Correct Answer: B. by the frequency of the press releases of pressure groups

Correct Answer: D) Protein

Explanation

Pepsin is an enzyme that helps to digest a certain type of nutrient. The question is asking which nutrient this is. The options are starch, sugar, lipid, fat, and protein. To answer this question, we need to know what pepsin does and what nutrients it is responsible for breaking down. Pepsin is an enzyme that is produced in the stomach and helps to break down proteins into smaller molecules called peptides. Peptides are then further broken down into amino acids, which can be absorbed by the body and used to build new proteins. Therefore, the correct option is E: protein. It is important to note that other enzymes are responsible for breaking down other nutrients, such as amylase for starch, lipase for lipids, and sucrase for sugar. Each nutrient requires a specific enzyme to break it down properly. In summary, pepsin is an enzyme that helps to digest proteins into smaller molecules called peptides. Therefore, the correct option is D: protein. To learn more about enzymes and nutrient digestion, please read the relevant sections of the recommended textbooks

Correct Answer: A) output may be increased by changing all factors by the same proportion

Explanation

In this Economics question, we are being asked to identify which statement is not applicable in the short run. The options given are Option A: output may be increased by changing all factors by the same proportion, Option B: diminishing returns, Option C: there are sunk costs, and Option D: the total cost curve is the same as the total variable cost curve.

The correct answer is Option A: output may be increased by changing all factors by the same proportion. This statement is not applicable in the short run because in the short run, at least one factor of production is fixed, which means it cannot be changed. Therefore, output cannot be increased by changing all factors by the same proportion.

Diminishing returns, Option B, is applicable in the short run. This refers to the fact that as more of a variable input is added to a fixed input, the marginal product of the variable input will eventually decrease.

Option C, sunk costs, is also applicable in the short run. Sunk costs are costs that have already been incurred and cannot be recovered, regardless of the decision that is made.

Option D, the total cost curve being the same as the total variable cost curve, is applicable in the short run. This is because in the short run, at least one factor of production is fixed and therefore the total cost curve cannot be the same as the total variable cost curve.

In summary, the statement that is not applicable in the short run is Option A, and this is because at least one factor of production is fixed in the short run and therefore output cannot be increased by changing all factors by the same proportion.

Correct Answer: B. sensitive
