1. When the genotype consists of a dominant and a recessive allele, the phenotype will be like the _ allele.

• A. Dominant
• B. Recessive
• C. Both
• D. Neither

Correct answer: A

Rationale: When the genotype consists of a dominant and a recessive allele, the phenotype will be like the dominant allele. This is because dominant alleles typically mask the expression of recessive alleles. Therefore, the dominant allele will be expressed in the phenotype in most basic cases. The recessive allele will only be expressed phenotypically if the individual is homozygous recessive. Choice B, 'Recessive,' is incorrect because the phenotype will not be like the recessive allele in this case. Choice C, 'Both,' is incorrect because in simple dominant-recessive inheritance, the dominant allele will overshadow the recessive allele. Choice D, 'Neither,' is incorrect as the phenotype will resemble the dominant allele.

2. Why does the diffusion rate increase as a substance is heated?

• A. The kinetic energy of particles increases.
• B. The space between particles increases.
• C. The density of particles decreases.
• D. The size of particles increases.

Correct answer: A

Rationale: The correct answer is A. When a substance is heated, the kinetic energy of particles increases, causing them to move faster. This increased movement allows the particles to spread out more rapidly, leading to a higher diffusion rate. Choice B is incorrect because heating does not directly affect the space between particles. Choice C is incorrect because heating does not necessarily lead to a decrease in the density of particles. Choice D is incorrect because the size of particles does not necessarily increase when a substance is heated. Therefore, the correct explanation for the increase in diffusion rate is the rise in kinetic energy of particles.

3. Which muscle in the shoulder is the deltoid?

• A. dendrite
• B. delphic
• C. deltoid
• D. dentate

Correct answer: C

Rationale: The deltoid muscle is located in the shoulder area. It is a rounded, triangular muscle that covers the shoulder joint and is responsible for lifting the arm and providing shoulder stability. The other options provided, dendrite, delphic, and dentate, are not muscles in the shoulder region.

4. Her guileless manner is one of her most noticeable qualities. What does guileless mean?

• A. Deceptive
• B. Straightforward
• C. Complex
• D. Untrustworthy

Correct answer: B

Rationale: The correct answer is B: 'Straightforward.' Guileless means innocent, sincere, and without deceit. It describes someone who is honest and straightforward in their actions and speech. Choices A, C, and D are incorrect. 'Deceptive' means misleading or dishonest, 'Complex' means having many intricate parts, and 'Untrustworthy' means not reliable or trustworthy, all of which are opposite in meaning to guileless.

5. What does it mean if a theory is obsolete?

• A. Advanced
• B. Outdated
• C. Useful
• D. Innovative

Correct answer: B

Rationale: If a theory is considered obsolete, it means that it is outdated and no longer in current use or practice. Choice A, 'Advanced,' is incorrect as it implies progression rather than obsolescence. Choice C, 'Useful,' is incorrect because an obsolete theory is no longer considered useful due to being outdated. Choice D, 'Innovative,' is incorrect as it suggests newness and originality, which are opposite to being obsolete.
