Answer the following question given this paragraph: Because carbohydrates have a carbonyl functional group and several hydroxyl groups, they can undergo a variety of biochemically important reactions. The carbonyl group, for example, can be oxidized to form a carboxylic acid or reduced to form an alcohol. The hydroxyl groups can undergo substitution reactions, resulting in derivatives of the original compound. One such derivative is Sucralose, an artificial sweetener that is six times sweeter than sucrose; it is made by replacing two of the hydroxyl groups on sucrose with chlorine. Carbohydrates can also eliminate hydroxyl groups, producing alkenes. Q: Because carbohydrates have a carbonyl functional group and several hydroxyl groups, they can undergo a variety of biochemically important reactions. the carbonyl group, for example, can be oxidized to form a carboxylic acid or reduced to form this? A:

OPTIONS:
- glucose
- sucrose
- caffeine
- alcohol

Answer: alcohol

Answer the following question given this paragraph: All vertebrate organisms are in the phylum Chordata. Invertebrates, which make up about 95% (or more) of the animal kingdom, are divided into over 30 different phyla, some of which are listed below ( Table below ). Numerous invertebrate phyla have just a few species; some have only one described species, yet these are classified into separate phyla because of their unique characteristics. For example, sponges, with pores throughout their body, are from the phylum Porifera. Crabs and lobsters, with jointed appendages, are from the phylum Arthropoda. Q: Which phylum are all vertebrate organisms a member of? A:

OPTIONS:
- pylum protozoa
- phylum hominid
- phylum arthropod
- phylum chordata

Answer: phylum chordata
