Anatomy

1. Semen, the fluid that carries sperm, is produced by a gland within the male reproductive system. Which gland is responsible for this?

Correct answer: D

Rationale: The correct answer is D: Seminal vesicles. The seminal vesicles are responsible for producing the fluid component of semen, which nourishes and protects sperm as they travel through the reproductive system. While the testes produce sperm, the scrotum is the external sac that holds the testes, and the prostate gland also contributes to semen production but does not produce the fluid itself. Understanding the roles of each gland in the male reproductive system is important for comprehending the process of sperm production and ejaculation.

2. Scientific findings are constantly evolving. This emphasizes the importance of:

Correct answer: C

Rationale: Science is a dynamic process built on continual questioning and refining of understanding. Openness to new evidence and revision of existing theories is crucial for scientific progress.

3. Vaccines work by stimulating the immune system to develop:

Correct answer: C

Rationale: The correct answer is C: 'Immunological memory to a specific pathogen.' Vaccines work by introducing a harmless form of a pathogen or a piece of it to stimulate the immune system. This exposure triggers the production of antibodies and memory cells specific to that pathogen. These memory cells 'remember' the pathogen, allowing the immune system to respond more effectively and rapidly if exposed to the actual pathogen in the future. Options A, B, and D are incorrect because vaccines do not create a physical barrier, induce a general inflammatory response, or directly cause phagocytes to engulf pathogens; instead, vaccines enhance the immune system's ability to recognize and combat specific pathogens.

4. When a car brakes to a stop, friction between the tires and the road acts as:

Correct answer: B

Rationale: Friction opposes the car's motion, acting as an unbalanced force that decelerates the car and brings it to a stop.

5. What is the process of breaking down and rebuilding bone tissue called?

Correct answer: B

Rationale: The correct answer is B: Remodeling. Remodeling is the process of breaking down and rebuilding bone tissue. This process helps maintain bone strength and structure by replacing old or damaged bone with new bone. Ossification refers to the formation of bone tissue, not the breakdown and rebuilding process. Calcification is the deposition of calcium salts in tissues, not specifically related to bone tissue remodeling. Osteoporosis is a condition characterized by a decrease in bone density, but it is not the process of breaking down and rebuilding bone tissue.

6. Repeating decimals can be expressed as fractions. Which of the following represents the decimal 0.7777... as a fraction?

Correct answer: C

Rationale: Let x equal the decimal. Set up two equations such that the digits after the decimal point are identical. 1000x = 777.7777... 10x = 7.7777... Subtracting the two equations, we have 990x = 770. Dividing both sides by 990 gives us x = 770/990, which can be simplified to 77/90.
