physics

1. Which property of a substance refers to its ability to be stretched into thin wires?

Correct answer: c

Rationale: Ductility refers to a substance's ability to be stretched into thin wires without breaking.

2. What is the function of a cell wall?

Correct answer: A

Rationale: Rationale: The cell wall is a rigid layer that surrounds the cell membrane in plant cells, fungi, and some bacteria. Its main function is to provide structural support and protection for the cell, helping maintain the cell's shape and preventing it from bursting or collapsing. The cell wall also allows for the passage of water, ions, and other molecules in and out of the cell. Options B, C, and D are incorrect because those functions are typically carried out by other cellular structures such as the cell membrane, ribosomes, and nucleus, respectively.

3. What is the largest part of the brain and is responsible for higher functions like thinking, memory, and learning?

Correct answer: C

Rationale: The correct answer is C: Cerebrum. The cerebrum is the largest part of the brain and is responsible for higher functions like thinking, memory, and learning. It is divided into two hemispheres (left and right) and is associated with intelligence, creativity, reasoning, and problem-solving abilities. The brainstem (option A) is responsible for basic life functions like breathing and heart rate. The cerebellum (option B) is involved in coordination and balance. The thalamus (option D) acts as a relay station for sensory information. Therefore, the cerebrum is the most appropriate choice for the part of the brain responsible for higher cognitive functions.

4. The involuntary "fight-or-flight" response is controlled by the:

Correct answer: A

Rationale: The correct answer is A: Sympathetic nervous system. The "fight-or-flight" response is an automatic physiological reaction triggered by the sympathetic nervous system in response to a perceived threat or stressor. This system prepares the body for action by increasing heart rate, dilating pupils, and redirecting blood flow to muscles. The parasympathetic nervous system, on the other hand, controls the body's "rest-and-digest" response, promoting relaxation and digestion. The enteric nervous system primarily regulates the gastrointestinal system, while the sensory nervous system is responsible for transmitting sensory information to the brain. Therefore, the sympathetic nervous system is specifically responsible for initiating the fight-or-flight response.

5. A scientific theory is:

Correct answer: B

Rationale: Theories in science are constantly evolving and open to revision as new data emerges, unlike personal beliefs or fixed dogmas.

6. Which element is a component of baking soda and is important for maintaining pH balance in the body?

Correct answer: D

Rationale: Sodium bicarbonate acts as a base and helps regulate pH in various biological systems
