Which of the following occurs when blood volume and pressure become too high?
The renal tubules reabsorb more water.
The kidneys produce less urine.
ADH release is inhibited.
The renal tubules reabsorb more sodium.
The Correct Answer is C
A. The renal tubules reabsorb more water. If blood volume and pressure are too high, the body would aim to reduce them, not increase them further. Reabsorbing more water would increase blood volume.
B. The kidneys produce less urine. To lower blood volume and pressure, the kidneys would increase urine production, not decrease it.
C. ADH release is inhibited: ADH (antidiuretic hormone) promotes water reabsorption in the kidneys, leading to increased blood volume and pressure. When blood volume and pressure are too high, the body inhibits ADH release to promote water excretion and lower blood volume and pressure.
D. The renal tubules reabsorb more sodium. Reabsorbing more sodium would lead to water retention, increasing blood volume and pressure, which is the opposite of what the body needs when blood volume and pressure are already high.

Correct Answer is A
Explanation
A. Small intestine; small intestine: Both amino acids and monosaccharides are absorbed in the small intestine, and fatty acids are also absorbed in the small intestine, where they are reassembled into triglycerides and incorporated into chylomicrons.
B. Small intestine; liver: Amino acids and monosaccharides are absorbed in the small intestine, but fatty acids are absorbed in the small intestine, not directly in the liver.
C. Stomach; small intestine: Amino acids and monosaccharides are absorbed in the small intestine, not the stomach, and fatty acids are absorbed in the small intestine, not the stomach.
D. Stomach; large intestine: Amino acids and monosaccharides are absorbed in the small intestine, and fatty acids are absorbed in the small intestine, not the stomach or large intestine.
Correct Answer is A
Explanation
A. Monozygotic; dizygotic: Monozygotic twins are identical twins that result from the division of a single fertilized egg. Dizygotic twins, or fraternal twins, result from the fertilization of two separate eggs.
B. Dizygotic; monozygotic: This is the reverse of the correct order. Dizygotic twins come from two eggs, and monozygotic twins come from one egg.
C. Monozygotic; identical: Monozygotic twins are identical, but this choice does not mention dizygotic twins, which makes it incomplete.
D. Dizygotic; nonidentical: While dizygotic twins are nonidentical, this choice does not properly define the types of twins produced by a single egg (monozygotic).
