1. What property of a substance remains constant regardless of changes in its location in the universe?

• A. Mass
• B. Weight
• C. Density
• D. Volume

Correct answer: a

Rationale: Mass is an intrinsic property of matter and remains constant regardless of its location.

2. What type of inheritance pattern results in a 3:1 ratio of dominant to recessive phenotypes in the F2 generation?

• A. Incomplete dominance
• B. Codominance
• C. Sex-linked inheritance
• D. Autosomal dominant inheritance

Correct answer: D

Rationale: Rationale: A) Incomplete dominance: In incomplete dominance, the heterozygous phenotype is a blend of the two homozygous phenotypes. This does not result in a 3:1 ratio of dominant to recessive phenotypes in the F2 generation. B) Codominance: In codominance, both alleles are fully expressed in the heterozygous phenotype. This also does not result in a 3:1 ratio of dominant to recessive phenotypes in the F2 generation. C) Sex-linked inheritance: Sex-linked inheritance involves genes located on the sex chromosomes and does not typically result in a 3:1 ratio of dominant to recessive phenotypes in the F2 generation. D) Autosomal dominant inheritance: In autosomal dominant inheritance, a single copy of the dominant allele is sufficient to express the dominant phenotype. When a heterozygous individual (Aa) is crossed with another

3. When proofreading your writing, focus on:

• A. Changing the wording to sound more original.
• B. Ignoring minor grammatical errors like typos.
• C. Checking for clarity, consistency, and overall flow.
• D. Replacing common words with thesaurus alternatives.

Correct answer: C

Rationale: Proofreading involves correcting errors, refining sentence structure, and ensuring the writing achieves its purpose, clarity, and consistency.

4. The process of a gas changing directly into a solid is called:

• A. Condensation
• B. Deposition
• C. Sublimation
• D. Evaporation

Correct answer: B

Rationale: This process, also known as sublimation, involves gas particles losing energy and transitioning directly into the solid state.

5. Lymph nodes, found along lymphatic vessels, are important for:

• A. Storing blood
• B. Producing antibodies
• C. Filtering lymph and trapping harmful substances
• D. All of the above

Correct answer: D

Rationale: The correct answer is D, 'All of the above.' Lymph nodes are important for various functions in the immune system. They filter lymph, trapping harmful substances like bacteria and viruses, which helps in preventing infections. Lymph nodes also play a crucial role in producing antibodies, which are essential for fighting off pathogens. Additionally, lymph nodes do not store blood; that is the function of the spleen. Therefore, the correct answer is D because lymph nodes perform all the mentioned functions in supporting the body's immune response.

6. Which of the following describes a vector quantity?

• A. Speed
• B. Distance
• C. Mass
• D. Velocity

Correct answer: d

Rationale: Velocity is a vector quantity as it includes both magnitude (speed) and direction.
