1. What are the two main divisions of the skeletal system?

• A. Upper and lower body bones
• B. Axial and appendicular skeleton
• C. Long and short bones
• D. Compact and spongy bone

Correct answer: B

Rationale: The skeletal system is divided into two main divisions: the axial skeleton and the appendicular skeleton. The axial skeleton comprises the skull, vertebral column, and rib cage, providing structural support and protection for vital organs. On the other hand, the appendicular skeleton includes the bones of the upper and lower limbs, shoulder girdle, and pelvic girdle, facilitating movement and flexibility. The divisions are based on the location and function of the bones within the skeletal system, making choices A, C, and D incorrect as they do not represent the primary divisions of the skeletal system.

2. Passive transport does not require energy input from the cell. Which of the following is an example of passive transport?

• A. Active transport of ions across a membrane
• B. Diffusion of small molecules across a concentration gradient
• C. Movement of large molecules using vesicles
• D. Endocytosis of particles into the cell

Correct answer: B

Rationale: Passive transport refers to the movement of molecules across a cell membrane without the input of energy. Diffusion of small molecules across a concentration gradient is a classic example of passive transport, as it occurs spontaneously from an area of high concentration to an area of low concentration. Active transport (option A) requires energy input in the form of ATP to move substances against their concentration gradient. Movement of large molecules using vesicles (option C) involves processes like endocytosis and exocytosis that require energy in the form of ATP. Endocytosis of particles into the cell (option D) is an active process that requires energy expenditure by the cell to engulf and internalize extracellular substances.

3. Which conjunction best joins the following sentence: 'She loves animals, ____ she volunteers at the shelter.'

• A. because
• B. therefore
• C. so
• D. and

Correct answer: D

Rationale: The correct answer is 'and.' 'And' is the most appropriate conjunction here as it simply adds information about her love for animals without implying cause or effect. It connects two independent clauses in a neutral way, indicating that she loves animals and also volunteers at the shelter. The other choices, 'because,' 'therefore,' and 'so,' suggest a cause-and-effect relationship between loving animals and volunteering at the shelter, which is not the intended meaning in this context.

4. Which of the following verb forms correctly completes the sentence? His charismatic personality, organizational abilities, sheer determination, and rhetorical skills enable him to quickly rise through the chapter's ranks.

• A. NO CHANGE
• B. are enabling him to quickly rise
• C. enabled him to quickly rise
• D. will enable him to quickly rise

Correct answer: C

Rationale: Option C, 'enabled him to quickly rise,' is the correct choice. The sentence is referring to a past action, so the verb should be in the past tense. 'Enabled' is the correct past tense form of 'enable' in this context. Choice A ('NO CHANGE') is incorrect because it does not match the past tense required by the sentence. Option B ('are enabling him to quickly rise') is incorrect as it uses the present continuous tense, which is not suitable for the past action described. Choice D ('will enable him to quickly rise') is incorrect as it implies a future action, which is not consistent with the context of the sentence.

5. What is the correct plural form of the noun 'class'?

• A. Class
• B. Class'
• C. Class's
• D. Classes

Correct answer: D

Rationale: The correct plural form of the noun 'class' is 'classes.' When forming the plural of 'class,' you add 'es' to the singular form. Choices A, B, and C do not correctly represent the plural form of 'class' and are therefore incorrect. Choice A is the singular form, choice B is incorrect as it includes an apostrophe, and choice C shows possession which is not required for pluralization.
