1. The salesman recommended that he _____ his receipt for at least a month.

• A. keep
• B. keeps
• C. held
• D. saved

Correct answer: A

Rationale: The correct answer is 'keep.' In this context, the sentence is in the subjunctive mood, where the base form of the verb should be used after the word 'recommended.' Therefore, 'keep' is the appropriate verb choice. 'Keeps' (choice B) is incorrect as it does not align with the grammatical structure required in this sentence. Choices C and D are also incorrect as they do not match the verb form needed for the subjunctive mood.

2. If a test has poor internal consistency, which statement is true?

• A. The test produces different results at different times.
• B. The items do not correlate or measure similar things.
• C. The test produces different results depending on the researcher.
• D. The items never vary even when the test environment changes.

Correct answer: B

Rationale: Correct answer: If a test has poor internal consistency, it means that the items do not correlate or measure similar things. This lack of correlation indicates that the items in the test are not measuring the same underlying construct or concept, leading to unreliable results. Choice A is incorrect because poor internal consistency is not about producing different results at different times but rather about the lack of correlation among items. Choice C is incorrect because the issue lies within the test itself, not with different researchers. Choice D is incorrect because poor internal consistency implies that the items do vary in their measurement, contributing to the unreliability of the test.

3. Why does cytokinesis happen?

• A. DNA can duplicate
• B. Organelles can convert energy
• C. Bacteria can be killed
• D. Daughter cells can divide

Correct answer: D

Rationale: Cytokinesis happens at the end of mitosis to physically separate the newly formed daughter cells. This allows the cell to divide into two separate daughter cells, each containing a complete set of genetic material (DNA) and organelles. The purpose of cytokinesis is to ensure that each daughter cell receives the necessary components to function independently. Choices A, B, and C are incorrect because cytokinesis does not directly involve DNA duplication, organelles converting energy, or killing bacteria.

4. Which is true of the term Phenotype?

• A. It is the genetic code
• B. Phenotype determines genotype
• C. Genotype determines phenotype
• D. Genotype, epigenetic factors, and environmental factors determine phenotype

Correct answer: D

Rationale: The term "phenotype" refers to the observable characteristics or traits of an organism, which are determined by a combination of genotype (genetic makeup), epigenetic factors (modifications to gene expression), and environmental factors (external influences and experiences). Genotype, epigenetic factors, and environmental factors all play a role in determining an individual's phenotype, making option D the correct statement. Options A, B, and C are incorrect because the phenotype is not the genetic code, the phenotype does not determine the genotype, and it is the genotype that influences the phenotype, not the other way around.

5. Which component of the cell contributes to the protection, communication, and passage of substances into and out of the cell?

• A. Nucleus
• B. Cell membrane
• C. Endoplasmic reticulum
• D. Cytoplasm

Correct answer: B

Rationale: The correct answer is the cell membrane. The cell membrane is responsible for protecting the cell, facilitating communication with the external environment, and regulating the passage of substances into and out of the cell. The nucleus (Choice A) is the control center of the cell and houses the genetic material but is not primarily involved in these functions. The endoplasmic reticulum (Choice C) is involved in protein synthesis and lipid metabolism, not primarily in protection or communication. The cytoplasm (Choice D) is the gel-like substance that fills the cell but does not specifically contribute to protection, communication, or substance passage.
