1. Which of the following describes the situation where one allele takes a different form from another in a gene?

• A. phenotype
• B. heterozygous
• C. homolog
• D. homozygous

Correct answer: B

Rationale: Heterozygous is the term used to describe the genotype of an individual with two different alleles for a specific gene. In this case, one allele takes a different form from another, resulting in genetic diversity and variation in trait expression. The other choices are incorrect: 'phenotype' refers to the observable traits of an organism, 'homolog' typically refers to chromosomes that are similar in structure, and 'homozygous' describes the genotype where both alleles for a gene are the same.

2. Select the word that makes the following sentence grammatically correct. Having ___________ one pill at bedtime, the patient was able to sleep for eight hours.

• A. took
• B. take
• C. taking
• D. taken

Correct answer: C

Rationale: The correct word to use in this sentence is 'taking' to show the continuous aspect of the action. The sentence should read: 'Having taking one pill at bedtime, the patient was able to sleep for eight hours.' 'Taking' is the present participle form of the verb 'take,' which is appropriate in this context to indicate the ongoing action of taking a pill at bedtime. Choice A, 'took,' is incorrect as it is the simple past tense, not suitable for this sentence's structure. Choice B, 'take,' is the base form of the verb, which does not fit the sentence's requirement for a participle. Choice D, 'taken,' is the past participle form, which is also unsuitable for showing the ongoing action required in this context.

3. What does 'expand' mean?

• A. To decrease in size
• B. To increase in size or amount
• C. To spread out
• D. To eliminate

Correct answer: B

Rationale: The correct answer is B. 'Expand' means to increase in size or amount. Choice A, 'To decrease in size,' is the opposite of what 'expand' means. Choice C, 'To spread out,' is related to expanding but does not precisely define the term. Choice D, 'To eliminate,' is not synonymous with the term 'expand.'

4. What is another word for deluge?

• A. Earthquake
• B. Dimness
• C. Downpour
• D. Chasm

Correct answer: C

Rationale: A "deluge" is a sudden and heavy rainfall or flood, so the word that is most closely related in meaning to "deluge" is "downpour," which also refers to a heavy and sustained rainfall. The other choices, "earthquake," "dimness," and "chasm," do not relate to a flooding or heavy rainfall situation.

5. Which structure in the kidney filters blood?

• A. Nephron
• B. Glomerulus
• C. Bowman's capsule
• D. Loop of Henle

Correct answer: B

Rationale: The correct answer is the Glomerulus. The glomerulus is a network of tiny blood vessels located within the Bowman's capsule. It acts as the initial filtering component in the nephron, filtering blood and allowing waste products and excess substances to pass through to form urine. Choice A, Nephron, is incorrect as the nephron is the structural and functional unit of the kidney composed of several parts, including the glomerulus. Choice C, Bowman's capsule, is where the glomerulus is located, but it is not the structure responsible for filtering blood. Choice D, Loop of Henle, plays a role in reabsorption of water and electrolytes but is not the primary structure for blood filtration in the kidney.
