1. Connective tissue provides support and connects other tissues. What is the main component that gives connective tissue its strength?
- A. Collagen fibers
- B. Epithelial cells
- C. Nerve cells
- D. Blood cells
Correct answer: A
Rationale: Collagen fibers are the main component that gives connective tissue its strength. Collagen is a fibrous protein that provides structural support and tensile strength to connective tissues, allowing them to withstand stretching and tension. Epithelial cells, nerve cells, and blood cells are not the main components responsible for the strength of connective tissue. Epithelial cells are specialized for covering and lining surfaces, nerve cells transmit signals, and blood cells are involved in various functions like oxygen transport and immune response, but they do not provide the structural strength typical of collagen fibers in connective tissue.
2. Which of the following is the base that will bind with cytosine?
- A. Adenine
- B. Cytosine
- C. Guanine
- D. Thymine
Correct answer: A
Rationale: Adenine is the correct answer as it is the base that binds with cytosine through hydrogen bonding in DNA, forming the A-T base pair. Cytosine always pairs with guanine to form the G-C base pair. Thymine pairs with adenine in DNA, not with cytosine.
3. Which of the following sentences uses figurative language?
- A. The scientist conducted an experiment.
- B. The child ran like a cheetah.
- C. The book contained many pages.
- D. The teacher explained the concept clearly.
Correct answer: B
Rationale: Choice B is the correct answer as it uses a simile, comparing the child's speed to that of a cheetah. Figurative language uses words or expressions with a meaning that is different from the literal interpretation, making the sentence more vivid and imaginative. In this case, the simile enhances the description of the child's speed by likening it to the swift and agile movement of a cheetah. Choices A, C, and D do not use figurative language. Option A is a straightforward statement about a scientist conducting an experiment without any figurative elements. Option C is a factual statement about a book having many pages without any figurative language. Option D is a clear explanation by a teacher without any figurative language present.
4. Which of the following is NOT a primary producer in an ecosystem?
- A. Grass
- B. Deer
- C. Algae
- D. Mushroom
Correct answer: B
Rationale: - A) Grass: Grass is a primary producer because it can photosynthesize and convert sunlight into energy, making it the base of the food chain. - B) Deer: Deer are consumers that feed on primary producers like grass, so they are not primary producers themselves. - C) Algae: Algae are primary producers that can photosynthesize and produce energy from sunlight. - D) Mushroom: Mushrooms are decomposers that break down organic matter, so they are not primary producers.
5. Identify the type of error in the sentence, 'They went to the store, bought groceries, then went home.'
- A. Run-on sentence
- B. Comma splice
- C. Dangling modifier
- D. Subject-verb agreement
Correct answer: A
Rationale: The given sentence combines multiple independent clauses without appropriate punctuation or conjunctions, creating a run-on sentence. A run-on sentence occurs when two or more independent clauses are joined without the necessary punctuation or coordination. In this case, the sentence lacks the proper conjunction or punctuation between 'store' and 'bought,' resulting in a run-on sentence. Choice B, 'Comma splice,' is incorrect because a comma splice involves joining two independent clauses with just a comma, which is not the case in the given sentence. Choice C, 'Dangling modifier,' is incorrect as there are no misplaced modifiers in the sentence. Choice D, 'Subject-verb agreement,' is also incorrect as the error in the sentence does not involve subject-verb agreement but rather the incorrect combination of independent clauses.
