1. Which organelle is responsible for breaking down macromolecules, such as proteins, carbohydrates, and lipids, into their smaller building blocks?

• A. Golgi apparatus
• B. Mitochondria
• C. Lysosomes
• D. Endoplasmic reticulum

Correct answer: C

Rationale: Rationale: Lysosomes are membrane-bound organelles containing digestive enzymes that break down macromolecules, such as proteins, carbohydrates, and lipids, into their smaller building blocks. These enzymes help in the process of intracellular digestion and recycling of cellular components. The Golgi apparatus is involved in processing and packaging proteins for secretion or for use within the cell. Mitochondria are responsible for producing energy in the form of ATP through cellular respiration. The endoplasmic reticulum is involved in protein synthesis and lipid metabolism.

2. Kathleen knows that one of her staff is experiencing burnout. Which of the following is the

• A. Advise her staff to go on vacation.
• B. Ignore her observations; it will be resolved even without intervention
• C. Remind her to show loyalty to the institution.
• D. Let the staff ventilate her feelings and ask how she can be of help.

Correct answer: C

Rationale: The correct answer is C: 'Remind her to show loyalty to the institution.' When an employee is experiencing burnout, it is important for the supervisor to address the issue with compassion and support. Reminding the staff member to show loyalty to the institution can help them feel valued and appreciated, which can contribute to their overall well-being. This response emphasizes the importance of fostering a positive work environment and promoting a sense of belonging. Options A and B do not address the root cause of burnout and may not effectively support the staff member. Option D, while encouraging communication, does not address the loyalty aspect which can be crucial in improving morale and reducing burnout.

3. Which of the following can weaken the immune system and increase susceptibility to infections?

• A. Regular exercise
• B. Balanced diet
• C. Chronic stress
• D. Adequate sleep

Correct answer: C

Rationale: Chronic stress can weaken the immune system by increasing the production of stress hormones like cortisol, which can suppress immune function over time. Prolonged stress can also lead to inflammation, making the body more vulnerable to infections. It is important to manage stress levels through relaxation techniques, exercise, and seeking support to maintain a healthy immune system.

4. Which kingdom primarily consists of multicellular, photosynthetic organisms with cell walls made of cellulose?

• A. Animalia
• B. Fungi
• C. Plantae
• D. Protista

Correct answer: C

Rationale: Rationale: A) Animalia consists of multicellular organisms that lack cell walls and are heterotrophic. B) Fungi are multicellular organisms with cell walls made of chitin and are heterotrophic. C) Plantae primarily consists of multicellular, photosynthetic organisms with cell walls made of cellulose. This description fits plants. D) Protista is a diverse kingdom that includes unicellular and multicellular organisms with varying characteristics, but it does not primarily consist of multicellular, photosynthetic organisms with cell walls made of cellulose.

5. What is the difference between exhalation (expiration) and inhalation (inspiration)?

• A. Exhalation involves active muscle contraction, while inhalation is passive.
• B. Inhalation brings in oxygen-rich air, while exhalation releases oxygen-depleted air.
• C. Exhalation occurs through the nose only, while inhalation can occur through the nose or mouth.
• D. Inhalation warms and humidifies air, while exhalation cools and dries air.

Correct answer: B

Rationale: Option B is the correct answer because inhalation is the process of breathing in, where the diaphragm and intercostal muscles contract to expand the chest cavity, allowing air to enter the lungs. This air is rich in oxygen, which is essential for cellular respiration. On the other hand, exhalation is the process of breathing out, where the diaphragm and intercostal muscles relax, causing the chest cavity to decrease in size and air to be expelled from the lungs. This air is depleted of oxygen as it has been used up during cellular respiration. Understanding the difference between inhaling oxygen-rich air and exhaling oxygen-depleted air is crucial for comprehending the respiratory system's function and the exchange of gases in the body.

6. What is the name of the master gland that regulates the function of many other endocrine glands?

• A. Thyroid gland
• B. Pituitary gland
• C. Hypothalamus
• D. Adrenal gland

Correct answer: B

Rationale: The correct answer is B: Pituitary gland. The pituitary gland is often referred to as the 'master gland' because it plays a crucial role in regulating the function of many other endocrine glands in the body. It secretes hormones that control various processes such as growth, metabolism, and reproduction. The thyroid gland (A) primarily regulates metabolism, the hypothalamus (C) helps control the pituitary gland, and the adrenal gland (D) produces hormones involved in stress response. Therefore, the pituitary gland is the main gland responsible for coordinating the activities of other endocrine glands, earning it the title of the master gland.
