1. Which sentence uses the correlative conjunction "either/or" correctly?

• A. You can either come to the party or stay home.
• B. Either she will go to the concert, or he will.
• C. I'm not sure whether I should go swimming or running.
• D. He likes both pizza and pasta, so he can have either.

Correct answer: A

Rationale: Option Aa uses "either/or" to present two exclusive options.

2. What figure of speech is used in the statement "His words were a dagger to my heart"?

• A. Metonymy
• B. Simile
• C. Metaphor (Correct)
• D. Hyperbole

Correct answer: C

Rationale: The statement compares the pain of his words to a physical object, forming a metaphor.

3. Which hormone, produced by the adrenal glands, is essential for the regulation of electrolyte balance, particularly sodium and potassium, in the body?

• A. Aldosterone
• B. Epinephrine
• C. Cortisol
• D. Insulin

Correct answer: A

Rationale: The correct answer is A: Aldosterone. Aldosterone is a hormone produced by the adrenal glands that plays a crucial role in regulating electrolyte balance, especially sodium and potassium levels in the body. It acts on the kidneys to increase the reabsorption of sodium and excretion of potassium, which helps to maintain proper fluid balance and blood pressure. Epinephrine (B) is involved in the 'fight or flight' response, cortisol (C) is a stress hormone, and insulin (D) regulates blood sugar levels, but neither of these hormones primarily regulates electrolyte balance like aldosterone does.

4. Which of the following hormones is produced by the adrenal medulla and prepares the body for a stressful situation?

• A. Testosterone
• B. Cortisol
• C. Epinephrine (adrenaline)
• D. Growth hormone

Correct answer: C

Rationale: The correct answer is C: Epinephrine (adrenaline). Epinephrine is produced by the adrenal medulla and is responsible for preparing the body for a stressful situation, often referred to as the 'fight or flight' response. Testosterone is a hormone produced by the testes in males and in smaller amounts by the ovaries in females, responsible for male sexual characteristics. Cortisol is produced by the adrenal cortex and plays a role in regulating metabolism and immune response. Growth hormone is produced by the pituitary gland and is essential for growth, cell repair, and metabolism. Therefore, epinephrine is the hormone specifically produced by the adrenal medulla to prepare the body for stress.

5. Describe the ethical considerations surrounding the potential use of CRISPR-Cas9 technology in humans.

• A. Concerns about unintended consequences on the genome and potential off-target effects.
• B. Debates on modifying the human germline and potential eugenic implications.
• C. Accessibility and affordability of the technology, ensuring equitable access to benefits.
• D. Risks associated with CRISPR-Cas9 editing germline cells and potential long-term impacts.

Correct answer: B

Rationale: CRISPR-Cas9's ability to precisely edit germline cells raises ethical dilemmas about modifying the human gene pool. This includes concerns about eugenics, unintended consequences, and the long-term impact on future generations.

6. The electrical conductivity of a strong acid solution is higher than that of a weak acid solution because:

• A. Strong acids are more concentrated.
• B. Strong acids release more hydrogen ions
• C. Weak acids are better at dissolving salts.
• D. Strong acids have a lower pH.

Correct answer: B

Rationale: Strong acids completely dissociate, leading to a h
