1. How many daughter cells are formed from one parent cell during meiosis?

A. One
B. Two
C. Three
D. Four

Correct answer: D

Rationale: During meiosis, one parent cell produces four genetically distinct daughter cells. This occurs through two rounds of cell division, resulting in four haploid cells with half the number of chromosomes as the parent cell. Each daughter cell is genetically unique due to processes like crossing over and independent assortment during meiosis. Choice A is incorrect because meiosis results in multiple daughter cells. Choice B is incorrect because meiosis yields more daughter cells. Choice C is incorrect because meiosis produces four, not three, daughter cells.

2. Which of the following sentences correctly uses apostrophes?

A. Our home's roof needs repairing.
B. My grandparents' families are coming to town for the holidays.
C. There are many parks located across the country.
D. All of the women's things were lost at sea.

Correct answer: A

Rationale: Choice A, 'Our home's roof needs repairing,' is the correct answer as it correctly uses the apostrophe to indicate possession. In this sentence, the apostrophe is used to show that the roof belongs to the home. Choice B is incorrect because it should be 'My grandparents' families' to show that multiple families belong to the grandparents. Choice C is incorrect as the sentence should be 'There are many parks located across the country' without using an apostrophe. Choice D is incorrect because it should be 'All of the women's things' to indicate possession by the women.

3. Which of the following is NOT a risk factor for developing atherosclerosis?

A. High blood pressure
B. High levels of LDL cholesterol
C. Regular physical activity
D. Smoking

Correct answer: C

Rationale: Regular physical activity is not a risk factor for developing atherosclerosis; in fact, it is associated with a reduced risk. High blood pressure, high levels of LDL cholesterol, and smoking are all known risk factors for atherosclerosis. Regular physical activity plays a crucial role in improving cardiovascular health, reducing the risk of atherosclerosis, and maintaining overall well-being. Therefore, the correct answer is regular physical activity (choice C).

4. Why is an extensive network of blood vessels necessary to supply the endocrine glands?

A. To filter waste from the blood
B. Because the glands empty directly into the blood
C. To allow blood to empty into the endocrine system
D. To filter waste from the endocrine glands

Correct answer: B

Rationale: The correct answer is B. Endocrine glands release hormones directly into the blood, which is why they require a rich blood supply to ensure effective hormone distribution throughout the body. The extensive network of blood vessels allows hormones to be quickly transported to target tissues and organs, regulating various physiological functions. Choices A, C, and D are incorrect because endocrine glands do not filter waste from the blood or the glands themselves. They release hormones into the bloodstream to regulate bodily functions, making a direct connection to the blood supply crucial for their function.

5. How many feet are in a mile?

A. 1,000 ft
B. 5,280 ft
C. 2,000 ft
D. 10,000 ft

Correct answer: B

Rationale: The correct answer is B: 5,280 feet in a mile. This is a standard conversion used in the Imperial system of measurement. Choice A, 1,000 ft, is incorrect as it is a common misconception and not the accurate conversion. Choice C, 2,000 ft, is also incorrect. Choice D, 10,000 ft, is significantly higher than the actual conversion and is incorrect. Remember, when converting miles to feet, the accurate value is 5,280 feet in a mile.
