1. What is the functional group present in ethers?

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

Correct answer: C

Rationale: Ethers have the functional group -O-, representing an oxygen atom bonded to two alkyl or aryl groups. The other choices are associated with different functional groups.

2. How is power defined in terms of physics?

• A. The rate at which work is done
• B. The amount of force applied
• C. The distance an object travels
• D. The potential energy of an object

Correct answer: a

Rationale: Power is defined as the rate at which work is done or the rate at which energy is transferred or converted.

3. Choose the correct pronoun to complete the sentence: "Neither Michael nor Sarah ____ their homework finished yet."

• A. has
• B. have
• C. are having
• D. does have

Correct answer: B

Rationale: When referring to "neither" followed by two subjects, the verb agrees with the plural subject ("Sarah"). So, "have" is the correct answer.

4. Which of the following functional groups is present in carboxylic acids?

• A. Carbonyl
• B. Hydroxyl
• C. Carboxyl
• D. Aldehyde

Correct answer: C

Rationale: Carboxylic acids contain the carboxyl functional group (-COOH). The other choices are associated with different functional groups.

5. A major factor influencing the distribution of organisms geographically is:

• A. The availability of specific types of food sources
• B. olerance of organisms to different temperature ranges
• C. Competition for mates within the same species
• D. All of the above

Correct answer: D

Rationale: Rationale: The distribution of organisms geographically is influenced by a variety of factors, including the availability of specific types of food sources (option A). Organisms need to have access to suitable food sources in order to survive and thrive in a particular area. Additionally, the tolerance of organisms to different temperature ranges (option B) is crucial as temperature can greatly impact where certain species can live. Organisms must be able to withstand the temperature conditions of a given environment to survive there. Competition for mates within the same species (option C) can also play a role in the distribution of organisms, as it can affect population sizes and dynamics in different areas. Therefore, all of these factors - food availability, temperature tolerance, and competition for mates - collectively influence the distribution of organisms geographically.

6. What is the pH value of a neutral solution?

• A. 0
• B. 7
• C. 14
• D. -7

Correct answer:

Rationale: A neutral solution has a pH of 7. The pH scale ranges from 0 to 14, with 7 being neutral.
