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.

Therefore, the Correct Answer is B.

Q #1: 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.
Q #2: Which of the following indicates the function of sodium bicarbonate released by the pancreas?

A. Sodium bicarbonate inhibits peristalsis.

B. Sodium bicarbonate stimulates the pyloric sphincter.

C. Sodium bicarbonate is a protease that digests carbohydrates.

D. Sodium bicarbonate neutralizes the acidity of chyme.

Answer Explanation

The pancreas releases sodium bicarbonate into the duodenum, the first part of the small intestine. The main function of sodium bicarbonate is to neutralize the acidity of chyme, the semi-digested food that comes from the stomach. By doing so, sodium bicarbonate creates a more alkaline environment that is suitable for the action of pancreatic enzymes. Sodium bicarbonate does not affect peristalsis, the rhythmic contraction of the intestinal muscles, nor does it stimulate the pyloric sphincter, the valve that controls the passage of food from the stomach to the duodenum. Sodium bicarbonate is not a protease, an enzyme that digests proteins, nor does it digest carbohydrates.
Q #3: Testosterone is categorized as which of the following types of hormones?

A. Progestin

B. Androgen

C. Aldosterone

D. Estrogen

Answer Explanation

Testosterone is a hormone that belongs to the class of androgens, which are responsible for the development and maintenance of male characteristics. Androgens are synthesized from cholesterol and can be converted into other types of hormones, such as estrogens and progestins. Aldosterone is a different type of hormone that regulates the balance of salt and water in the body.
