Chemistry

1. How do isotopes affect the atomic mass of an element?

Correct answer: B

Rationale: The atomic mass of an element is the average mass of all the isotopes of that element. Since isotopes have different numbers of neutrons, they also have slightly different masses. This variation in mass is what causes the atomic mass of an element to be a decimal number, rather than a whole number.

2. The human body's largest organ, responsible for detoxification and a multitude of other functions, is the:

Correct answer: B

Rationale: The correct answer is B: Liver. The liver is the largest internal organ in the human body and is responsible for detoxification, processing nutrients, producing bile, and regulating blood sugar levels, among other functions. While the heart is vital for pumping blood, the lungs are crucial for respiration, and the skin is the body's largest external organ, the liver plays a central role in detoxification and various metabolic processes, making it the correct answer to this question.

3. Which property of a substance remains constant regardless of changes in its shape or size?

Correct answer: a

Rationale: Mass is the measure of the amount of matter in an object and remains constant regardless of changes in its shape or size.

4. Which structure in the respiratory system serves as the "windpipe" that conducts air from the larynx to the bronchi?

Correct answer: A

Rationale: The correct answer is A: Trachea. The trachea, also known as the windpipe, is a tube-like structure in the respiratory system that connects the larynx to the bronchi. It serves as the main airway for the passage of air into and out of the lungs. The larynx is commonly known as the voice box and is responsible for producing sound. The bronchi are the two branches that stem from the trachea and lead to the lungs, where they further divide into smaller airways. The alveoli are tiny air sacs in the lungs where gas exchange occurs. Therefore, the trachea is the correct answer as it directly conducts air from the larynx to the bronchi.

5. Identify the verb in the following sentence: The dog chased the fluffy squirrel around the oak tree.

Correct answer: B

Rationale: Verbs express actions or states of being. In this sentence, "chased" describes what the dog did.

6. What is the process by which lighter nuclei fuse to form heavier nuclei, releasing a large amount of energy?

Correct answer: B

Rationale: Fusion is the process by which lighter nuclei combine to form heavier nuclei, releasing a large amount of energy in the process. This process is the source of energy in stars, including our Sun, and is different from fission, which involves the splitting of heavier nuclei into lighter nuclei. Radioactivity refers to the emission of particles or radiation from the nucleus of an unstable atom, while a chain reaction is a self-sustaining reaction where the products of one reaction cause further reactions.
