1. 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.

2. The theory of evolution by natural selection suggests that:

• A. Organisms evolve towards perfection
• B. Traits are acquired through use and disuse
• C. Individuals with favorable traits survive and reproduce more
• D. All of the above

Correct answer: C

Rationale: Rationale: A) Organisms evolve towards perfection - This statement is incorrect. Evolution by natural selection does not suggest that organisms evolve towards perfection. Instead, it emphasizes the adaptation of organisms to their environment over time. B) Traits are acquired through use and disuse - This statement reflects Lamarck's theory of evolution, not Darwin's theory of evolution by natural selection. Lamarck proposed that organisms could acquire traits during their lifetime and pass them on to their offspring, which has been largely discredited. C) Individuals with favorable traits survive and reproduce more - This statement accurately reflects the central concept of Darwin's theory of evolution by natural selection. Individuals with traits that are advantageous in their environment are more likely to survive and reproduce, passing on those traits to future generations. D) All of the above - This option is incorrect because not all of the statements are true. Only option C a

3. In a horizontal chart, the lowest level worker is located at the

• A. Leftmost box
• B. Middle
• C. Rightmost box
• D. Bottom

Correct answer: B

Rationale: In a horizontal chart, the lowest level worker is typically positioned at the leftmost side, with higher-level workers placed to the right. This arrangement signifies hierarchy, with the top level usually being on the rightmost side. Therefore, the correct answer is B: 'Middle,' as the lowest level worker is situated towards the left of the chart, not the extreme left or right. This positioning helps visually represent the organization's structure and indicates the progression from lower to higher levels as one moves from left to right on the chart.

4. Based on the passage, the author's attitude towards online learning is likely to be

• A. Skeptical and critical, focusing solely on its limitations and negative impacts.
• B. Enthusiastic and optimistic, overlooking any potential issues and promoting its universal adoption.
• C. Cautiously pragmatic, recognizing its valuable potential while advocating for addressing its downsides.
• D. Indifferent and neutral, lacking any strong opinion on its role in education.

Correct answer: C

Rationale: The emphasis on both benefits and challenges suggests a balanced and pragmatic perspective, aligning with C.

5. What is the scientific term for the study of genes and their role in disease?

• A. Molecular biology
• B. Biochemistry
• C. Evolutionary biology
• D. Genomic medicine

Correct answer: D

Rationale: Rationale: A) Molecular biology primarily focuses on the study of biological processes at a molecular level, including the structure and function of molecules essential to life such as DNA, RNA, and proteins. While molecular biology may involve the study of genes, it is not specifically focused on their role in disease. B) Biochemistry is the branch of science that explores the chemical processes and substances that occur within living organisms. While biochemistry may involve the study of genetic material, it does not specifically focus on the role of genes in disease. C) Evolutionary biology is the study of the processes that have shaped the diversity of life on Earth over time, including how species evolve and adapt to their environments. While genetics plays a role in evolutionary biology, it is not the primary focus of this field. D) Genomic medicine is the scientific term for the study of genes and their role in disease. This field involves understanding how variations in an indi

6. Which of the following substances is an example of an acidic gas?

• A. Nitrogen (Nâ‚‚)
• B. Carbon dioxide (COâ‚‚)
• C. Sulfur dioxide (SOâ‚‚)
• D. Oxygen (Oâ‚‚)

Correct answer: C

Rationale: Sulfur dioxide is an acidic gas. The other choices are either neutral or basic gases.
