Chemistry

1. What is the formula for calculating molarity?

Correct answer: a

Rationale: All of these choices are equivalent to the original formula. The symbol "n" represents the number of moles of solute, and the symbol "V" represents the volume of the solution in liters. The symbol "L" is an abbreviation for "liters," and "dm³" is an alternative way to represent liters.

2. Certain medications can suppress the immune system to treat autoimmune diseases or prevent organ rejection after transplants. What is a potential risk associated with immunosuppressive drugs?

Correct answer: C

Rationale: The correct answer is C: 'Both a and b.' Immunocompromised individuals, who take immunosuppressive drugs, are at an increased risk of developing allergies due to the altered immune response. Additionally, these drugs suppress the immune system's ability to fight off infections, making individuals more susceptible to various pathogens. Therefore, both increased risk of developing allergies and increased susceptibility to infections are potential risks associated with immunosuppressive drugs, making option C the correct choice.

3. Percent Increase/Decrease: A medication dosage is increased by 20%. If the original dosage was 100mg, what is the new dosage?

Correct answer: C

Rationale: Multiply the original dosage (100mg) by 1 + the percentage increase (20% = 0.2) to get 120mg.

4. Which verb tense best fits the blank: "By next month, she _____ the project for a year."

Correct answer: C

Rationale: The sentence emphasizes the completed duration of the project by next month, requiring the present perfect continuous tense.

5. When sodium hydroxide (NaOH) reacts with hydrochloric acid (HCl), the resulting product is:

Correct answer: A

Rationale: This is a classic neutralization reaction, forming water and a salt (sodium chloride).

6. Which part of the brain plays a crucial role in the regulation of balance, coordination, and posture?

Correct answer: c

Rationale: The correct answer is the cerebellum (Option C). The cerebellum is responsible for the regulation of balance, coordination, and posture in the body. It receives information from sensory systems, the spinal cord, and other parts of the brain to coordinate voluntary movements. The thalamus (Option A) is involved in relaying sensory and motor signals to the cerebral cortex, but not specifically in balance and coordination. The cerebrum (Option B) is the largest part of the brain and is responsible for higher brain functions such as thinking and problem-solving. The hypothalamus (Option D) plays a role in regulating basic functions like hunger, thirst, and body temperature, but not balance, coordination, and posture. Therefore, the cerebellum is the key area of the brain involved in these specific functions.
