Which of the following anatomical structures is directly involved in the production of hormones?

A. Pituitary ,Pancreas

B. Penis,Pons

C. Pancreas ,Penis

D. Prostate, Pancreas

Answer Explanation:

The pituitary and the pancreas are both structures of the endocrine system that produce hormones involved in body regulation, growth reaand development, sexual functioning, and other processes. The penis Is a structure of the reproductive system that responds to hormones, but it does not produce them. The prostate plays a role in converting testosterone (produced in the testicles) into dihydrotestosterone, but does not actively produce hormones. The pons is located in the brain stem and relays nerve signals that coordinate messages between the brain and the body. The pericardium is a structural component of the cardiovascular system.

Therefore, the Correct Answer is A.

Q #1: Which of the following is exchanged between two or more atoms that undergo ionic bonding?

A. Neutrons

B. Transitory electrons

C. Valence electrons

D. Electrical charges

Answer Explanation

An ionic bond forms when one atom donates an electron from its outer shell, called a valence electron, to another atom to form two oppositely charged atoms.
Q #2: Which of the following statements concerning the states of matter is NOT true?

A. Plasmas are high-temperature collections of ions and free electrons.

B. Solids are the least compressible due to the more rigid positions of the particles.

C. Gases have no definite volume and expand to fill their containers

D. Liquids have no definite shape and no definite volume.

Answer Explanation

Liquids have no definite shape, but they do have a definite volume. While the particles of liquids move more freely than those in solids, they do maintain a definite volume.
Q #3: Which of the following is an example of a chemical change?

A. Releasing compressed gas to make a bottle-rocket launch

B. Adding water to clay to make slip

C. Crystalizing honey to make candy

D. Including baking soda in a recipe to make it less sour

Answer Explanation

A chemical change involves a chemical reaction and new substances are produced. When baking soda is added to something sour (acidic) it neutralizes the acid and forms new molecules, in this case carbon dioxide and water. A physical change does not produce new substances. Phase changes such as evaporation and sublimation are physical changes. Changing the ratio of ingredients in a mixture, like adding more water to clay, does not change it chemically, but it can change some of the mixture's physical properties.
