1. Dendrites are finger-like extensions found on

Correct answer: C

Rationale: Dendrites are the branched extensions of neurons that receive signals from other neurons and transmit those signals to the cell body. They play a crucial role in the communication process within the nervous system, allowing neurons to communicate with each other and integrate incoming signals to generate responses. The other choices are incorrect because dendrites specifically belong to neurons, not muscle cells, connective tissue cells, or epithelial cells.

2. What is the function of the pituitary gland?

Correct answer: A

Rationale: The correct answer is A: Produces hormones that regulate growth and metabolism. The pituitary gland is often referred to as the 'master gland' because it produces and releases hormones that regulate various bodily functions, including growth, metabolism, reproduction, and stress response. It does not filter blood or remove waste products (option B), store and release bile (option C), or produce red blood cells (option D). The pituitary gland's primary role is in hormone production and regulation, influencing many essential functions in the body.

3. What determines the final velocity of a block sliding down a frictionless inclined plane?

Correct answer: B

Rationale: The final velocity of a block sliding down a frictionless inclined plane is determined by the angle of the incline. The angle directly impacts the acceleration of the block, affecting the final velocity it attains at the bottom. The length of the incline and the mass of the block do not play a direct role in determining the final velocity. Therefore, the correct answer is the angle of the incline (Choice B). Choices A and C are incorrect because the length of the incline and the mass of the block do not have a direct influence on the final velocity of the block in this scenario.

4. How does the mass of an object affect its inertia?

Correct answer: B

Rationale: Inertia is the resistance of an object to changes in its state of motion. The greater the mass of an object, the greater its inertia because it requires more force to change its state of motion. This concept aligns with Newton's first law of motion, which states that an object at rest will remain at rest, and an object in motion will continue in motion with the same speed and direction unless acted upon by an external force. Therefore, higher mass increases inertia, making it more difficult to alter the object's state of motion. Choice A is incorrect as mass does impact inertia. Choice C is incorrect as higher mass actually increases inertia, not decreases it. Choice D is incorrect as while mass does affect gravitational force, it also directly impacts inertia.

5. Which hormone plays a key role in stimulating the release of milk from breast tissue after childbirth?

Correct answer: C

Rationale: Prolactin is the hormone responsible for stimulating the release of milk from breast tissue after childbirth. It is produced by the pituitary gland and plays a crucial role in lactation. Follicle-stimulating hormone (FSH) and luteinizing hormone (LH) are involved in the menstrual cycle and reproductive processes, not milk production. Estrogen is a female sex hormone with various functions but is not directly involved in milk production.
