1. Which of the following best describes the statement 'This flower is dead; someone must have forgotten to water it'?

Correct answer: C

Rationale: The correct answer is 'C: An inference.' An inference is a conclusion reached based on evidence and reasoning. In this statement, the conclusion that someone must have forgotten to water the flower is drawn from the evidence that the flower is dead. Choice A, 'A classification,' is incorrect because the statement does not involve categorizing or grouping. Choice B, 'An observation,' is incorrect as the statement goes beyond just stating a fact and makes a conclusion. Choice D, 'A collection,' is unrelated to the process of drawing a conclusion based on the given evidence.

2. What does potency refer to in regards to cells?

Correct answer: D

Rationale: Potency refers to a cell's potential to differentiate into different cell types. It is not related to the cell's ability to survive (Choice A), move (Choice B), or divide rapidly (Choice C). Stem cells, for example, exhibit varying degrees of potency based on their capacity to give rise to various cell types. Therefore, the correct answer is D as it accurately defines the concept of potency in cells.

3. What property of matter determines its resistance to changes in shape or size?

Correct answer: A

Rationale: The correct answer is 'Solid.' Solids have a definite shape and volume, providing them with a strong resistance to changes in shape or size. Liquids and gases do not have a definite shape, making them prone to changing shape or size easily. Plasmas, on the other hand, are ionized gases with high energy levels and lack a definite shape or volume, which does not contribute to resistance against changes in shape or size. Therefore, the properties of solids make them best suited for resisting changes in shape or size compared to liquids, gases, and plasmas.

4. Acids are generally characterized by a sour taste and the ability to:

Correct answer: C

Rationale: Acids are known for their sour taste and their ability to neutralize bases, which is a defining characteristic of their acidic nature. When acids neutralize bases, salts and water are formed, highlighting the unique property of acids. The other options are incorrect: Option A, 'Turn litmus paper red,' is a test for acidity but not a defining characteristic of acids; Option B, 'Conduct electricity in solution,' pertains to the electrolytic properties of acids rather than their defining trait; Option D, 'React explosively with metals,' is not a general characteristic of acids. Therefore, the correct feature associated with acids is their capability to neutralize bases, making option C, 'Neutralize bases,' the correct answer.

5. What is the term for an organism with two different alleles for a gene?

Correct answer: B

Rationale: Homozygous refers to an organism with two identical alleles for a gene, either both dominant or both recessive. Heterozygous, the correct answer, refers to an organism with two different alleles for a gene, one dominant and one recessive. Dominant and recessive describe the relationship between alleles, where dominant alleles are expressed over recessive alleles in heterozygous individuals. Therefore, the term for an organism with two different alleles for a gene is 'heterozygous.'
