1. What is the recommended daily fiber intake for adults?
- A. 10 grams
- B. 25 grams
- C. 35 grams
- D. 50 grams
Correct answer: B
Rationale: Rationale: The recommended daily fiber intake for adults is around 25 grams for women and 38 grams for men. Fiber is essential for maintaining a healthy digestive system, preventing constipation, and reducing the risk of chronic diseases such as heart disease and diabetes. Consuming an adequate amount of fiber can also help with weight management and promote overall well-being. Therefore, option B is the most appropriate answer based on the recommended daily intake guidelines for adults.
2. The Merkel cells, located in the epidermis, are specialized for:
- A. Melanin production
- B. Temperature sensation
- C. Touch perception
- D. Immune defense
Correct answer: C
Rationale: The correct answer is C: 'Touch perception.' Merkel cells, also known as Merkel discs, are found in the skin's epidermal layer and are responsible for sensing touch. These cells are located near nerve endings and help detect light touch and pressure on the skin. They play a crucial role in the perception of tactile sensations and are not involved in melanin production, temperature sensation, or immune defense. Therefore, the specialized function of Merkel cells is primarily related to touch perception, making option C the correct choice.
3. Alexandra is tasked to organize the new wing of the hospital. She was given the authority to
- A. Benevolent –authoritative
- B. Consultative
- C. Exploitive-authoritative
- D. Participative
Correct answer: D
Rationale: The correct answer is D: Participative. In a participative leadership style, Alexandra would involve the team members in decision-making and encourage their input when organizing the new wing of the hospital. This approach fosters collaboration, empowers team members, and can lead to better outcomes as everyone's perspectives are considered. Benevolent-authoritative (A) involves a leader who is kind and caring but makes decisions independently. Consultative (B) involves seeking input from team members but making the final decision independently. Exploitive-authoritative (C) involves a leader who uses their authority in a self-serving or oppressive manner. In this scenario, with the task of organizing a new wing of the hospital, a participative approach would be most effective in engaging the team and utilizing their expertise.
4. What protein complex controls the progression of mitosis through its activation and degradation?
- A. Ribosome
- B. Cyclin-dependent kinase (CDK)
- C. Centriole
- D. Microtubule
Correct answer: B
Rationale: Rationale: A) Ribosome: Ribosomes are cellular organelles responsible for protein synthesis and are not directly involved in controlling the progression of mitosis. B) Cyclin-dependent kinase (CDK): CDKs are a family of protein kinases that regulate the cell cycle, including the progression of mitosis. CDK activity is controlled by cyclins, which bind to CDKs to activate them at specific points in the cell cycle. The activation and degradation of cyclins regulate the activity of CDKs, which in turn control the progression of mitosis. C) Centriole: Centrioles are involved in organizing the microtubules of the mitotic spindle but do not directly control the progression of mitosis. D) Microtubule: Microtubules are structural components of the cytoskeleton and are involved in various cellular processes, including mitosis, but they do not control
5. A car brakes to a stop on a level road. Which of the following forces does NOT do work on the car?
- A. The braking force applied by the wheels
- B. The normal force from the road
- C. The gravitational force on the car
- D. The friction force between the tires and the road
Correct answer: B
Rationale: While the other forces do work by changing the car's motion or energy, the normal force acts perpendicular to the motion and doesn't contribute to the car's stopping.
6. When proofreading your writing, focus on:
- A. Changing the wording to sound more original.
- B. Ignoring minor grammatical errors like typos.
- C. Checking for clarity, consistency, and overall flow.
- D. Replacing common words with thesaurus alternatives.
Correct answer: C
Rationale: Proofreading involves correcting errors, refining sentence structure, and ensuring the writing achieves its purpose, clarity, and consistency.
