1. What is the medical term for an ingrown hair?

Correct answer: A

Rationale: The correct answer is A, Folliculitis. Folliculitis is the medical term for the inflammation of hair follicles, which can be caused by ingrown hairs. Hirsutism refers to excessive hair growth, pseudofolliculitis barbae is a condition where shaving causes ingrown hairs, and alopecia is hair loss. Therefore, choices B, C, and D are incorrect as they do not specifically refer to ingrown hairs.

2. In a scientific investigation, what is the first step?

Correct answer: C

Rationale: The correct answer is C: Formation of hypothesis. In a scientific investigation, forming a hypothesis is the initial step. A hypothesis is an educated guess or prediction based on existing knowledge and observations. It helps guide the experiment and provides a direction for the research process. Without a hypothesis, there is no specific aim or goal for the experiment. Choices A, B, and D are incorrect because they occur after the formation of a hypothesis. Analysis of results and drawing conclusions typically come after the experiment has been conducted, while performing the experiment is done to test the hypothesis formed at the beginning of the investigation.

3. Which of the following is NOT a mechanism that can directly cause evolution by natural selection?

Correct answer: C

Rationale: A) Mutations in genes can introduce new genetic variations into a population, which can be acted upon by natural selection. B) Differential survival and reproduction based on traits is a key component of natural selection, as individuals with advantageous traits are more likely to survive and pass on their genes to the next generation. C) Inheritance of acquired characteristics, also known as Lamarckism, is not a mechanism of evolution by natural selection. Traits acquired during an individual's lifetime (such as strong muscles from working out) are not passed on to offspring. D) Competition for resources in an environment can drive natural selection by favoring individuals with traits that help them better compete for limited resources. Therefore, the correct answer is C) Inheritance of acquired characteristics (like strong muscles from working out), as it is not a mechanism that can directly cause evolution by natural selection.

4. Which of the following is an example of a secondary alcohol?

Correct answer: C

Rationale: Isopropanol is indeed an example of a secondary alcohol because the carbon atom bearing the hydroxyl group is bonded to two other carbon atoms. In isopropanol, the hydroxyl group is attached to a carbon atom that is bonded to two other carbon atoms. Methanol (Choice A) is a primary alcohol with the hydroxyl group attached to a carbon atom that is bonded to one other carbon atom. Ethanol (Choice B) is also a primary alcohol with the hydroxyl group attached to a carbon atom that is bonded to one other carbon atom. Butanol (Choice D) is a primary alcohol with the hydroxyl group attached to a carbon atom that is bonded to three other carbon atoms, making it a primary alcohol.

5. Which of Mendel's Laws states that alleles for a gene segregate during gamete formation?

Correct answer: B

Rationale: The Law of Segregation, proposed by Gregor Mendel, states that alleles for a gene segregate during gamete formation. This means that each parent passes on only one allele for each gene to their offspring. This law explains how genetic diversity is maintained and how different combinations of alleles are generated in offspring. The Law of Independent Assortment (option A) is not the correct answer as it states that alleles of different genes assort independently of each other during gamete formation, not specifically alleles of a single gene. The Law of Dominance (option C) is incorrect as it pertains to the expression of alleles rather than their segregation during gamete formation. The Law of Probability (option D) is also incorrect as it is a general concept describing the likelihood of events, not specifically related to alleles segregating during gamete formation.
