1. Vacuoles are large sacs for storage in plant cells. What is their main function in animal cells?

Correct answer: B

Rationale: Vacuoles in plant cells are primarily used for storage of water, nutrients, and waste products. In animal cells, vacuoles are smaller and serve various functions, including waste storage and disposal. Option B, 'Waste storage and disposal,' is the correct answer because vacuoles in animal cells help maintain cellular homeostasis by storing and breaking down waste materials. This process aids in detoxification and maintaining proper cellular function in animal cells, similar to the role of vacuoles in plant cells.

2. Which of the following is an example of a nonpolar solvent?

Correct answer: B

Rationale: Rationale: - Water (option A) is a polar solvent due to its uneven distribution of charge, with the oxygen atom being partially negative and the hydrogen atoms being partially positive. - Ethanol (option B) is a nonpolar solvent because it has a symmetrical molecular structure that does not result in significant charge separation. - Acetone (option C) is a polar solvent as it contains a carbonyl group that results in a partial negative charge on the oxygen atom. - Hydrochloric acid (option D) is a polar solvent due to the presence of the highly electronegative chlorine atom, which results in a partial negative charge.

3. The artist paints breathtaking landscapes. What is the third-person singular, present tense form of the verb "paint"?

Correct answer: B

Rationale: Verbs change depending on the subject (person) and time (tense).

4. Which of the following is NOT a common site for lymph nodes?

Correct answer: D

Rationale: The correct answer is D: 'Liver.' Lymph nodes are small, bean-shaped structures that are part of the lymphatic system. They are commonly found in areas such as the groin, armpit, and neck, where they help filter and trap harmful substances. The liver, while an important organ in the body, does not typically contain lymph nodes. Therefore, it is not a common site for lymph nodes. Understanding the locations of lymph nodes in the body is important for identifying potential sources of infection or cancer when assessing patients.

5. Which of the following is the main organ responsible for storing energy?

Correct answer: D

Rationale: Rationale: - Adipose tissue, commonly known as body fat, is the main organ responsible for storing energy in the form of triglycerides. - The liver plays a role in energy metabolism by regulating glucose levels and storing glycogen, but its primary function is not energy storage. - The heart is a muscular organ responsible for pumping blood throughout the body and does not play a significant role in energy storage. - The kidneys are vital organs responsible for filtering blood and regulating fluid balance, but they are not primarily involved in energy storage.

6. In the sentence "The house was dilapidated," what effect does the word "dilapidated" have on the reader's understanding?

Correct answer: C

Rationale: The word "dilapidated" specifically describes the house's deteriorating state.
