1. What conclusion can a reader draw from this passage?

• A. It is advisable to choose unsaturated fats over saturated fats.
• B. Saturated fats are more calorically dense than unsaturated fats.
• C. Trans fats are more calorically dense than saturated fats.
• D. Unsaturated fats are mostly found in animal products.

Correct answer: A

Rationale: The correct conclusion that can be drawn from the passage is that it is advisable to choose unsaturated fats over saturated fats. The passage emphasizes the health benefits of unsaturated fats, such as lowering cholesterol levels and reducing the risk of heart disease. It also mentions that saturated fats, although not as healthy as unsaturated fats, should still be consumed sparingly. Trans fats are highlighted as the least healthy fats, increasing the risk of heart disease. Choice B is incorrect because the passage does not explicitly compare the caloric density of saturated and unsaturated fats. Choice C is incorrect as the passage does not discuss the caloric density of trans fats in comparison to saturated fats. Choice D is incorrect as the passage states that unsaturated fats are found in sources like olive oil, walnut oil, and avocado oil, not mostly in animal products.

2. In which phase of mitosis do new nuclear membranes form around sets of chromosomes?

• A. Prophase
• B. Anaphase
• C. Telophase
• D. Interphase

Correct answer: C

Rationale: The correct answer is C, Telophase. During telophase, the final phase of mitosis, new nuclear membranes form around sets of chromosomes at the opposite poles of the cell. This process marks the completion of nuclear division in mitosis. Choices A, B, and D are incorrect because in prophase, chromosomes condense but nuclear membranes are not formed; in anaphase, chromosomes separate and move to opposite poles but no new nuclear membranes are formed; and in interphase, the cell prepares for division but nuclear membranes are not forming around sets of chromosomes.

3. What is another word for EXPEDITE?

• A. Transfer
• B. Rush
• C. Cancel
• D. Hold

Correct answer: B

Rationale: The correct answer is B: Rush. To expedite means to accelerate the progress or speed of something, to hasten or facilitate. 'Transfer' (choice A) means to move from one place to another, 'Cancel' (choice C) means to call off, and 'Hold' (choice D) means to keep or detain. Therefore, 'Rush' is the most appropriate synonym for expedite in this context.

4. What is the result of dividing 3.44 by 0.6?

• A. 11.41
• B. 5.73
• C. 2.33
• D. 0.57

Correct answer: B

Rationale: The correct answer is B: 5.73. When dividing 3.44 by 0.6, the calculation is 3.44 ÷ 0.6 = 5.73. Choice A (11.41) is incorrect because it is the result of multiplying, not dividing. Choice C (2.33) and Choice D (0.57) are also incorrect results obtained by incorrect calculations.

5. Which organ system is primarily responsible for maintaining temperature control?

• A. The skeletal system
• B. The digestive system
• C. The nervous system
• D. The integumentary system

Correct answer: D

Rationale: The integumentary system, which includes the skin, hair, and nails, is primarily responsible for maintaining temperature control in the body. The skin helps regulate body temperature through processes like sweating to cool down and shivering to generate heat. Additionally, blood vessels in the skin can dilate or constrict to control the amount of heat lost or retained by the body. This system plays a crucial role in maintaining homeostasis and keeping the body at a stable temperature. The skeletal system (Choice A) provides structural support and protection to the body but is not directly involved in temperature regulation. The digestive system (Choice B) is responsible for breaking down food and absorbing nutrients, not for regulating body temperature. The nervous system (Choice C) controls body functions through electrical impulses but is not the primary system responsible for temperature control.
