1. Which protein complex in the sarcomere is responsible for the thick filament?

Correct answer: B

Rationale: Myosin is the protein complex responsible for the thick filament in the sarcomere. It interacts with actin, another protein in the sarcomere, to generate the sliding movement that results in muscle contraction. Actin is a thin filament protein that interacts with myosin to create the sliding filament mechanism. Tropomyosin and troponin are regulatory proteins that regulate muscle contraction by controlling the interaction between actin and myosin, rather than directly being responsible for the thick filament.

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

Correct answer: B

Rationale: Vacuoles in animal cells primarily function in waste storage and disposal, helping to maintain cellular homeostasis by storing waste products and aiding in their removal from the cell. Unlike plant cells, animal cells do not typically use vacuoles for storage purposes such as water, nutrients, or pigments. Instead, animal cells rely on other organelles like lysosomes for waste management and maintaining cellular balance. Choices A, C, and D are incorrect because protein synthesis occurs in ribosomes, photosynthesis takes place in chloroplasts (absent in animal cells), and cellular respiration mainly occurs in mitochondria, respectively. Vacuoles in animal cells serve a different purpose compared to plant cells.

3. When students use inference, what are they able to do?

Correct answer: A

Rationale: When students use inference, they are able to make logical assumptions based on contextual clues found in the text. This involves reading between the lines and drawing conclusions that are not explicitly stated. Choice B is incorrect because it refers to the skill of navigating through different types of text independently, which is not specifically related to inference. Choices C and D are also incorrect as they refer to summarizing and paraphrasing a text's main idea, which are different skills from making inferences.

4. Which enzyme breaks down carbohydrates like starches and sugars in the mouth?

Correct answer: C

Rationale: The correct answer is Amylase. Amylase is the enzyme responsible for breaking down carbohydrates like starches and sugars in the mouth. Pepsin is a digestive enzyme that breaks down proteins in the stomach, lipase breaks down fats, and trypsin is another enzyme that breaks down proteins in the small intestine. Therefore, choices A, B, and D are incorrect for this question.

5. In which chapter should Clothilde look for more information?

Correct answer: B

Rationale: Clothilde should look for more information in Chapter 9, 'Herbs for Immunity,' as her sister's daughter has a chronic cough. Immune-boosting herbs may help strengthen the child's immune system and potentially alleviate the cough. Chapter 9 focuses on herbs that support immune health, making it the most relevant chapter for addressing a chronic cough related to immunity. Chapters 7, 10, and 12 do not specifically focus on immunity or respiratory conditions, making them less likely to provide the information Clothilde needs.
