1. Which neurotransmitter is associated with mood, sleep, and memory?

Correct answer: B

Rationale: The correct answer is B: Serotonin. Serotonin is a neurotransmitter that plays a crucial role in regulating mood, sleep, and memory. It is known as the 'feel-good' neurotransmitter because it helps to promote feelings of well-being and happiness. Serotonin also contributes to the regulation of sleep patterns and plays a role in memory and learning processes. Dopamine is associated with reward and motivation, acetylcholine with muscle movement and cognitive functions, and glutamate with learning and memory as an excitatory neurotransmitter. Therefore, of the options provided, serotonin is the neurotransmitter most closely linked to mood, sleep, and memory.

2. What is the main idea of the following passage: "The internet has revolutionized communication, allowing people to connect instantly from anywhere in the world. Social media platforms, like Facebook and Twitter, have further amplified this connectivity, enabling individuals to share information and ideas on a global scale."

Correct answer: C

Rationale: The passage emphasizes the transformative impact of the internet and social media on communication.

3. Which term describes the point where parallel rays of light converge or appear to diverge from after passing through a lens or reflecting off a mirror?

Correct answer: B

Rationale: The focal length is the term that describes the point where parallel rays of light converge or appear to diverge from after passing through a lens or reflecting off a mirror. It is a crucial parameter in optics and is used to determine the magnification and image formation in optical systems. The other options (A) Aperture, (C) Refractive index, and (D) Lens thickness are not directly related to the point where parallel rays converge or diverge.

4. In the female reproductive system, what structure produces eggs (ova)?

Correct answer: A

Rationale: The correct answer is B: Ovaries. The ovaries are the primary reproductive organs in the female body responsible for producing eggs (ova) through a process called ovulation. The fallopian tubes serve as the passageway for the egg to travel from the ovary to the uterus for potential fertilization. The uterus is where a fertilized egg implants and develops into a fetus during pregnancy. The vagina is the muscular canal that connects the uterus to the outside of the body and serves as the birth canal during childbirth. Therefore, the ovaries are specifically responsible for the production of eggs in the female reproductive system.

5. Stretch marks occur when

Correct answer: C

Rationale: Stretch marks occur when the dermis layer tears due to rapid stretching. During periods of rapid growth or weight gain, the skin may stretch beyond its capacity, causing the dermis layer to tear and resulting in the formation of stretch marks. Inflammation or clogged sebaceous glands do not directly cause stretch marks, making options A, B, and D incorrect. It is important to understand the physiological process behind stretch marks to identify the correct answer.

6. Which division of the nervous system is responsible for involuntary functions such as heart rate, digestion, and respiratory rate?

Correct answer: b

Rationale: The correct answer is B: Autonomic nervous system. The autonomic nervous system is responsible for regulating involuntary functions in the body, such as heart rate, digestion, respiratory rate, and other automatic processes. The somatic nervous system (A) controls voluntary muscle movements, the peripheral nervous system (C) consists of nerves outside the brain and spinal cord, and the central nervous system (D) includes the brain and spinal cord. Understanding the functions and divisions of the nervous system is crucial for grasping how different bodily processes are controlled and regulated.
