Chemistry

1. What is the common name for the compound CH₃COOH?

Correct answer: A

Rationale: CH₃COOH is commonly known as acetic acid. The other choices represent different organic acids.

2. Which gland in the endocrine system is responsible for the production of red blood cells?

Correct answer: C

Rationale: The correct answer is the Thymus gland (option C). The Thymus gland is responsible for the production and maturation of T-lymphocytes, a type of white blood cell involved in immune responses. Red blood cells are not produced by any endocrine gland; instead, they are produced in the bone marrow. The Pituitary gland (option A) secretes hormones that control various body functions, the Thyroid gland (option B) regulates metabolism, and the Parathyroid gland (option D) regulates calcium levels in the blood. Therefore, the Thymus gland is not responsible for the production of red blood cells, making it the correct answer in this case.

3. Which part of the brainstem controls heart rate and breathing?

Correct answer: B

Rationale: The correct answer is B: Pons. The pons is a part of the brainstem located above the medulla oblongata and plays a crucial role in controlling vital functions such as heart rate and breathing. It contains neural circuits that regulate the rhythmic patterns of breathing and works in coordination with the medulla oblongata to ensure proper respiratory function. While the medulla oblongata is also involved in regulating these functions, the pons is more specifically responsible for fine-tuning and coordinating the activity of these essential processes.

4. Which sentence avoids a dangling modifier?

Correct answer: C

Rationale: Option C places the participle phrase "Reading the book" in front of the subject "I," eliminating the dangling modifier.

5. What is the formula to calculate kinetic energy?

Correct answer: a

Rationale: Kinetic energy is calculated using the formula KE = ½ × mass × velocity².

6. Which of the following is NOT a function of the nervous system?

Correct answer: C

Rationale: The correct answer is C: 'Producing insulin.' The nervous system is responsible for detecting touch (option A), regulating body temperature (option B), and controlling muscle movement (option D). Insulin production is actually regulated by the endocrine system, specifically the pancreas. Insulin helps regulate blood sugar levels, which is not a function of the nervous system. It is important to differentiate between the roles of the nervous system and the endocrine system in maintaining bodily functions.
