Which of the following physiological responses is caused by the release of antidiuretic hormone?

A. Decrease in the concentration of calcium in the glomerulus

B. Increase in water reabsorption in the collecting duct

C. Increase in the concentration of calcium in the glomerulus

D. Decrease in water reabsorption in the collecting duct

Answer Explanation:

Anti-diuretic hormone (ADH) is a hormone that regulates the amount of water in the body. It is produced by the hypothalamus and released by the posterior pituitary gland. ADH acts on the kidneys to increase the reabsorption of water from the filtrate back into the blood. This reduces the volume and increases the concentration of urine.

Therefore, the Correct Answer is B.

Q #1: Nitrogen gas is an extremely stable molecule because its structure contains which of the following?

A. lonic bonds

B. Triple covalent bonds

C. Resonance bonds

D. Hydrogen bonds

Answer Explanation

Triple covalent bonds. Nitrogen gas consists of two nitrogen atoms that share three pairs of electrons, forming a triple bond. This bond is very strong and requires a lot of energy to break. Ionic bonds, resonance bonds, and hydrogen bonds are weaker types of bonds that do not occur in nitrogen gas.
Q #2: Which of the following microorganisms lack their own metabolic pathways and can only reproduce inside of a host cell?

A. Viruses

B. Bacteria

C. Helminths

D. Protozoa

Answer Explanation

Among the four types of microorganisms listed, only viruses lack their own metabolic pathways and can only reproduce inside of a host cell. Viruses are considered to be obligate intracellular parasites, meaning that they depend on another living cell for their survival and replication. Bacteria, helminths, and protozoa, on the other hand, are able to metabolize nutrients and energy from their surroundings and can reproduce independently of a host cell.
Q #3: Which of the following can lead to a tsunami?

A. Lightning strikes

B. Flooding

C. Earthquakes

D. Sunspot activity

Answer Explanation

A tsunami is a series of large waves that are caused by the displacement of a large volume of water in the ocean or a large lake. The most common cause of tsunamis is earthquakes, which can generate seismic waves that travel through the water and create sudden changes in water level.
