English Grammar

1. Choose the correct pronoun to complete the sentence: "Neither Michael nor Sarah ____ their homework finished yet."

Correct answer: B

Rationale: When referring to "neither" followed by two subjects, the verb agrees with the plural subject ("Sarah"). So, "have" is the correct answer.

2. In a horizontal chart, the lowest level worker is located at the

Correct answer: B

Rationale: In a horizontal chart, the lowest level worker is typically positioned at the leftmost side, with higher-level workers placed to the right. This arrangement signifies hierarchy, with the top level usually being on the rightmost side. Therefore, the correct answer is B: 'Middle,' as the lowest level worker is situated towards the left of the chart, not the extreme left or right. This positioning helps visually represent the organization's structure and indicates the progression from lower to higher levels as one moves from left to right on the chart.

3. Which of the following is NOT a function of the cardiovascular system?

Correct answer: D

Rationale: The cardiovascular system is responsible for transporting oxygen to cells (option A), maintaining blood pressure (option B), and carrying waste products to the kidneys for removal (option C). However, initiating the immune response (option D) is not a function of the cardiovascular system. The immune response is primarily carried out by the immune system, which includes organs like the spleen and lymph nodes. While the cardiovascular system does play a role in immune function by transporting immune cells and antibodies, it is not responsible for initiating the immune response. Therefore, option D is the correct answer.

4. In the context of cholesterol levels, LDL cholesterol is often referred to as:

Correct answer: B

Rationale: The correct answer is B: LDL or "bad" cholesterol. LDL stands for low-density lipoprotein, which is often referred to as "bad" cholesterol because it can contribute to plaque buildup in the arteries, leading to a higher risk of heart disease. HDL, on the other hand, is known as "good" cholesterol because it helps remove LDL from the bloodstream. Total cholesterol (option C) encompasses both LDL and HDL levels but does not specifically refer to LDL cholesterol. VLDL (option D) is a different type of lipoprotein that transports triglycerides, not cholesterol. Understanding the distinction between LDL and HDL cholesterol is crucial for managing heart health.

5. The process of a gas changing directly into a solid is called:

Correct answer: B

Rationale: This process, also known as sublimation, involves gas particles losing energy and transitioning directly into the solid state.

6. The Hardy-Weinberg equilibrium describes a population that is:

Correct answer: B

Rationale: Rationale: The Hardy-Weinberg equilibrium describes a theoretical population in which allele frequencies remain constant from generation to generation, indicating that the population is not evolving. This equilibrium occurs under specific conditions: no mutation, no gene flow, random mating, a large population size, and no natural selection. In this scenario, all genotypes are in proportion to the allele frequencies, and genetic diversity is maintained. Options A, C, and D do not accurately describe a population in Hardy-Weinberg equilibrium. Option A suggests rapid evolution due to strong directional selection, which would disrupt the equilibrium. Option C mentions a founder effect, which can reduce genetic diversity but is not a characteristic of a population in Hardy-Weinberg equilibrium. Option D describes a population dominated by a single homozygous genotype, which also does not align with the genetic diversity seen in a population at Hardy-Weinberg equilibrium.
