Question 1 of 5

Which of the following is an example of the location and function of cartilage in the body?

A. The dense connective tissue that makes up the majority of the structural skeleton B. The supportive pads that provide cushioning at joints, such as between the vertebrae of the spinal cord C. The connective structure made of fibrous collagen that connects muscles and bones D. The layer beneath the skin and on the outside of internal organs that provides cushioning and protection

Correct Answer: B

Rationale: Cartilage is a type of flexible connective tissue that acts as supportive pads providing cushioning at joints, like those found between the vertebrae of the spine. This specific function of cartilage helps in reducing friction and absorbing shock in these areas, contributing to joint flexibility and protection.

Choices A, C, and D do not accurately describe the function and location of cartilage in the body. Option A incorrectly refers to dense connective tissue, which is different from cartilage. Option C describes tendons or ligaments, which are not cartilage. Option D refers to adipose tissue, which is a type of connective tissue that stores fat and provides insulation, but it is not cartilage.

Question 2 of 5

What type of molecules are enzymes?

A. Water molecules B. Protein molecules C. Tripolar molecules D. Inorganic molecules

Correct Answer: B

Rationale: The correct answer is B: Protein molecules. Enzymes are biological catalysts made up of proteins. They function by facilitating and speeding up chemical reactions in living organisms.
Therefore, enzymes are primarily composed of protein molecules, not water, tripolar, or inorganic molecules.
Choice A (Water molecules),
Choice C (Tripolar molecules), and
Choice D (Inorganic molecules) are incorrect because enzymes are specifically classified as proteins due to their structure and function in biological systems.

Question 3 of 5

Two nursing students will be completing a scientific experiment measuring the mass of chewed gum after one-minute chewing increments. Which lab equipment will the students most likely use?

A. Triple beam balance B. Anemometer C. Hot plate D. Microscope

Correct Answer: A

Rationale: The correct answer is A: Triple beam balance. A triple beam balance is the most suitable lab equipment for measuring mass accurately, which is necessary for this experiment. An anemometer measures wind speed, a hot plate is used for heating substances, and a microscope is used for magnifying objects, none of which are relevant to measuring the mass of chewed gum.

Question 4 of 5

Which of the following best describes one of the roles of RNA?

A. Manufacturing the proteins needed from DNA B. Creating the bonds between the elements that make up DNA C. Sending messages about the correct sequence of proteins in DNA D. Forming the identifiable double helix shape of DNA

Correct Answer: C

Rationale: The correct answer is C. RNA serves as a messenger that carries instructions from DNA for protein synthesis. It does not manufacture proteins directly from DNA (choice
A), create bonds within DNA (choice
B), or form the double helix structure of DNA (choice
D).
Therefore, the primary role of RNA is to convey information about the correct sequence of proteins to be synthesized based on the DNA sequences it receives.

Question 5 of 5

Which of the following components of the human integumentary system is the deepest?

A. Stratum basale B. Epidermis C. Hypodermis D. Dermis

Correct Answer: C

Rationale: The hypodermis is the deepest layer of the integumentary system, located below the dermis. It serves as a layer of fat that helps insulate the body, store energy, and provide cushioning. The stratum basale is the deepest layer of the epidermis, not the entire integumentary system. The epidermis is the outermost layer of the skin, followed by the dermis, and then the hypodermis.
Therefore, the correct answer is the hypodermis (choice
C).

Choices A, B, and D are incorrect as they do not represent the deepest layer of the integumentary system.
