English Grammar

1. Identify the subject in the following sentence: "The red car parked in the driveway."

Correct answer: C

Rationale: The subject is the noun or pronoun performing the action or being described in the sentence.

2. Which hormone, produced by the pituitary gland, stimulates the production of milk in mammary glands during breastfeeding?

Correct answer: c

Rationale: The correct answer is C: Prolactin. Prolactin is the hormone produced by the pituitary gland that stimulates the production of milk in the mammary glands during breastfeeding. It plays a crucial role in lactation by promoting the growth and development of the mammary glands and initiating the production of milk. Growth hormone (GH) regulates growth and metabolism, not milk production. Thyroid-stimulating hormone (TSH) stimulates the thyroid gland, not mammary glands. Follicle-stimulating hormone (FSH) is involved in reproductive processes, not milk production. Therefore, prolactin is the hormone directly responsible for stimulating milk production during breastfeeding.

3. What is the primary function of the myelin sheath that surrounds some axons in the nervous system?

Correct answer: c

Rationale: The primary function of the myelin sheath that surrounds some axons in the nervous system is to speed up the transmission of nerve impulses. The myelin sheath acts as an insulating layer, which helps nerve impulses travel faster along the axon by allowing them to 'jump' from one node of Ranvier to the next, a process known as saltatory conduction. This increases the efficiency and speed of signal transmission, enabling rapid communication within the nervous system. Therefore, option C is the correct answer as it accurately describes the role of the myelin sheath in enhancing the speed of nerve impulse transmission.

4. In meiosis, how many divisions occur, and how many daughter cells are produced?

Correct answer: B

Rationale: Rationale: In meiosis, there are two divisions: meiosis I and meiosis II. During meiosis I, homologous chromosomes separate, resulting in two daughter cells with half the number of chromosomes as the parent cell. In meiosis II, sister chromatids separate, resulting in a total of four daughter cells, each with a haploid set of chromosomes. Therefore, meiosis involves two divisions and produces four daughter cells.

5. What is the characteristic property of acids?

Correct answer: b

Rationale: Acids typically have a sour taste. The other choices do not accurately describe the characteristic properties of acids.

6. Which division of the peripheral nervous system is responsible for transmitting signals from the central nervous system to skeletal muscles, enabling voluntary muscle movements?

Correct answer: a

Rationale: The correct answer is A: Somatic nervous system. The somatic nervous system is responsible for transmitting signals from the central nervous system to skeletal muscles, allowing for voluntary muscle movements. This division controls conscious movements such as walking, talking, and picking up objects. The autonomic nervous system (option B) controls involuntary functions like heart rate and digestion, while the sympathetic (option C) and parasympathetic (option D) nervous systems are subcategories of the autonomic system and regulate the body's responses to stress and relaxation, respectively. Therefore, the somatic nervous system is the correct division responsible for voluntary muscle movements.
