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.

Therefore, the Correct Answer is B.

Q #1: Which of the following chemicals is released by one type of immune cell to directly activate another type of immune cell?

A. Lysozymes

B. Perforin

C. Cytokines

D. Granzymes

Answer Explanation

Cytokines are small proteins that act as chemical messengers between different types of immune cells. They can stimulate or inhibit the activation, proliferation, differentiation, and migration of immune cells. For example, interleukins are a type of cytokine that is produced by one type of white blood cell and can affect the behavior of another type of white blood cell. Lysozymes, perforin, and granzymes are all molecules that are involved in killing pathogens or infected cells, but they do not directly activate other immune cells.
Q #2: Which of the following best describes the result of using a catalyst in a chemical reaction?

A. The reaction is completed in a shorter amount of time.

B. The yield of product is increased.

C. A greater amount of heat energy is released by the reaction.

D. A more desirable product is often formed.

Answer Explanation

A catalyst is a substance that lowers the activation energy of a chemical reaction, which means that it allows the reaction to proceed faster without being consumed or changed itself. A catalyst does not affect the equilibrium of a reaction, so it does not change the amount or the type of product that is formed.
Q #3: Which of the following properties of water explains its solvent abilities for certain substances?

A. Polarity of water molecules

B. High specific heat

C. High surface tension

D. Kinetic energy of liquid water molecules

Answer Explanation

Water is a versatile solvent because it can dissolve many different kinds of substances. The reason for this is the polarity of water molecules, which means that they have a slight positive charge on one end and a slight negative charge on the other. This allows water molecules to attract and surround ions or polar molecules of other substances, forming hydration shells that separate them from each other.
