1. She is hopeful that her unit will make a big turnaround in the succeeding months. Which of
- A. Wonders why things are not what it used to be
- B. Finds solutions to the problems
- C. Integrate the solutions to his day-to-day activities
- D. Selects the best change strategy
Correct answer: C
Rationale: The correct answer is C: 'Integrate the solutions to his day-to-day activities.' In the given scenario, the individual is hopeful about a turnaround in their unit, indicating a desire for positive change. Option C aligns with this by suggesting that the individual is not only finding solutions to the problems (as in option B) but also integrating these solutions into their daily routines. This integration is crucial for sustained improvement and long-term success, making it the most appropriate choice among the options provided.
2. What is a lifestyle practice that can benefit the lymphatic system?
- A. Consuming a high-sugar diet
- B. Maintaining a sedentary lifestyle
- C. Regularly engaging in moderate exercise
- D. Smoking cigarettes
Correct answer: C
Rationale: The correct answer is C: Regularly engaging in moderate exercise. Exercise can benefit the lymphatic system by promoting circulation and the movement of lymph fluid throughout the body. This helps to remove toxins and waste products, improving overall lymphatic function. Consuming a high-sugar diet (A) can have a negative impact on the lymphatic system by increasing inflammation and impairing immune function. Maintaining a sedentary lifestyle (B) can lead to poor lymphatic circulation and fluid retention. Smoking cigarettes (D) is harmful to the lymphatic system and overall health, as it can impair immune function and increase inflammation.
3. Which of the following is NOT a type of asexual reproduction in bacteria?
- A. Binary fission
- B. Conjugation
- C. Budding
- D. Transduction
Correct answer: D
Rationale: Rationale: A) Binary fission: This is a common method of asexual reproduction in bacteria where a single cell divides into two identical daughter cells. B) Conjugation: This is a process in which genetic material is transferred between bacterial cells through direct cell-to-cell contact, leading to genetic recombination. C) Budding: Budding is a form of asexual reproduction where a new organism develops from an outgrowth or bud on the parent organism. D) Transduction: Transduction is a method of horizontal gene transfer in bacteria where genetic material is transferred from one bacterium to another by a bacteriophage (a virus that infects bacteria). It is not a form of asexual reproduction in bacteria. Therefore, the correct answer is D) Transduction, as it is not a type of asexual reproduction in bacteria but a mechanism of genetic exchange.
4. During vigorous exercise, the respiratory rate increases to:
- A. Meet the increased demand for oxygen in working muscles
- B. Eliminate excess carbon dioxide more slowly
- C. Conserve energy for physical activity
- D. Decrease the amount of oxygen delivered to the body
Correct answer: A
Rationale: During vigorous exercise, the respiratory rate increases to meet the increased demand for oxygen in working muscles. When we exercise vigorously, our muscles require more oxygen to produce energy through aerobic metabolism. Increasing the respiratory rate allows more oxygen to be taken in and transported to the muscles via the bloodstream to support this increased demand. Option A is correct because it accurately reflects the physiological response of the respiratory system to vigorous exercise, ensuring that working muscles receive sufficient oxygen for optimal performance.
5. Myelin sheath, a fatty substance, insulates nerve fibers. What type of tissue is the myelin sheath derived from?
- A. Epithelial tissue
- B. Muscle tissue
- C. Nervous tissue (glial cells)
- D. Connective tissue
Correct answer: C
Rationale: The myelin sheath is derived from nervous tissue, specifically from glial cells, which are non-neuronal cells that support and protect neurons in the nervous system. Glial cells, such as Schwann cells in the peripheral nervous system and oligodendrocytes in the central nervous system, produce the myelin sheath to insulate nerve fibers and enhance the speed of nerve impulse conduction. Epithelial tissue forms the protective covering of internal and external surfaces, muscle tissue is responsible for movement, and connective tissue provides support and structure to the body. Therefore, the correct answer is C: Nervous tissue (glial cells).
6. When you get a goosebump, which type of muscle tissue is responsible for causing the hair follicles to stand on end?
- A. Skeletal muscle
- B. Smooth muscle
- C. Cardiac muscle
- D. None of the above
Correct answer: B
Rationale: When you get a goosebump, the type of muscle tissue responsible for causing the hair follicles to stand on end is smooth muscle. Smooth muscle is found in the skin attached to hair follicles and is controlled by the autonomic nervous system. When stimulated by factors like cold or emotional responses, the smooth muscle contracts, causing the hair to stand up and creating goosebumps. Skeletal muscle (choice A) is responsible for voluntary movements, cardiac muscle (choice C) is found in the heart and is responsible for pumping blood, and none of the above (choice D) is incorrect as smooth muscle is the correct answer in this case.
