1. The large intestine absorbs water and electrolytes from digested food material. What waste product remains after water absorption and is eventually eliminated from the body?

• A. Chyme
• B. Bolus
• C. Glucose
• D. Feces

Correct answer: D

Rationale: The large intestine is responsible for absorbing water and electrolytes from digested food material. As the waste material moves through the large intestine, most of the water is absorbed, leaving behind waste products known as feces. Feces consist of indigestible material, bacteria, and some remaining waste products. This waste is eventually eliminated from the body through the process of defecation. Chyme refers to the semi-fluid mass of partially digested food that moves from the stomach to the small intestine. Bolus is a term used to describe a mass of chewed food ready to be swallowed. Glucose is a simple sugar that is absorbed in the small intestine and used as an energy source. Therefore, the correct answer is D: Feces.

2. Cartilage, found in joints and the ear, is a type of:

• A. Epithelial tissue
• B. Connective tissue
• C. Muscle tissue
• D. Nervous tissue

Correct answer: B

Rationale: The correct answer is B: Connective tissue. Cartilage is a tough, flexible type of connective tissue that provides support and cushioning in joints and the ear. It is made up of specialized cells called chondrocytes embedded in a gel-like matrix of collagen and proteoglycans. Epithelial tissue (A) covers and lines body surfaces, muscle tissue (C) is responsible for movement, and nervous tissue (D) transmits signals in the body. In contrast, cartilage primarily serves a structural and protective function, placing it within the category of connective tissue.

3. She notes that there is an increasing unrest of the staff due to fatigue brought about by

• A. Evaluate the overall result of the unrest
• B. Initiate a group interaction
• C. Develop a plan and implement it
• D. Identify external and internal forces.

Correct answer: C

Rationale: The correct answer is C: 'Develop a plan and implement it.' In the given scenario, the staff is experiencing unrest due to fatigue, which is a serious issue affecting their well-being and productivity. By developing a plan to address the fatigue issue and implementing it effectively, the organization can provide necessary support to the staff, improve working conditions, and enhance overall morale and performance. This proactive approach is crucial in maintaining a healthy work environment and ensuring the well-being of the staff members. Options A, B, and D do not directly address the root cause of fatigue and unrest among the staff, making them less suitable answers.

4. Muscles that work in opposition to each other, producing opposing movements, are called:

• A. Synergists
• B. Antagonists
• C. Agonists
• D. Fixators

Correct answer: B

Rationale: The correct answer is B: 'Antagonists.' Antagonistic muscles are pairs of muscles that work in opposition to each other to produce opposing movements around a joint. For example, the biceps and triceps in the arm act as antagonists - when the biceps contract to bend the elbow, the triceps relax, and vice versa. Synergists (A) are muscles that work together to create a movement, agonists (C) are primary muscles responsible for generating movement, and fixators (D) are muscles that stabilize joints to allow other movements to occur. Understanding the roles of antagonistic muscles is crucial in biomechanics and exercise science.

5. What is the term for a solution that has a lower concentration of solute compared to another solution?

• A. Saturated solution
• B. Unsaturated solution
• C. Dilute solution
• D. Concentrated solution

Correct answer: C

Rationale: A dilute solution has a lower concentration of solute compared to another solution. The other choices do not accurately describe a dilute solution.

6. 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.
