1. What is the largest muscle in the human body?
- A. Gluteus maximus (buttocks)
- B. Quadriceps femoris (thighs)
- C. Erector spinae (back)
- D. Pectoralis major (chest)
Correct answer: A
Rationale: The gluteus maximus is the largest muscle in the human body, located at the back of the hip and extending from the sacrum to the femur. It is a powerful muscle that plays a crucial role in extending the hip joint, enabling walking, running, and climbing stairs.
2. Which statement BEST summarizes the author's perspective on bioremediation for plastic pollution?
- A. It is the only viable solution to the problem and should be prioritized.
- B. It is a promising approach but requires further research and development.
- C. It is less effective than traditional methods and poses environmental risks.
- D. It is irrelevant to the problem and will not make a significant impact.
Correct answer: B
Rationale: The passage acknowledges the potential of bioremediation while highlighting the need for further research, indicating a balanced perspective.
3. What is the function of ribosomal RNA (rRNA)?
- A. Carries amino acids to the ribosomes
- B. Reads th(a) Carries amino acids to the ribosomes: This is the function of transfer RNA (tRNA), not ribosomal RNA. (b) Reads the genetic code on mRNA: This is the function of the ribosomes as a whole, not just the ribosomal RNA. (d) Controls the rate of protein synthesis: This is a more complex process involving various factors, not solely ribosomal RNA. e genetic code on mRNA
- C. Forms the structural framework of ribosomes
- D. Controls the rate of protein synthesis
Correct answer: C
Rationale: Rationale: Ribosomal RNA (rRNA) plays a crucial role in forming the structural framework of ribosomes, which are the cellular organelles responsible for protein synthesis. Ribosomes consist of both protein and rRNA components, with rRNA providing the structural support necessary for the ribosome to function properly. This structural framework allows the ribosome to interact with messenger RNA (mRNA) and transfer RNA (tRNA) during the process of translation, where the genetic information encoded in mRNA is used to assemble proteins from amino acids. Therefore, the primary function of rRNA is to contribute to the structure and function of ribosomes, rather than directly carrying amino acids, reading the genetic code, or controlling the rate of protein synthesis.
4. What is the term for a group of organisms living in the same place and interacting with each other?
- A. Ecosystem
- B. Community
- C. Population
- D. Niche
Correct answer: B
Rationale: Rationale: - A) Ecosystem refers to a biological community of interacting organisms and their physical environment. - B) Community specifically refers to a group of organisms of different species living in the same place and interacting with each other. - C) Population refers to a group of individuals of the same species living in the same area. - D) Niche refers to the role or function of an organism or species within an ecosystem. In this context, the term for a group of organisms living in the same place and interacting with each other is best described as a community because it involves multiple species interacting within a shared habitat.
5. After discussing the possible effects of the low patient satisfaction rate, the staff started to list
- A. Collaboration
- B. Majority rule
- C. Dominance
- D. Compromise
Correct answer: B
Rationale: The correct answer is B: 'Majority rule.' In this scenario, the staff is likely listing potential solutions or actions based on the opinion or agreement of the majority. Collaboration (A) involves working together towards a common goal, while Dominance (C) implies one person or group having control. Compromise (D) suggests finding a middle ground between different viewpoints. Majority rule best fits the situation where a decision or list of actions is being determined by what most people agree on, which is a common approach in group decision-making processes.
6. Which part of the neuron receives incoming signals from other neurons and conducts them toward the cell body?
- A. Axon
- B. Dendrite
- C. Synapse
- D. Myelin sheath
Correct answer: b
Rationale: The correct answer is B: Dendrite. Dendrites are the part of the neuron that receive incoming signals from other neurons and conduct them toward the cell body. They play a crucial role in communication between neurons by receiving neurotransmitters released from neighboring neurons. Axons transmit signals away from the cell body, synapses are the junctions where neurons communicate with each other, and myelin sheath is a fatty insulation that surrounds and protects axons. Therefore, in this scenario, dendrites are specifically responsible for receiving and conducting incoming signals towards the cell body.
