1. Which organ is responsible for detoxifying harmful substances in the body?

• A. Kidneys
• B. Liver
• C. Heart
• D. Pancreas

Correct answer: B

Rationale: The correct answer is the Liver. The liver is the organ responsible for detoxifying harmful substances in the body. It accomplishes this by metabolizing drugs and filtering blood. The liver plays a crucial role in maintaining overall health by processing and eliminating toxins. Choices A, C, and D are incorrect. The kidneys primarily filter blood to remove waste and excess substances, the heart is responsible for pumping blood throughout the body, and the pancreas aids in digestion and regulating blood sugar levels, but none of these organs are primarily responsible for detoxification.

2. Which of the following sentences correctly uses a transition word?

• A. Gilda is a hardworking student; therefore, she earned a good grade on her essay.
• B. Gilda is a hardworking student; therefore she earned a good grade on her essay.
• C. Gilda is a hardworking student: therefore, she earned a good grade on her essay.
• D. Gilda is a hardworking student and therefore she earned a good grade on her essay.

Correct answer: A

Rationale: Choice A is the correct answer. 'Therefore' is correctly used as a transition word with proper punctuation in this sentence. In a compound sentence like this, a semicolon is used before the transition word to connect two independent clauses. Choice B is incorrect because it lacks the necessary punctuation to separate the independent clauses. Choice C is incorrect as a colon is not typically used before a transition word in this context. Choice D is incorrect because 'and' does not function as a transition word in this sentence.

3. What is kwashiorkor, a protein deficiency disease, characterized by?

• A. Muscle wasting
• B. Night blindness
• C. Scurvy
• D. Rickets

Correct answer: A

Rationale: Kwashiorkor is a severe acute malnutrition condition resulting from insufficient dietary protein intake. It is characterized by symptoms such as edema, skin lesions, an enlarged liver with fatty infiltrates, and notably, muscle wasting. Muscle wasting occurs as the body breaks down muscle tissue to obtain essential amino acids for vital functions. Night blindness (option B) is associated with vitamin A deficiency, scurvy (option C) results from a lack of vitamin C, and rickets (option D) is caused by a deficiency in vitamin D, calcium, or phosphate.

4. Dendrites are finger-like extensions found on

• A. Muscle cells
• B. Connective tissue cells
• C. Neurons
• D. Epithelial cells

Correct answer: C

Rationale: Dendrites are the branched extensions of neurons that receive signals from other neurons and transmit those signals to the cell body. They play a crucial role in the communication process within the nervous system, allowing neurons to communicate with each other and integrate incoming signals to generate responses. The other choices are incorrect because dendrites specifically belong to neurons, not muscle cells, connective tissue cells, or epithelial cells.

5. What is the underlined portion of the sentence an example of? New students should report to the student center.

• A. Dependent clause
• B. Adverbial phrase
• C. Adjective clause
• D. Noun phrase

Correct answer: D

Rationale: The correct answer is D, 'Noun phrase.' In the sentence 'New students should report to the student center,' the underlined portion 'new students' is a noun phrase functioning as the subject of the sentence. A dependent clause is a group of words with a subject and verb that does not express a complete thought, which is not the case here. An adverbial phrase modifies a verb, adjective, or adverb and typically answers questions like 'how,' 'when,' 'where,' or 'why,' which is not applicable in this context. An adjective clause is a group of words that describe a noun, but 'new students' in the sentence is not serving as a descriptive element of another noun; instead, it is the main subject.
