Answer 1

B. Amino Acid

Step-by-step explanation:

The molecule shown in the picture is an amino acid, specifically serine. Amino acids are the building blocks of proteins and have a characteristic structure consisting of an amino group (-NH2), a carboxyl group (-COOH), and a side chain (R group) that varies depending on the specific amino acid. In the case of serine, the R group is a hydroxyl group (-OH), which is the functional group shown in the picture.

Answer 2

C. Carbohydrate
The given molecule consists of hydroxyl groups (-OH) attached to a carbon atom, making it a carbohydrate. Therefore, option C, Carbohydrate, is the correct answer.

Step-by-step explanation:

Carbohydrates are organic molecules consisting of carbon, hydrogen, and oxygen atoms. They are classified based on the number of sugar units they contain. Monosaccharides, such as glucose and fructose, contain a single sugar unit, while disaccharides, such as sucrose and lactose, contain two sugar units. Polysaccharides, such as starch and glycogen, contain many sugar units and are used for energy storage in plants and animals.
