The smallest unit of life is the best that describes a living cell.

Explanation:

The cells are the smallest unit of living thing. A living thing is composed of one cell or more cells are known as organism. All living organisms are made up of cells they are the structural unit of organization.

The organisms that are made up of one cell is known as unicellular and the organisms that are made up of multiple cells are known as multicellular. Each and every organisms need energy to survive.

The group of similar cells combine and perform specific function is known as tissues.

they are known to reach a speed of 21 miles per hour

carbohydrates: (starches and sugars) composed of carbon, hydrogen, and oxygen.

lipids: (fats, oils, and waxes) are made of carbon and hydrogen atoms.

nucleic acids: contain hydrogen, oxygen, nitrogen, carbon, and phosphorus. they are polymers of nucleotides. a nucleotide has three parts, a 5-carbon sugar, a phosphate     (-po⬇️4) group, and a nitrogenous base.

proteins: made up of nitrogen, carbon, hydrogen, and oxygen. they are polymers of amino acids.
