Enzymes are made of strings of amino acids chemically bonded to one another. These bonds give each enzyme a unique structure, which determines its function. They mostly break down carbohydrates and fats. Once a protein source reaches your stomach, hydrochloric acid and enzymes called proteases break it down into smaller chains of amino acids. Amino acids are joined together by peptides, which are broken by proteases.
When the rocks are removed from a desert's ecosystem, the animals that depend on those rocks for homes would be in trouble. If these animals died due to predators and a lack of homes, then the other animals (predators) that depend on them for food would start to need other sources of food. This would cut into another predator's food supply and so on.

Answer:
Traits like white eye color in fruit flies are linked to the X chromosome.
Why:
Thomas Hunt Morgan was a scientist, he worked with Drosohilla and studied the sex chromosomes in fruit flies. In the course of his study he discovered that the white eye colour is recessive compared to the dominant red eye colour in the flies and that the white eye color gene is linked to the X sex chromosomes.
Answer:
Spores
Explanation:
Spores are small structures produced in large quantities by bacteria (as well as fungi and plants), capable of generating a new individual.
Bacterial spores (or endospores) act as survival structures when bacteria are found in unfavorable environmental conditions.
They are produced by the bacteria themselves and are found freely inside of them. The position where the spores are found is used as a way of identifying the species of bacteria.
While in the form of spores (which can be viable even for centuries for some species), the bacteria are resistant to heat, dehydration, radiation and pH variations.
When the environmental conditions are <u>favorable</u>, the spore absorbs water until it swells and breaks. From there, germination occurs, producing a cell identical to the parental cell, reactivating the metabolism, as well as the multiplication and growth of new bacteria.
