteria in your large intestine help break down remaining nutrients and make vitamin K NIH external link. Waste products of digestion, including parts of food that are still too large, become stool.

Explanation:

Mouth. The digestive process starts in your mouth when you chew. Your salivary glands make saliva, a digestive juice, which moistens food so it moves more easily through your esophagus into your stomach. Saliva also has an enzyme that begins to break down starches in your food.
