1. What is the term for the involuntary muscle contractions that move food through the digestive tract?

• A. Segmentation
• B. Peristalsis
• C. Chyme
• D. Emulsification

Correct answer: B

Rationale: Peristalsis is the correct term for the involuntary muscle contractions that move food through the digestive tract. These contractions help push food along the digestive system, facilitating digestion and absorption of nutrients. Segmentation, on the other hand, refers to the mixing and breaking down of food in the intestines, not the movement of food. Chyme is the semi-fluid mass of partially digested food in the stomach and small intestine, not the muscle contractions. Emulsification is the process of breaking down fat globules into smaller droplets to aid in digestion, not the movement of food through the digestive tract. Therefore, peristalsis is the most appropriate term for this function.

2. 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.

3. What is 0.04 grams converted to milligrams?

• A. 40 mg
• B. 4 mg
• C. 400 mg
• D. 0.4 mg

Correct answer: A

Rationale: To convert grams to milligrams, you need to multiply by 1000, not 10000. Therefore, to convert 0.04 grams to milligrams, you multiply 0.04 by 1000, which equals 40 mg. Choice A (40 mg) is the correct answer. Choice B (4 mg) is incorrect as it represents converting 0.004 grams to milligrams. Choice C (400 mg) is incorrect as it is 10 times the correct conversion. Choice D (0.4 mg) is incorrect as it is 10 times smaller than the correct conversion.

4. Which of the following sentences would be classified as informal language?

• A. I'm counting on you to finish this before the deadline.
• B. The deadline presented by the CEO is non-negotiable.
• C. Every member of the department must meet the deadline.
• D. The time period prior to the deadline is extremely significant.

Correct answer: A

Rationale: The correct answer is A: "I'm counting on you to finish this before the deadline." This sentence is classified as informal language due to the use of contractions (I'm) and the casual tone of the phrase. The other choices (B, C, D) are more formal in nature. Choice B uses formal language with terms like 'non-negotiable.' Choice C is a general statement about meeting a deadline without any informal language, and choice D discusses the significance of the time period before a deadline in a formal manner.

5. Muscle tissues often require quick bursts of energy. As a result, which of the following organelles would be most likely to be found in higher than normal amounts in muscle cells?

• A. ribosomes
• B. chloroplasts
• C. vacuoles
• D. mitochondria

Correct answer: D

Rationale: Muscle tissues require quick bursts of energy for activities such as contraction and relaxation. Mitochondria are known as the powerhouse of the cell, producing energy in the form of ATP through cellular respiration. Therefore, muscle cells would require higher amounts of mitochondria to meet their energy demands. Ribosomes are involved in protein synthesis and are not directly related to energy production. Chloroplasts are found in plant cells and are responsible for photosynthesis, not in animal muscle cells. Vacuoles are primarily involved in storage, maintaining turgor pressure, and digestion, but they are not the main organelles involved in energy production.
