Answer the following question given this paragraph: A ketone involves a carbonyl in which the carbon atom makes single bonds with two other carbon atoms. Ketones undergo most of the same reactions as aldehydes, but they tend to be slightly less reactive. The simplest ketone is acetone, in which the carbonyl carbon is bonded to two CH 3 groups. This ketone is commonly used to remove fingernail polish and serves as an industrial solvent. Methyl ethyl ketone is used as a paint stripper and a solvent. Ketones are also used in the production of various polymers, either as a building block or as a solvent. Q: Acetone is the simplest type of what organic compound that involves a carbonyl in which the carbon atom makes single bonds with two other carbon atoms? A:
OPTIONS:
- enzyme
- protein
- anion
- ketone

Answer the following question given this paragraph: Most prokaryotes have a peptidoglycan cell wall and many have a polysaccharide capsule (Figure 4.5). The cell wall acts as an extra layer of protection, helps the cell maintain its shape, and prevents dehydration. The capsule enables the cell to attach to surfaces in its environment. Some prokaryotes have flagella, pili, or fimbriae. Flagella are used for locomotion. Pili are used to exchange genetic material during a type of reproduction called conjugation. Fimbriae are used by bacteria to attach to a host cell. Q: The cell wall acts as an extra layer of protection, helps the cell maintain its shape, and prevents what? A:
OPTIONS:
- extinction
- exhaustion
- Respiration
- dehydration
dehydration

Q: A species is a subdivision of a genus in what classification system? A:
OPTIONS:
- calcareous system
- mammalian
- crocodilian system
