which hormone causes the kidneys to reabsorb more water from forming urine and as a result, increases blood volume?
a thyroid - stimulating hormone (tsh)
b insulin
c cortisol
d antidiuretic hormone (adh)

Explanation:

• For the first question: Hematopoiesis (production of blood cells) occurs in the red bone marrow. Yellow bone marrow is mainly composed of fat cells and has limited hematopoietic activity in adults. The epiphyseal line is a remnant of the growth plate and is not involved in blood cell production. Articular cartilage covers the ends of bones in joints and has no role in hematopoiesis.
• For the second question: Antidiuretic hormone (ADH) acts on the kidneys to increase water reabsorption from the forming urine. This reduces urine volume and increases blood volume. Thyroid - stimulating hormone (TSH) stimulates the thyroid gland. Insulin is involved in glucose metabolism. Cortisol is a stress - related hormone with multiple functions like regulating metabolism and immune response, but not specifically in increasing water reabsorption in the kidneys to increase blood volume.

Answer:

A. red bone marrow
D. antidiuretic hormone (ADH)
