Answer:
c. 20.
Explanation:
The answer is 20 because on 20 days, 7 colonies of Micro Yo occurs. The data of bacterial growth indicates that population of bacteria increases with the passage of time. This increase occurs due to good environmental conditions for bacteria that allows it to grow and increase their population. So we can say that the growth graph moves in the upward direction with the passage of time or number of days.

<h2><u>
Answer:</u></h2>
<u>Organic molecules:</u> are biologically important ones.All macro molecules are made up of simple molecules (monomers) that are bounded by specific bonds .Biologicaly important molecules are proteins ,fats ,carbohydrstes and nuclic acid.All these molecules are formed by condensation of monomers.
<u>proteins:</u> Proteins are made up polymers of amino acids. Aminoacids ae joined together by peptide bond.
A peptide bond is a chemical bond formed between two amino acid molecules when the carboxyl group of one molecule reacts with the amino group of the other molecule and releasing a molecule of water (H2O).
<u>Carbohydrates: </u> are biological important one are made up of monosaccharides and the are joined together by glycosidic bond.
<u>Fats:</u> are made up of fatty acids are joined together by covalent bonds called ester bond . Saturated fatty acids are bound by single anu unsaturated are made up of double or triple bonds.
<u>Nucleic acid:</u> are made up of nucleotides .Nucleotides are joined together by chemical bond called hydrogen bond.It is formed between the phosphate group of one nucleotide and the sugar of a neighboring nucleotide holds the backbone together.
