1. If an organism is AB, which of the following combinations in the gametes is NOT possible?

• A. AB
• B. AA
• C. BB
• D. AB

Correct answer: B

Rationale: The correct answer is B. If an organism is AB, it indicates that it carries two different alleles. During gamete formation, each gamete receives only one allele from the pair present in the organism. Therefore, in this case, the possible gametes would be 'A' and 'B,' making 'AA' impossible. Choice A, 'AB,' is possible as each gamete can carry one of the alleles from the genotype. Similarly, 'BB' is also possible if one of the alleles separates into a gamete. Choice D, 'AB,' is essentially the same genotype as the organism and is a possible combination in the gametes.

2. The scatter plot below shows the relationship between the students' exam scores and their heights. Which type of correlation is depicted in the scatter plot?

• A. Positive
• B. Positive and Negative
• C. Negative
• D. No correlation

Correct answer: D

Rationale: The scatter plot illustrates the relationship between students' exam scores and heights. There is no correlation between these variables, as height is not expected to have a direct impact on exam scores. Therefore, choice D, 'No correlation,' is the correct answer. Choices A, 'Positive,' and C, 'Negative,' are incorrect because the scatter plot does not indicate a positive or negative correlation between exam scores and heights. Choice B, 'Positive and Negative,' is also incorrect because the scatter plot does not exhibit both positive and negative correlations simultaneously.

3. Wow, what an amazing shot to win the game!

• A. Comma
• B. Exclamation mark
• C. Semicolon
• D. Question mark

Correct answer: B

Rationale: The correct answer is an exclamation mark because it is used to convey strong emotion or excitement, which is appropriate for the sentence. A comma is not suitable here as it does not convey the level of excitement expressed in the sentence. A semicolon is used to join independent clauses or separate items in a list, which is not required in this context. A question mark would be incorrect as the statement is not a question but rather an expression of excitement.

4. What are organisms that break down dead organisms and return nutrients to the environment called?

• A. Producers
• B. Decomposers
• C. Consumers
• D. Parasites

Correct answer: B

Rationale: Decomposers are essential organisms in the ecosystem as they break down dead organisms and organic matter, such as bacteria, fungi, and some insects. By decomposing complex organic materials into simpler forms, they release nutrients back into the environment for other organisms to utilize. Producers (option A) are organisms that generate their own food through photosynthesis; consumers (option C) are organisms that feed on other organisms for energy, and parasites (option D) are organisms that live on or in another organism, benefiting at the host's expense rather than breaking down dead organisms for nutrient recycling.

5. Based on his work and goals, how should the sentence 'Fred Hampton desired to see lasting social change for African Americans through nonviolent means and community recognition.' be best introduced?

• A. NO CHANGE
• B. Unfortunately,
• C. Finally,
• D. As a result,

Correct answer: D

Rationale: The correct answer is 'D: As a result.' This choice effectively ties Hampton's desire for social change to his ongoing efforts and achievements. 'As a result' indicates a logical connection between Hampton's aspirations and the actions he took to achieve them. Choices B, C, and A are incorrect because they do not provide a suitable transition that connects Hampton's goals with his actions or achievements. 'Unfortunately' (choice B) introduces a negative connotation that is not appropriate in this context. 'Finally' (choice C) suggests a chronological sequence rather than a cause-and-effect relationship. 'NO CHANGE' (choice A) does not establish a clear link between Hampton's desires and his efforts for social change.
