1. Which hormone is produced by the pineal gland?

• A. Corticosteroid
• B. Oxytocin
• C. Prolactin
• D. Melatonin

Correct answer: D

Rationale: Melatonin is the hormone produced by the pineal gland. It plays a crucial role in regulating the sleep-wake cycle and is instrumental in maintaining the body's circadian rhythm. Melatonin production is triggered by darkness and inhibited by light, aiding in signaling the body when it is time to sleep. Corticosteroid, oxytocin, and prolactin are hormones produced by other glands in the body and are not associated with the pineal gland. Therefore, they are incorrect choices for this question.

2. Which word is used incorrectly in the following sentence? Please give the folder to whoever replies to your page.

• A. give
• B. envelope
• C. whoever
• D. replies

Correct answer: B

Rationale: The word 'envelope' is used incorrectly in the sentence. The correct word should be 'folder,' as mentioned in the original sentence. An envelope is a flat paper container for a letter or documents, while a folder is a folded cover for papers or documents. 'Give,' 'whoever,' and 'replies' are all used appropriately in the sentence, so they are not the incorrect words.

3. Why do cells need to use exocytosis?

• A. To obtain energy
• B. To defend against invaders
• C. To remove waste products
• D. To undergo division

Correct answer: C

Rationale: Cells need to use exocytosis to remove waste products from the cell. Exocytosis is a process where cells release molecules or substances outside the cell by fusing vesicles with the cell membrane. This process is crucial for maintaining cellular homeostasis by efficiently eliminating waste materials. Choices A, B, and D are incorrect because exocytosis is specifically involved in the expulsion of molecules, not for obtaining energy, defending against invaders, or cell division.

4. A marathon runner is training for her next race. On her weekly weekend run she completes 21.4 miles and burns 2276 calories. What is her rate of calories burned per mile?

• A. 106.4
• B. 105.6
• C. 107.5
• D. 109.3

Correct answer: A

Rationale: To calculate the rate of calories burned per mile, divide the total calories burned by the total miles run: 2276 ÷ 21.4 ≈ 106.4 calories per mile. The correct answer is A. Choice B, C, and D are incorrect as they do not match the correct calculation result. Therefore, they can be eliminated. It is essential to divide the total calories burned by the total miles run to determine the rate of calories burned per mile accurately.

5. Another word for ANTICIPATE is?

• A. Predict
• B. Evaluate
• C. Compare
• D. Forestall

Correct answer: A

Rationale: The correct answer is A: 'Predict.' Anticipate means to expect or foresee something happening in the future. 'Predict' is a synonym for anticipate as both involve forecasting or making an inference about a future event. 'Evaluate' means to assess or judge something, 'Compare' means to note similarities and differences, and 'Forestall' means to prevent or hinder something. These words do not have the same meaning as 'Anticipate.'
