1. Which of the following is NOT a function of the lymphatic system?

Correct answer: B

Rationale: The correct answer is B. Releasing hormones is not a function of the lymphatic system. The lymphatic system plays crucial roles in removing substances from the blood, combating disease through the production of immune cells, and maintaining tissue fluid balance by circulating lymph. Releasing hormones is primarily the function of endocrine glands, not the lymphatic system.

2. What phenomenon occurs when light passes through a medium without changing direction, such as when passing through a window?

Correct answer: D

Rationale: The correct answer is 'Transmission.' Transmission refers to the phenomenon where light passes through a medium without changing direction, as observed when light passes through a window. Diffraction involves the bending of light waves around obstacles, reflection is the bouncing back of light waves from a surface, and dispersion is the separation of light into its different colors. In this case, the question specifically asks about the situation where light passes through a medium without changing direction, which aligns with the process of transmission.

3. An atom has 17 protons, 20 neutrons, and 17 electrons. What is its mass, in amu?

Correct answer: C

Rationale: The atomic mass of an atom is the sum of the protons and neutrons in its nucleus. In this case, the atom has 17 protons and 20 neutrons, totaling 37 particles in the nucleus. Electrons are not considered in the atomic mass calculation as their mass is negligible compared to protons and neutrons. Therefore, the mass of the atom in atomic mass units (amu) is 37.

4. What is the function of the pituitary gland?

Correct answer: A

Rationale: The correct answer is A: Produces hormones that regulate growth and metabolism. The pituitary gland is often referred to as the 'master gland' because it produces and releases hormones that regulate various bodily functions, including growth, metabolism, reproduction, and stress response. It does not filter blood or remove waste products (option B), store and release bile (option C), or produce red blood cells (option D). The pituitary gland's primary role is in hormone production and regulation, influencing many essential functions in the body.

5. "I would like to go with you; however, I won’t have time." In this sentence, what part of speech is the word "however"?

Correct answer: C

Rationale: The word "however" in the given sentence functions as a conjunctive adverb. Conjunctive adverbs are used to connect clauses or sentences and show relationships between them. In this case, "however" introduces a contrast between the speaker's desire to go and the lack of time, indicating a shift in the information provided.
