1. Imagine that two parents both carry the recessive gene for cystic fibrosis. Any homozygous recessive offspring will manifest the disease. What percentage of the offspring is predicted to be carriers but not manifest the disease?

• A. 0%
• B. 25%
• C. 50%
• D. 100%

Correct answer: B

Rationale: When both parents carry the recessive gene for cystic fibrosis (homozygous recessive), there is a 25% chance for each offspring to inherit two recessive alleles and, therefore, manifest the disease. There is also a 50% chance for each offspring to inherit one recessive allele and one dominant allele, making them carriers of the disease but not manifest it. Therefore, 25% of the offspring are predicted to be carriers but not manifest the disease. Choice A (0%) is incorrect because there is a portion of offspring that will be carriers. Choice C (50%) is incorrect as this percentage corresponds to carriers who will not manifest the disease. Choice D (100%) is incorrect as not all offspring will be carriers and not manifest the disease.

2. The US __________ most of its silicone chips from Japan and China to stay competitive in the tech market.

• A. Deports
• B. Exports
• C. Reports
• D. Imports

Correct answer: D

Rationale: The US imports most of its silicone chips from Japan and China, indicating that the silicone chips are being brought into the US from these countries. 'Imports' refers to the act of bringing goods or services into one country from another, which accurately describes the scenario described in the question. The other choices are incorrect: 'Deports' means expelling individuals from a country, 'Exports' mean sending goods to another country, and 'Reports' mean providing information or data.

3. Which element has the highest atomic number?

• A. Uranium
• B. Hydrogen
• C. Radon
• D. Bismuth

Correct answer: A

Rationale: The correct answer is Uranium. The atomic number represents the number of protons in an atom's nucleus. Among the options provided, Uranium has the highest atomic number, which is 92. Hydrogen has an atomic number of 1, Radon has an atomic number of 86, and Bismuth has an atomic number of 83. Therefore, Uranium is the element with the highest atomic number in the given choices.

4. Select the word or phrase that makes this sentence grammatically correct: 'Children ____ obey their parents tend to do better in school.'

• A. who
• B. which
• C. should
• D. to

Correct answer: A

Rationale: In this sentence, 'who' is the correct pronoun to refer to 'Children,' indicating that children are the ones who obey their parents. Using 'who' makes the sentence grammatically correct by connecting the subject 'children' with the verb 'obey.' The pronoun 'which' is used for things, not people, so it is incorrect. 'Should' and 'to' do not fit in the context of the sentence and do not provide the necessary connection between 'children' and 'obey.' Therefore, the correct choice is 'who.'

5. What is a Nutrient?

• A. A chemical compound
• B. A substance that provides nourishment
• C. A non-essential mineral
• D. An essential vitamin

Correct answer: B

Rationale: A nutrient is a substance that provides nourishment to the body, such as carbohydrates, proteins, fats, vitamins, and minerals. Choice A has been improved to 'A chemical compound' to be more specific. Choice A is incorrect as it is too general and does not specifically describe the role of a nutrient. Choice C is incorrect as it focuses on minerals without specifying that all minerals are nutrients. Choice D is also incorrect as it solely emphasizes vitamins, which are just one type of nutrient.
