1. What is the difference between a homozygous recessive genotype and a homozygous dominant genotype?

• A. Both have the same phenotype, but different genotypes.
• B. Both have the same genotype, but different phenotypes.
• C. Homozygous recessive has two dominant alleles, while homozygous dominant has two recessive alleles.
• D. Homozygous recessive has two identical recessive alleles, while homozygous dominant has two identical dominant alleles.

Correct answer: D

Rationale: - Homozygous recessive genotype refers to an individual having two identical recessive alleles for a particular gene (e.g., rr for a trait where r represents the recessive allele). - Homozygous dominant genotype refers to an individual having two identical dominant alleles for a particular gene (e.g., RR for a trait where R represents the dominant allele). - The difference between the two genotypes lies in the specific alleles present in each case, with homozygous recessive having two recessive alleles and homozygous dominant having two dominant alleles. - This genetic difference results in different phenotypes being expressed, as the dominant allele typically masks the expression of the recessive allele in heterozygous individuals.

2. Which of the following sentences correctly uses commas to set off a non-essential element?

• A. The teacher, who lives next door, will visit our class next week.
• B. The teacher who lives next door will visit our class next week.
• C. The teacher, who, by the way, lives next door, will visit our class next week.
• D. The teacher will visit our class next week, who lives next door.

Correct answer: A

Rationale: The correct answer is A. In this sentence, the phrase 'who lives next door' is a non-essential element providing additional information about the teacher. It is correctly set off by commas. Choice B does not use any commas to set off the non-essential element, making the information essential to the sentence. Choice C uses an unnecessary comma before 'who,' which disrupts the flow of the sentence. Choice D incorrectly places the non-essential element at the end of the sentence without appropriate commas, making it less clear and concise.

3. Which sentence uses the pronoun 'they' correctly?

• A. They is going to the park later today.
• B. Sarah and John said they would come to the party.
• C. The teacher said they needs to finish the report.
• D. They enjoys reading books in their free time.

Correct answer: B

Rationale: A. "They" should be used with "are," not "is." B. Correct use of "they" for multiple people (Sarah and John). C. "They" should not be paired with "needs." D. "They" should be used with "enjoy," not "enjoys."

4. How many milliliters are in 1.5 liters?

• A. 15 mL
• B. 1,500 mL
• C. 150 mL
• D. 150,000 mL

Correct answer: B

Rationale: To convert liters to milliliters, you need to multiply by 1,000 since there are 1,000 milliliters in a liter. Therefore, 1.5 liters x 1,000 = 1,500 milliliters. Choice A, 15 mL, is incorrect as it represents the conversion of 0.015 liters. Choice C, 150 mL, is incorrect as it represents the conversion of 0.15 liters. Choice D, 150,000 mL, is incorrect as it represents the conversion of 150 liters.

5. Identify the type of clause in the sentence: 'I ate, and he drank.'

• A. Coordinate clause
• B. Dependent clause
• C. Subordinate clause
• D. Independent clause

Correct answer: A

Rationale: The correct answer is 'A: Coordinate clause.' In the sentence 'I ate, and he drank,' 'I ate' and 'he drank' are coordinate clauses. They are both independent clauses that are joined by the coordinating conjunction 'and.' A coordinate clause is a type of independent clause that is equally important and balanced within a sentence. A dependent clause cannot stand alone as a complete sentence and relies on an independent clause. A subordinate clause is a type of dependent clause that functions within a sentence to provide additional information but does not express a complete thought. An independent clause, on the other hand, can stand alone as a complete sentence.
