Answer:

30, 000 plaques.

Explanation:

Plaques may be defined as the clear zones or spots that indicates the lysis of the bacteriophages. These plaques are useful to count the number of progeny phages.

The formula used to calculate the phage is as follows;

Plaques progeny = [Number of plaques observe/(Dilution factor x Volume of diluted virus)]

Since, in the given question the dilution factor and volume is not given and it can be taken as unity.

Plaques progeny = 30, 000 / ( 1 x 1)

Plaques progeny =  30, 000.

Thus, the answer is 30, 000.

When you eat salmon for dinner, your digestive system will break down that food
zimovet [89]

Answer:   c. Amino Acids

Explanation:

Food is chemically and mechanically broken down into smaller particles like building blocks, the smallest of these are a basic unit called monomers. In the <em>stomach</em>, the enzyme pepsin breaks proteins, like those found in salmon, into smaller peptides by splitting the peptide bonds holding the proteins together. The <em>duodenum</em> processes these newly-formed peptide chains or polypeptides, into smaller ones, through the enzyme action of elastase, trypsin and chymotrypsin; these are produced in the pancreas. Peptidases convert these fragments into amino acid monomers for absorption into the bloodstream via the small intestines.
