Different types of cells reach different sizes. In general the reasons for cell size limits are due to the mechanisms needed for cell survival and how cells requirements are met by the structures that form and are contained within cells.

Nastasia [14]

Answer:

Non-migratory animals and small herbivores

Explanation:

Habitat fragmentation is the process by which a previously continuous stretch of land becomes fragmented into smaller patches that are separated, causing the environment to be broken up, and to become discontinuous. For example, humans chopping down patches of trees in forests.

Animals that cannot freely move around (non-migratory mammals) will be most affected by this since they cannot simply move between the isolated pieces of land. Smaller herbivores will also be affected, because they generally do not freely move around and cover large spaces like large herbivores or predators.

Enzymatic breakdown of which of the following compounds doesn’t begin until it reaches the stomach?
ahrayia [7]

Answer:

B. Proteins

Explanation:

Salivary amylase is an enzyme that starts the breakdown of starch in the mouth. Gastric glands of the stomach secrete gastric juice, which contains HCl to kill bacteria and denatures proteins, intrinsic factors, and the enzyme pepsin. The chief cells of gastric glands secrete pepsinogen (an inactive form of pepsin).

Pepsin begins the digestion of proteins in the stomach. It breaks down certain peptide bonds between amino acids and thereby, breaks down protein chain into smaller peptide fragments. Pepsin requires a very acidic environment of the stomach (pH 2) and becomes inactive at a higher pH.

Which of the following processes releases energy to be used by a cell?
eduard

Answer:

A

Explanation:

These three phosphate groups are linked to one another by two high-energy bonds called phosphoanhydride bonds. When one phosphate group is removed by breaking a phosphoanhydride bond in a process called hydrolysis, energy is released, and ATP is converted to adenosine diphosphate (ADP).
