Which of the following results from the incomplete breakdown of glucose that occurs under anaerobic conditions?

A. An increased pulse is a later symptom of dehydration, as the body attempts to maintain blood pressure and circulation when fluid levels are low.

B. Poor skin turgor is a sign of more advanced dehydration and is usually detected when skin remains tented after being pinched.

C. Decreased urinary output typically occurs as dehydration progresses and the body conserves water, but it is not usually the first sign.

D. Thirst is one of the earliest and most common symptoms of dehydration, as the body signals the need for water intake to restore fluid balance. This is the correct answer.

A. The diaphysis is the shaft of a long bone, the central part that extends between the two epiphyses (ends). It is primarily composed of compact bone and houses the bone marrow.

B. The periosteum is a dense layer of connective tissue that covers the outer surface of bones, except at the joints. It does not represent the shaft of the bone.

C. The cortex refers to the outer layer of the bone, specifically the compact bone that surrounds the spongy bone in the diaphysis. It is not synonymous with the shaft.

D. Osteoid is the organic matrix of bone tissue, composed of collagen and other proteins, but it does not refer to the shaft of a bone.
