1. Which organelle is responsible for storing genetic material?

• A. Mitochondria
• B. Nucleus
• C. Ribosome
• D. Endoplasmic reticulum

Correct answer: B

Rationale: The correct answer is the Nucleus. The nucleus is responsible for storing genetic material (DNA) and controlling cell functions. Mitochondria are known for energy production, not genetic storage. Ribosomes are involved in protein synthesis, not genetic material storage. The endoplasmic reticulum is involved in protein and lipid synthesis, not genetic material storage. Therefore, the nucleus is the organelle primarily responsible for housing the genetic material within a cell.

2. Select the context clue from the following sentence that helps you define the multiple meaning word formula: 'The mother gave her baby his formula after he woke up from his nap in the car.'

• A. mother
• B. baby
• C. nap
• D. car

Correct answer: B

Rationale: The correct answer is 'B: baby.' In the sentence, 'baby' is the context clue that helps define the multiple meaning word 'formula.' Here, 'formula' refers to baby food, as babies typically consume formula. The word 'baby' directly relates to the context of feeding a baby with formula. Choice A, 'mother,' is not directly related to the meaning of 'formula' in this context. Choices C and D, 'nap' and 'car,' are also not directly connected to the meaning of 'formula' as they do not provide any relevant information about the word's meaning in this sentence.

3. Which of the following sets of words correctly fill in the blanks in the sentence below: We cannot allow the budget cuts to _______ the plans to improve education; the futures of _______ children are at stake.

• A. effect; your
• B. affect; you're
• C. affect; your
• D. effect; you're

Correct answer: C

Rationale: In this sentence, 'affect' is the correct verb meaning 'to influence,' and 'your' is the correct possessive pronoun. Therefore, the sentence should read, 'We cannot allow the budget cuts to affect the plans to improve education; the futures of your children are at stake.' Choice A is incorrect because 'effect' is a noun, not a verb, and 'your' is the correct possessive pronoun. Choice B is incorrect because 'you're' is a contraction for 'you are,' which does not make sense in this context. Choice D is incorrect because 'effect' should be 'affect' as the verb is needed to show influence.

4. If the mass of an object remains constant and its velocity doubles, how does its momentum change?

• A. Momentum doubles
• B. Momentum halves
• C. Momentum quadruples
• D. Momentum remains the same

Correct answer: C

Rationale: Momentum is calculated as the product of an object's mass and its velocity. When the mass remains constant and the velocity doubles, the momentum will increase by a factor of 2 (doubling) due to the increase in velocity. Therefore, the momentum will quadruple (2 x 2 = 4) when the velocity doubles. This relationship between momentum and velocity showcases the direct proportionality of momentum to velocity, given a constant mass. Choices A, B, and D are incorrect. Momentum does not simply double or halve when the velocity doubles; it quadruples as it is directly proportional to the velocity. Hence, the correct answer is C, where momentum quadruples in this scenario.

5. Which of the following is a function of the liver?

• A. Producing digestive enzymes
• B. Storing bile
• C. Filtering waste products from the blood
• D. Transporting nutrients to cells

Correct answer: B

Rationale: The correct function of the liver is to store bile. Bile is produced in the liver and stored in the gallbladder until it is needed to aid in the digestion of fats. While the liver does produce bile, its primary role is to store and release it. Choices A, C, and D are incorrect. Producing digestive enzymes is mainly the function of the pancreas, filtering waste products from the blood is primarily done by the kidneys, and transporting nutrients to cells is typically associated with the circulatory system rather than the liver.
