1. Which of the following describes a responsibility of the integumentary system?

A. Distributing vital substances, such as nutrients, throughout the body.
B. Blocking pathogens that cause disease.
C. Sending leaked fluids from the cardiovascular system back to the blood vessels.
D. Storing bodily hormones that influence gender traits.

Correct answer: B

Rationale: The correct responsibility of the integumentary system is to act as a barrier that blocks pathogens from entering the body, thus helping to prevent diseases and infections. This function serves as the first line of defense for the body against external threats. Choices A, C, and D are incorrect. Choice A is a function of the circulatory system, not the integumentary system. Choice C relates to the lymphatic system, not the integumentary system. Choice D involves the endocrine system, not the integumentary system.

2. What is the author's point of view?

A. First person
B. Third person limited
C. Third person omniscient
D. Objective

Correct answer: B

Rationale: The passage is told from a third person limited point of view because the thoughts and perspectives of two specific characters, Michael and Lana June, are presented. The narrator provides insight into their thoughts, but remains limited to their viewpoints without revealing the thoughts of any other characters. This extract demonstrates the limited perspective by showing the inner thoughts of Michael and Lana June, indicating a third person limited narrative. Third person omniscient would involve knowing the thoughts of all characters, which is not the case here. First person would involve using 'I' to narrate, which is absent. Objective point of view would present only observable actions without any character's thoughts or feelings, which is not the case in this passage.

3. Convert 0.5 liters to milliliters.

A. 50 ml
B. 500 ml
C. 5 ml
D. 0.5 ml

Correct answer: B

Rationale: To convert liters to milliliters, you need to multiply by 1000 as there are 1000 milliliters in 1 liter. Therefore, when converting 0.5 liters to milliliters, the correct answer is 0.5 x 1000 = 500 ml. Choice A (50 ml) is incorrect because it represents the conversion of 0.05 liters, not 0.5 liters. Choice C (5 ml) is incorrect as it represents the conversion of 0.005 liters. Choice D (0.5 ml) is incorrect as it does not reflect the correct conversion from liters to milliliters.

4. What is 31% of 426?

A. 425.69
B. 132.06
C. 13.7
D. 0.07

Correct answer: B

Rationale: To find 31% of 426, multiply 0.31 by 426. This gives 0.31 Ã— 426 = 132.06. Therefore, choice B, 132.06, is the correct answer. Choice A, 425.69, is close to the original number but is not the correct answer for the percentage calculation. Choice C, 13.7, is not the correct result for 31% of 426. Choice D, 0.07, is significantly lower than the correct answer and does not represent 31% of 426.

5. How many liters are in 750 milliliters?

A. 7.5 liters
B. 0.75 liters
C. 0.0075 liters
D. 0.075 liters

Correct answer: B

Rationale: To convert milliliters to liters, you need to divide by 1000 since there are 1000 milliliters in a liter. Therefore, 750 milliliters divided by 1000 equals 0.75 liters. Choice A (7.5 liters) is incorrect as it is off by a factor of 10. Choice C (0.0075 liters) is incorrect as it is off by a factor of 100. Choice D (0.075 liters) is incorrect as it is off by a factor of 10.
