1. What ethical considerations are associated with 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: The correct answer is B. CRISPR-Cas9 technology allows precise editing of germline cells, raising ethical concerns about modifying the human gene pool. This includes potential eugenic implications, debates on altering future generations, and the moral implications of such genetic modifications. Choice A discusses unintended consequences and off-target effects, but the primary ethical consideration with CRISPR-Cas9 technology relates to altering the human germline. Choices C and D, while important factors, are not the central ethical dilemmas associated with using CRISPR-Cas9 technology in humans.

2. How many milliliters are in 2 liters?

• A. 2000 mL
• B. 20,000 mL
• C. 200 mL
• D. 2 mL

Correct answer: A

Rationale: There are 1000 milliliters in 1 liter, so 2 liters equal 2000 milliliters. The conversion is based on the fact that the prefix 'milli-' means one-thousandth. Therefore, the correct answer is 2000 mL. Choice B, 20,000 mL, is incorrect as it multiplies 2 liters by 10. Choice C, 200 mL, is incorrect as it divides 2 liters by 10. Choice D, 2 mL, is incorrect as it incorrectly assumes that 2 liters is equal to 2 milliliters.

3. Which sentence uses the word 'literally' correctly?

• A. I literally died laughing at that joke.
• B. He literally climbed a mountain of paperwork.
• C. Her eyes were literally sparkling with excitement.
• D. The house was literally haunted by ghosts.

Correct answer: B

Rationale: The correct answer is B because it uses 'literally' to emphasize the magnitude of work, not to exaggerate a simple action. In this sentence, 'literally' is used to convey the idea that the person climbed a significant amount of paperwork, highlighting the challenging and overwhelming nature of the task. Choices A, C, and D use 'literally' inappropriately by exaggerating or using the word in a non-literal sense. In choice A, 'died laughing' is a common expression and not meant to be taken literally. Choice C describes a figurative expression, not a literal one. Choice D involves the supernatural, which is not a literal occurrence.

4. Which of the following root words would be used in a word related to the body?

• A. corp
• B. auto
• C. man
• D. bio

Correct answer: A

Rationale: The root word 'corp' is related to the body as it comes from the Latin word 'corpus,' meaning body. Words like 'corporal' and 'corporation' are derived from this root, linking them to the body in some manner. Choices B, C, and D are incorrect. 'Auto' relates to self or automatic, 'man' pertains to human or hand, and 'bio' is associated with life or living organisms, none of which directly signify the body.

5. What is the process of converting lactic acid back into pyruvate called?

• A. Glycolysis
• B. Gluconeogenesis
• C. Cori cycle
• D. Oxidative phosphorylation

Correct answer: C

Rationale: A) Glycolysis is the process of breaking down glucose into pyruvate. B) Gluconeogenesis is the process of synthesizing glucose from non-carbohydrate sources. C) The Cori cycle is the process by which lactic acid produced by anaerobic metabolism in muscles is transported to the liver and converted back into glucose or pyruvate. D) Oxidative phosphorylation is the process by which ATP is synthesized using energy derived from the transfer of electrons in the electron transport chain.
