1. Convert 0.75 kilograms to grams.

• A. 75 grams
• B. 750 grams
• C. 7,500 grams
• D. 75,000 grams

Correct answer: B

Rationale: To convert kilograms to grams, you need to multiply by 1000 since there are 1000 grams in a kilogram. Therefore, 0.75 kilograms is equal to 0.75 x 1000 = 750 grams. Choices A, C, and D are incorrect as they incorrectly place the decimal point and do not reflect the correct conversion from kilograms to grams.

2. Which of the following is the main organ responsible for regulating sleep?

• A. Thalamus
• B. Hypothalamus
• C. Pituitary gland
• D. Pineal gland

Correct answer: B

Rationale: The main organ responsible for regulating sleep is the hypothalamus. The hypothalamus plays a crucial role in controlling the body's circadian rhythm, which is the internal clock that regulates the sleep-wake cycle. It receives input from the eyes about light and darkness, aiding in determining when it's time to sleep or wake up. Additionally, the hypothalamus regulates the production of melatonin by the pineal gland, a hormone that helps control sleep patterns. While the thalamus relays sensory information to the brain, the pituitary gland is primarily responsible for hormone production and release, and the pineal gland produces melatonin under the control of the hypothalamus. Therefore, the hypothalamus is the correct choice as the main organ involved in sleep regulation.

3. What is the area of a rectangle with a length of 5 cm and a width of 4 cm?

• A. 9 cm²
• B. 20 cm²
• C. 10 cm²
• D. 25 cm²

Correct answer: B

Rationale: To find the area of a rectangle, you multiply its length by its width. In this case, the length is 5 cm and the width is 4 cm. So, Area = length * width = 5 cm * 4 cm = 20 cm². Therefore, the correct answer is 20 cm². Choice A (9 cm²), Choice C (10 cm²), and Choice D (25 cm²) are incorrect as they do not result from the correct calculation of multiplying the length and width of the rectangle.

4. It can be inferred from the advertisement that

• A. A person staffing this position may work independently and/or as part of a team.
• B. Veronica Davis will make the hiring decisions.
• C. Caseloads will start out small for new hires.
• D. A candidate could work part-time if he or she chooses to.

Correct answer: A

Rationale: It can be inferred from the advertisement that a person staffing this position may work independently and/or as part of a team. The job description mentions the requirement for the ability to work both self-directed and as part of a team, indicating flexibility in working styles. Choice B is incorrect as Veronica Smith is mentioned as the contact for application submission, not the hiring decision-maker. Choice C is incorrect as there is no mention of caseload sizes for new hires. Choice D is incorrect as the advertisement does not specify part-time work as an option.

5. What is the function of the cell membrane?

• A. To protect the cell and control what enters and exits
• B. To store energy
• C. To produce proteins
• D. To synthesize lipids

Correct answer: A

Rationale: The cell membrane, also known as the plasma membrane, serves as a protective barrier for the cell, separating the internal environment of the cell from the external environment. It is selectively permeable, meaning it controls the passage of substances in and out of the cell. This regulation of what enters and exits the cell is crucial for maintaining the cell's internal environment and ensuring proper functioning. Options B, C, and D are incorrect because storing energy, producing proteins, and synthesizing lipids are functions carried out by other cellular structures such as mitochondria, ribosomes, and endoplasmic reticulum, respectively, not the cell membrane.
