English Grammar

1. What is the main verb tense in the following sentence? "She had already left before I arrived."

Correct answer: D

Rationale: The verb "had left" is in the past perfect tense, indicating an action completed before another past action ("arrived").

2. Which of the following is NOT a common symptom of pregnancy?

Correct answer: D

Rationale: The correct answer is D: "Loss of appetite." While it is common for pregnant individuals to experience fatigue, nausea, and increased urination due to hormonal changes and the body's adaptations during pregnancy, a loss of appetite is not typically a common symptom. Most pregnant individuals experience increased appetite, particularly in the early stages of pregnancy. This increased appetite is often attributed to the body's need for additional nutrients to support the growing fetus. Therefore, the absence of appetite loss makes option D the correct choice in this question.

3. During antibiotic use, bacteria can evolve resistance. This is an example of:

Correct answer: D

Rationale: Rationale: - Coevolution (option A) refers to the influence of two species on each other's evolution, which is not the case in the scenario described in the question. - Convergent evolution (option B) involves unrelated organisms evolving similar traits due to similar environmental pressures, which is not directly applicable to the situation of bacteria evolving resistance to antibiotics. - Macroevolution (option C) refers to large-scale evolutionary changes over long periods, which is not specifically demonstrated in the context of bacteria evolving resistance during antibiotic use. - The process of bacteria evolving resistance to antibiotics due to the selective pressure exerted by the antibiotics is an example of artificial selection (human intervention selecting for certain traits) acting on a natural process (bacterial evolution). Antibiotic use creates a selective pressure that favors the survival and reproduction of bacteria with resistance traits, leading to the evolution of an

4. What is the primary function of hair on the human body?

Correct answer: A

Rationale: The primary function of hair on the human body is insulation. Hair acts as a protective layer to help regulate body temperature by trapping heat close to the skin. This insulation property is especially important in colder climates to prevent excessive heat loss from the body. While hair can also provide some level of protection from external elements and minor injuries, its main role is to insulate the body. Sensory perception is mainly attributed to nerve endings in the skin rather than hair. Vitamin D synthesis is primarily dependent on exposure to sunlight rather than hair. Therefore, option A, insulation, is the correct answer.

5. What is the main function of the endoplasmic reticulum (ER) in the cell?

Correct answer: A

Rationale: Rationale: A) The endoplasmic reticulum (ER) is a network of membranes within the cell that plays a crucial role in protein and lipid synthesis. It consists of two types: rough ER, which is studded with ribosomes and involved in protein synthesis, and smooth ER, which is involved in lipid synthesis and detoxification. The ER also plays a role in transporting these synthesized proteins and lipids to other parts of the cell or outside the cell. B) While the ER is involved in packaging proteins, the main function is not solely to package and transport proteins. This function is more associated with the Golgi apparatus. C) Breaking down macromolecules is primarily the function of lysosomes, which are membrane-bound organelles containing enzymes for digestion. D) Storing genetic material is the function of the nucleus, which houses the cell's DNA. The ER is not involved in storing

6. Which of the following is a characteristic of a solution with a high viscosity?

Correct answer: c

Rationale: Solutions with high viscosity have a high resistance to flow. The other choices do not accurately describe high viscosity.
