what percentage of cells is in
prophase?

Cells in prophase have an enlarged nucleus, the nucleolus is no longer visible, and the chromosomes appear as short jumbled strands within the nucleus. Cells spend about 14 percent of the cell cycle in prophase. This is the next largest amount of time spent in a phase after interphase.

14%

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.
