Biology
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 process by which an organism adapts to its environment through inherited traits is known as
- A. Acclimatization
- B. Behavioral ecology
- C. Natural selection
- D. Niche partitioning
Correct answer: C
Rationale: Rationale: A) Acclimatization refers to the short-term physiological adjustments an individual organism makes in response to changes in its environment. This process is reversible and does not involve inherited traits. B) Behavioral ecology is the study of how behavior contributes to an organism's survival and reproduction in its environment. While behavior can be influenced by natural selection, it is not the process by which an organism adapts through inherited traits. C) Natural selection is the process by which organisms with advantageous traits for their environment are more likely to survive, reproduce, and pass on those traits to their offspring. Over time, this leads to the adaptation of populations to their environments. D) Niche partitioning is the process by which species divide resources to reduce competition within an ecosystem. While this can influence the evolution of species, it is not the process by which an organism adapts through inherited traits.
3. She decides to illustrate the organizational structure. Which of the following elements is
- A. Level of authority
- B. Lines of communication
- C. Span of control
- D. Unity of direction
Correct answer: D
Rationale: The correct answer is D, 'Unity of direction.' In the context of illustrating organizational structure, unity of direction refers to the concept that activities within an organization should be directed towards a common goal. It ensures that all efforts are aligned and coordinated towards achieving the organization's objectives. This element helps in avoiding conflicts and confusion by providing clarity and focus on the overall mission of the organization, which is essential for effective organizational performance. Level of authority, lines of communication, and span of control are important elements in organizational structure as well, but in this scenario, unity of direction specifically pertains to the coordination and alignment of activities towards a common purpose.
4. Which of the following is NOT a characteristic of a chemical reaction?
- A. Formation of new substances
- B. Release or absorption of energy
- C. Change in color
- D. Change in temperature
Correct answer: C
Rationale: While color change can be an indicator of a chemical reaction, it's not always present, and some reactions occur without a visible color change.
5. Which preposition best completes the sentence: "She borrowed money _____ her friend."
