1. Which of the following sentences correctly uses a transition word?

• A. Gilda is a hardworking student; therefore, she earned a good grade on her essay.
• B. Gilda is a hardworking student; therefore she earned a good grade on her essay.
• C. Gilda is a hardworking student: therefore, she earned a good grade on her essay.
• D. Gilda is a hardworking student and therefore she earned a good grade on her essay.

Correct answer: A

Rationale: Choice A is the correct answer. 'Therefore' is correctly used as a transition word with proper punctuation in this sentence. In a compound sentence like this, a semicolon is used before the transition word to connect two independent clauses. Choice B is incorrect because it lacks the necessary punctuation to separate the independent clauses. Choice C is incorrect as a colon is not typically used before a transition word in this context. Choice D is incorrect because 'and' does not function as a transition word in this sentence.

2. Which of the following sentences supports the thesis statement: 'Organic gardening can be as simple or complex as you choose to make it'?

• A. Organic gardening ranges from basic composting to a chemical analysis of the soil.
• B. Organic gardening is easy.
• C. Gardening is fun for everyone.
• D. Organic foods are better for health.

Correct answer: A

Rationale: Choice A is the correct answer because it directly supports the thesis statement by illustrating the wide spectrum of complexity within organic gardening, from basic practices like composting to more advanced techniques like soil chemical analysis. This range of possibilities aligns with the idea that organic gardening can be as simple or as complex as one chooses to make it. Choices B, C, and D do not directly relate to the flexibility and complexity aspect of organic gardening as emphasized in the thesis statement. Choice B oversimplifies the process, choice C focuses on the enjoyment of gardening in general rather than the complexity of organic gardening, and choice D discusses the health benefits of organic foods, which is not directly related to the range of options within organic gardening.

3. Which of the following immune cells are part of the innate immune response?

• A. B-cells
• B. Cytotoxic T-cells
• C. Natural Killer cells
• D. Antigen-Presenting Cells

Correct answer: C

Rationale: Natural Killer cells are a crucial component of the innate immune response. They play a significant role in defending against infected or cancerous cells through their ability to identify and kill abnormal cells. B-cells (Choice A) and Cytotoxic T-cells (Choice B) are part of the adaptive immune response, which involves a more specific and targeted response to pathogens. Antigen-Presenting Cells (Choice D) are also part of the adaptive immune response, where they present antigens to activate other immune cells.

4. When unpolarized light passes through a polarizing filter, the intensity of the transmitted light is:

• A. Completely absorbed
• B. Reduced by half
• C. Unaffected
• D. Doubled

Correct answer: B

Rationale: When unpolarized light passes through a polarizing filter, the filter only allows light waves oscillating in a specific direction to pass through while blocking light waves oscillating in other directions. Since unpolarized light consists of light waves oscillating in all possible directions, when it passes through a polarizing filter, only half of the light waves (those oscillating in the direction allowed by the filter) are transmitted. As a result, the intensity of the transmitted light is reduced by half. Choice A is incorrect because the light is not completely absorbed; choice C is incorrect because the polarizing filter affects the transmitted light; and choice D is incorrect because the intensity does not double, but rather decreases by half due to the selective transmission of light waves in a specific direction by the polarizing filter.

5. Which organelle is responsible for storing genetic material?

• A. Mitochondria
• B. Nucleus
• C. Ribosome
• D. Endoplasmic reticulum

Correct answer: B

Rationale: The correct answer is the Nucleus. The nucleus is responsible for storing genetic material (DNA) and controlling cell functions. Mitochondria are known for energy production, not genetic storage. Ribosomes are involved in protein synthesis, not genetic material storage. The endoplasmic reticulum is involved in protein and lipid synthesis, not genetic material storage. Therefore, the nucleus is the organelle primarily responsible for housing the genetic material within a cell.
