True

False

4.

In normal blood the pH is 7.35-7.45, the partial pressure of carbon dioxide is 35-45 mm Hg, and the bicarbonate ion concentration is 22-26 mEq/L.

Select one:

A. respiratory alkalosis

B. metabolic alkalosis

C. metabolic acidosis

D. respiratory acidosis

5.

1) Production of the first polar body
2) Sperm entry
3) Mitosis of the oogonium
4) Completion of meiosis
5) Primary oocyte stalls in meiosis I
6) Ovulation

Select one:

A. 3, 5, 1, 6, 4, 2

B. 3, 5, 1, 4, 6, 2

C. 5, 1, 4, 6, 2, 3

Answer 1

1.

If an adult man sustained an injury to the anterior pituitary resulting in decreased secretion of luteinizing hormone (LH), one would expect that he would have decreased testosterone secretion.

B. decreased testosterone secretion

2.

Bile digests fat

TRUE.

Bile secreted by the liver and stored in the gall bladder helps in the breakdown of fat to produce fatty acids.

3.

B lymphocytes directly target and kill our body cells that have become cancerous.

False

B lymphocytes do not target directly, It inhibits the growth of tumors by the production of tumor-reactive antibodies and by Natural killer cells.

4.

In normal blood the pH is 7.35-7.45, the partial pressure of carbon dioxide is 35-45 mm Hg, and the bicarbonate ion concentration is 22-26 mEq/L. If a patient has a blood pH of 7.5, partial pressure of carbon dioxide of 47 mm Hg, and a bicarbonate ion concentration of 34 mEq/L, Then it is a Metabolic alkalosis.

B. metabolic alkalosis

Its because pH is in an alkaline range that is above 7.45. and it is caused by bicarbonate because bicarbonate is also in the alkaline range, which is above 26 mEq/L.

Bicarbonate represents the metabolic part so, it is metabolic alkalosis.
