1. What functional group is present in ethers?

• A. Hydroxyl
• B. Carbonyl
• C. Ether
• D. Amine

Correct answer: C

Rationale: The functional group present in ethers is -O-, representing an oxygen atom bonded to two alkyl or aryl groups. Therefore, choice C, 'Ether,' is the correct answer. Choices A, B, and D refer to different functional groups: hydroxyl (-OH), carbonyl (C=O), and amine (NH2), respectively, which are not present in ethers. Ethers are characterized by the oxygen atom bonded to two carbon groups, distinguishing them from the other functional groups mentioned in the choices.

2. What part of speech is the word 'growing' in the sentence: 'He felt a growing sense of unease'?

• A. Verb
• B. Adjective
• C. Noun
• D. Adverb

Correct answer: B

Rationale: The word 'growing' in the sentence 'He felt a growing sense of unease' is functioning as an adjective. It describes the sense of unease, indicating a characteristic of the sense rather than an action (verb), a person, place, thing, or idea (noun), or modifying a verb, an adjective, or another adverb (adverb). Therefore, 'growing' is an adjective in this context.

3. Which of the following transitional words or phrases can be used to indicate contrast? (Select all that apply.)

• A. Regardless
• B. Furthermore
• C. On the other hand
• D. Moreover

Correct answer: A, C

Rationale: The correct transitional words or phrases that indicate contrast are 'Regardless' and 'On the other hand.' 'Regardless' introduces a contrasting idea, while 'On the other hand' explicitly signals a shift in perspective or introduces an opposing viewpoint. 'Furthermore' and 'Moreover' are not used to indicate contrast; instead, they are used to add more information or support to a related point.

4. 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: Autosomal dominant inheritance results in a 3:1 ratio of dominant to recessive phenotypes in the F2 generation. This inheritance pattern occurs when a single copy of the dominant allele is enough to express the dominant phenotype. A) Incomplete dominance: In incomplete dominance, the heterozygous phenotype is a blend of the two homozygous phenotypes, and it does not lead to 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, but this pattern 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 lead to a 3:1 ratio of dominant to recessive phenotypes in the F2 generation.

5. Julie Walker-Mayfield plans to register for fall classes at Chatham College. She works during the day and doesn't get off work until 5:30 PM. She also has no internet access at work and will have to register for classes once she gets home. Taking into account her personal schedule and the registration schedule provided by the college, when will she be able to go online to enter the registration system and select her classes?

• A. Monday, 10 AM-12 PM
• B. Monday, 5-7 PM
• C. Tuesday, 5-7 PM
• D. Tuesday, 8-10 PM

Correct answer: C

Rationale: Julie Walker-Mayfield doesn't get off work until 5:30 PM, so she won't be able to register for classes until she gets home. Considering she needs time to unwind after work and settle in, the earliest and most suitable time for her to enter the registration system and select her classes is Tuesday, 5-7 PM. Choice A is incorrect as it falls on Monday, and she gets off work at 5:30 PM. Choices B and D are also incorrect as she needs time to settle in after work before going online to register.
