1. Are red hair and a height of six feet part of an individual's genotype or phenotype?

A. Red hair is part of the phenotype; height is part of the genotype.
B. Red hair is part of the genotype; height is part of the phenotype.
C. Both characteristics describe his genotype.
D. Both characteristics describe his phenotype.

Correct answer: D

Rationale: In the context of genetics, genotype refers to an individual's genetic makeup, while phenotype refers to the observable characteristics resulting from the interaction of the genotype with the environment. Red hair and a height of six feet are observable characteristics, making them part of the individual's phenotype. Therefore, both red hair and height are aspects of the individual's phenotype. Choices A and B are incorrect as they incorrectly assign one characteristic to the genotype and the other to the phenotype, which is not accurate. Choice C is incorrect as it states that both characteristics describe the genotype, which is inaccurate as they are observable traits. The correct answer is D, as both red hair and height are observable traits or characteristics, falling under the definition of phenotype in genetics.

2. What type of immunity does a vaccine provide? Choose only ONE best answer.

A. Naturally acquired passive immunity
B. Artificially acquired passive immunity
C. Naturally acquired active immunity
D. Artificially acquired active immunity

Correct answer: D

Rationale: The correct answer is D: Artificially acquired active immunity. Vaccines work by stimulating the immune system to produce an active response, leading to the development of immunity against specific pathogens. Choice A, naturally acquired passive immunity, is incorrect as it refers to the temporary immunity passed from mother to child, not through vaccines. Choice B, artificially acquired passive immunity, is also incorrect because passive immunity involves the transfer of pre-formed antibodies, not the stimulation of the immune system by vaccines. Choice C, naturally acquired active immunity, is incorrect since it is acquired through natural exposure to pathogens, not through vaccines.

3. A spring with a spring constant of 100 N/m is stretched 0.2 m from its equilibrium position. What is the potential energy stored in the spring?

A. 2 J
B. 4 J
C. 8 J
D. 20 J

Correct answer: C

Rationale: The potential energy stored in a spring is given by the formula $PE = \frac{1}{2}kx^2$, where $k$ is the spring constant and $x$ is the displacement from the equilibrium position. Substituting the given values, we get $PE = \frac{1}{2} \times 100 \times (0.2)^2 = 8$ J.

4. What is the general formula for an alkene?

A. CnH2n+2
B. CnH2n
C. CnH2n-2
D. CnH2n+1

Correct answer: B

Rationale: The general formula for an alkene is $C_nH_{2n}$, indicating the presence of a double bond between carbon atoms.

5. Which of the following is NOT a state of matter?

A. Solid
B. Liquid
C. Gas
D. Superfluid

Correct answer: D

Rationale: The correct answer is 'Superfluid.' Superfluid is not considered a traditional state of matter. It is a unique phase of matter that displays zero viscosity and flows without losing kinetic energy. Solids, liquids, and gases are the three classical states of matter distinguished by their physical properties and structures. Therefore, choices A, B, and C are considered states of matter, while choice D, superfluid, is not.
