Answer:

D

Explanation:

The building blocks or monomers of proteins are called amino acids. There are 20 different kinds of amino acids. The amino acids form long chains that are proteins. Therefore, proteins are polymers of amino acids.

Proteins are very important for the body because they have many different roles. They provide structure for tissues, act as enzymes, hormones and antibodies, aid in transportation and fluid regulation.

Therefore, the correct answer is D. a polymer of amino acids.

Artist 52 [7]

Answer:

2,2,4-trimethylpentane has the higher heat of combustion in kcal/mol.

Explanation:

Heat of combustion is defined as heat evolved on combustion of 1 mole of a substance.

2,2,4-trimethylpentane has the higher heat of combustion in kcal/mol.

Heat combustion of 2,2,4-trimethylpentane =  (1304 kcal/mol) and

C_8H_{18}+\frac{25}{2}O_2\rightarrow 8CO_2+9H_2O,\Delta H=-1,304 kcal/mol

1 mole of 2,2,4-trimethylpentane on combustion gives 8 mole sof carbon dioxide gas and 9 moles of water.

Heat combustion of ethanol = (327 kcal/mol)

C_2H_5OH+3O_2\rightarrow 2CO_2+3H_2O,\Delta H=-327kcal/mol

1 mole of ethanol on combustion gives 2 moles of carbon dioxide gas and 3 mole of water.

Heat combustion of ethanol < Heat combustion of 2,2,4-trimethylpentane
