• A. One substance dissolves in another
• B. Two or more substances react chemically

3. What is the difference between type 1 and type 2 diabetes, both related to insulin and blood sugar?

• A. Type 1 is caused by insulin resistance, type 2 by insulin deficiency.
• B. Type 1 is temporary, type 2 is permanent.
• C. Type 1 affects adults, type 2 affects children
• D. Type 1 is treated with diet only, type 2 requires medication.

Correct answer: A

Rationale: The correct answer is A: 'Type 1 is caused by insulin resistance, type 2 by insulin deficiency.' Type 1 diabetes is an autoimmune condition where the body attacks insulin-producing cells, leading to insulin deficiency. In contrast, type 2 diabetes occurs when the body becomes resistant to insulin's effects. This distinction is crucial for understanding the underlying causes and treatment approaches for each type of diabetes. Type 1 diabetes is not temporary; it is a chronic condition that requires lifelong management. Type 2 diabetes can also affect adults, but it is more commonly diagnosed in middle-aged and older adults. Treatment for type 1 diabetes typically involves insulin therapy along with diet and exercise, while type 2 diabetes may require medication in addition to lifestyle modifications.

4. Which of the following is NOT a function of the cardiovascular system?

• A. Transporting oxygen to cells
• B. Maintaining blood pressure
• C. Carrying waste products to the kidneys for removal
• D. Initiating the immune response

Correct answer: D

Rationale: The cardiovascular system is responsible for transporting oxygen to cells (option A), maintaining blood pressure (option B), and carrying waste products to the kidneys for removal (option C). However, initiating the immune response (option D) is not a function of the cardiovascular system. The immune response is primarily carried out by the immune system, which includes organs like the spleen and lymph nodes. While the cardiovascular system does play a role in immune function by transporting immune cells and antibodies, it is not responsible for initiating the immune response. Therefore, option D is the correct answer.

5. According to the passage, learning from history can help us

• A. predict future events with complete certainty.
• B. avoid any possibility of making mistakes in the present.
• C. identify potential challenges and develop innovative solutions.
• D. directly replicate the successes of past societies in our own time.

Correct answer: C

Rationale: The passage emphasizes learning from both successes and failures, identifying potential obstacles, and using historical knowledge to create solutions for current problems.

6. What is the recommended daily intake of protein for adults to maintain healthy muscle mass?

• A. 0.5 grams per kilogram of body weight
• B. 1 gram per kilogram of body weight
• C. 1.5 grams per kilogram of body weight
• D. 2 grams per kilogram of body weight

Correct answer: C

Rationale: The recommended daily intake of protein for adults to maintain healthy muscle mass is 1.5 grams per kilogram of body weight. Protein is essential for muscle repair and growth, and consuming an adequate amount helps support overall muscle health. 1 gram per kilogram of body weight is generally recommended for sedentary individuals, but for those looking to maintain or build muscle mass, a higher intake of 1.5 grams per kilogram of body weight is advised. Consuming too little protein can lead to muscle loss, while consuming too much may strain the kidneys. Therefore, 1.5 grams per kilogram of body weight strikes a balance for most adults looking to support their muscle health.
