1. Microfilaments and microtubules are both components of the cytoskeleton, but they have different functions. Which of these describes microfilaments?

• A. Provide structural support and shape
• B. Facilitate cell movement and contraction
• C. Form the mitotic spindle during cell division
• D. Transport materials within the cell

Correct answer: A

Rationale: Microfilaments are thin, solid rods made of the protein actin and are primarily responsible for providing structural support to the cell and determining its shape. While they also play a role in cell movement, their main function is related to maintaining the structural integrity of the cell. Choice B, 'Facilitate cell movement and contraction,' describes microtubules, which are responsible for facilitating cell movement, providing structural support, and aiding in cell division. Choice C, 'Form the mitotic spindle during cell division,' specifically refers to the function of microtubules in forming the mitotic spindle. Choice D, 'Transport materials within the cell,' is characteristic of microtubules that are involved in intracellular transport of organelles and materials within the cell.

2. What are the fundamental units of structure and function in all living organisms, including humans, termed?

• A. Muscles
• B. Organs
• C. Tissues
• D. Cells

Correct answer: D

Rationale: Cells are the fundamental units of structure and function in all living organisms. They are the basic building blocks of life and carry out essential functions necessary for an organism to survive and function properly. Muscles, organs, and tissues are composed of cells, but cells are the smallest unit that can carry out all the functions of life. Muscles are made up of muscle tissue, which in turn is composed of muscle cells. Organs are structures made up of different types of tissues working together, and tissues are groups of cells with a similar structure and function. Therefore, while muscles, organs, and tissues are important components of living organisms, cells are the fundamental units that perform all the vital functions of life.

3. Which of the following are properties of a liquid?

• A. High atomic attraction
• B. Fixed volume
• C. Low pressure
• D. Takes shape of container

Correct answer: D

Rationale: The correct answer is D: 'Takes shape of container.' Liquids exhibit the property of taking the shape of their container while maintaining a fixed volume. This is due to the ability of liquid particles to flow and move freely within the container. Choices A, B, and C are incorrect. Choice A, 'High atomic attraction,' is not a general property of liquids as the level of attraction between liquid particles can vary. Choice B, 'Fixed volume,' is partially correct as liquids do have a fixed volume, but they do not have a fixed shape. Choice C, 'Low pressure,' is not a defining property of liquids.

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

• A. around
• B. chased
• C. squirrel
• D. the

Correct answer: B

Rationale: A verb is a word that expresses an action or state of being. In this sentence, 'chased' is the verb as it describes the action the dog is performing - chasing the fluffy squirrel. 'Around' is a preposition indicating location, 'squirrel' is a noun referring to the animal being chased, and 'the' is an article used to specify the squirrel. Therefore, the correct answer is 'chased.'

5. Which of the following best explains the meaning of fastidious as it is used in the sentence? "Henry was fastidious about keeping his workspace organized, ensuring that every item was always in its proper place."

• A. fussy
• B. lazy
• C. old-fashioned
• D. hilarious

Correct answer: A

Rationale: In this context, the word 'fastidious' describes someone who pays great attention to detail, is very meticulous, and particular about things being perfect. Henry's behavior of keeping his workspace organized and ensuring everything is in its proper place indicates his meticulous nature. 'Fussy' aligns best with this meaning as it conveys being hard to please and excessively attentive to detail, which accurately describes Henry's behavior. Choices B, C, and D are incorrect as they do not capture the essence of being meticulous and attentive to detail, which is the central meaning conveyed by 'fastidious' in this context.
