A. Epidermis: The epidermis is the outermost layer of the skin responsible for protection but does not store fat or regulate temperature.

B. Subcutaneous (hypodermis): The subcutaneous layer (hypodermis) contains adipose (fat) tissue, which insulates the body, cushions internal structures, and stores energy.

C. Dermis: The dermis contains blood vessels, nerves, and connective tissue but does not store fat.

A. Cause blood pH to go lower than 7.35 B. Cause blood pH to become acidic C. Cause blood pH to go above 7.45 D. Cause blood pH to become alkaline E. Cause blood pH to become base

Correct Answer is ["A","B"]

Explanation

A. Cause blood pH to go lower than 7.35: When the body breaks down fats for energy, it produces ketones, which are acidic. This leads to a drop in blood pH below the normal range (7.35–7.45), a condition known as metabolic acidosis.

B. Cause blood pH to become acidic: The accumulation of ketones results in ketoacidosis, making the blood more acidic.

C. Cause blood pH to go above 7.45: A pH above 7.45 indicates alkalosis, which is not the case in diabetic ketoacidosis (DKA).

D. Cause blood pH to become alkaline: Ketones contribute to acidosis, not alkalosis.

E. Cause blood pH to become base: A base (alkaline) pH is above 7.45, which does not happen in ketoacidosis.
