1. The removal of wastes produced by metabolic reactions is

• A. metabolism.
• B. absorption.
• C. assimilation.
• D. excretion.

Correct answer: D.

Rationale: The correct answer is 'excretion.' Excretion is the process of eliminating waste products produced by metabolic reactions from the body. Metabolism (Choice A) refers to the chemical processes that occur within a living organism to maintain life. Absorption (Choice B) is the process of taking in nutrients and fluids into the body. Assimilation (Choice C) is the process of absorbing and incorporating nutrients into the body after digestion. Therefore, excretion is the most appropriate term for the removal of metabolic wastes.

2. Macromolecules are built of?

• A. Monomers
• B. Incorrect
• C. Not Applicable
• D. None of the above

Correct answer: A

Rationale: The correct answer is A: Monomers. Macromolecules are built from smaller subunits called monomers. Monomers join together through chemical reactions to form larger molecules known as macromolecules. Option B is incorrect as it does not provide the accurate information regarding the composition of macromolecules. Option C is not applicable as it does not offer a relevant choice. Option D is incorrect because there is a specific answer related to the composition of macromolecules.

3. Do we know all there is to know about the structure and function of the human body?

• A. Yes
• B. No
• C. Not Sure
• D. None of the above

Correct answer: B

Rationale: No, the statement that we know all there is to know about the structure and function of the human body is false. The human body is complex, and there is still much to discover and understand about its intricate functions. Science and medicine continue to make new discoveries and advancements in understanding the human body. Choice A is incorrect because it claims that we know everything, which is not true. Choice C is not the best answer as it implies uncertainty rather than acknowledging the ongoing research and discoveries in this field. Choice D is not the correct option as there is a definitive answer to the question.

4. Paired organs, such as the kidneys or lungs, are said to be

• A. bisexual.
• B. bilingual.
• C. bilateral.
• D. bivalent.

Correct answer: C

Rationale: The correct answer is C: 'bilateral.' Paired organs like the kidneys or lungs are described as bilateral because they occur in pairs on both sides of the body. Option A 'bisexual' refers to having both male and female reproductive organs, which is not the correct term for paired organs. Option B 'bilingual' refers to being able to speak two languages, which is not related to the description of paired organs. Option D 'bivalent' means having two valences, which is also unrelated to the context of paired organs.

5. An investigator who conducts an experiment to determine how temperature changes affect the rate at which the heart beats is most likely a(n)

• A. anatomist.
• B. physiologist.
• C. chemist.
• D. biochemist.

Correct answer: B

Rationale: The correct answer is 'physiologist.' A physiologist studies how the body functions under normal and abnormal conditions, including how temperature changes can affect physiological processes like heart rate. An anatomist focuses on the structure of organisms rather than their functions, making choice A incorrect. Choices C and D are also incorrect as they are more related to the study of chemicals and biochemistry, which are not directly relevant to investigating the effects of temperature on heart rate.
