In a herd of 80 dairy cows 16 have black and whites coats and 64 have solid black coats. whaat is the frequency of cows with black and white coats

0.2

Explanation:

Total number of cows = 80

Black and white cows = 16

Frequency of black and white cows = Number of black and white cows / Total number of cows

= 16 / 80

= 0.2

or in percentage = 20%

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.
