1. Select the context clue from the following sentence that helps you define the word 'emulate': Felicia always tried to emulate her big sister, so she would often imitate the way she spoke, moved, and dressed.

• A. tried
• B. often
• C. imitate
• D. way

Correct answer: C

Rationale: The correct answer is 'C: imitate.' In the sentence, it is explicitly stated that Felicia would often imitate her big sister, which directly relates to the meaning of 'emulate' as to copy or imitate someone else. 'Tried' (choice A) does not provide a direct connection to the definition of 'emulate.' 'Often' (choice B) and 'way' (choice D) are not directly associated with the act of imitating or copying, making them less relevant context clues for defining 'emulate.'

2. What is the structure that attaches to each chromosome during mitosis?

• A. Centromere
• B. Telomere
• C. Spindle apparatus
• D. Nucleolus

Correct answer: A

Rationale: The correct answer is the centromere. It is the structure that attaches to each chromosome during mitosis. The centromere serves as the attachment point for spindle fibers during cell division, ensuring proper distribution of chromosomes to daughter cells. Telomeres are found at the ends of chromosomes, providing protection and stability. The spindle apparatus is responsible for separating chromosomes during cell division. The nucleolus, located within the nucleus, is involved in ribosomal RNA synthesis and not in chromosome attachment during mitosis.

3. How many amino acids can make up a protein?

• A. 10-20
• B. 50-100
• C. 100-500
• D. 1000+

Correct answer: A

Rationale: Proteins are made up of long chains of amino acids, and there are 20 standard amino acids commonly found in proteins. The sequence and arrangement of these amino acids determine the structure and function of a protein. While proteins can vary in size and complexity, the number of amino acids typically ranges from around 10 to 20 in smaller proteins to hundreds or even thousands in larger proteins. Therefore, the range of 10-20 amino acids is the most accurate representation of the number of amino acids that can make up a protein. Choices B, C, and D are incorrect as they provide ranges that are beyond the typical number of amino acids found in proteins and may lead to confusion. The correct answer is A (10-20).

4. What is 1500 milliliters in liters?

• A. 1.5 liters
• B. 0.15 liters
• C. 15 liters
• D. 0.015 liters

Correct answer: A

Rationale: To convert milliliters to liters, you need to divide by 1000 since there are 1000 milliliters in 1 liter. Therefore, 1500 milliliters divided by 1000 equals 1.5 liters, making option A the correct answer. Option B, 0.15 liters, is incorrect as it would be the conversion of 150 milliliters. Option C, 15 liters, is incorrect because it would be the conversion of 15,000 milliliters. Option D, 0.015 liters, is incorrect as it would be the conversion of 15 milliliters.

5. Based on the words transfer, transact, translation, transport, what is the meaning of the prefix trans?

• A. Separation
• B. All, everywhere
• C. Forward
• D. Across, beyond, over

Correct answer: D

Rationale: The prefix 'trans-' in words such as transfer, transact, translation, and transport signifies movement or change from one place, state, or form to another. It indicates going across, beyond, or over something, connecting the original state to a different one. Choice A, 'Separation,' is incorrect as the prefix 'trans-' does not imply separation but rather movement or change between states. Choice B, 'All, everywhere,' is incorrect as the prefix does not convey a sense of being all-encompassing but rather focuses on the action of crossing or changing. Choice C, 'Forward,' is incorrect as the prefix 'trans-' is more about moving across or beyond rather than strictly forward.
