The activity of the enzyme β-galactosidase produced by wild-type cells grown in media supplemented with different carbon sources is measured. in relative units, the levels of activity of βgalactosidase is given for the wild-type. predict the relative levels of β-galactosidase activity in cells grown under the same condition in following mutant cells.

I am assuming that the mutant cells have mutated beta galactosidase activity hence the relative levels of enzymatic activity would be reduced.

white blood cells or wbc s are mainly 2 types-

1.agranulocytes

2.granulocytes

the monocytes or macrophages of agranulocytes , dendritic cells which are accessory leucocytes, and b cells which is one type of lymphocytes   identify the antigens present on the pathogen's surface. these three cells are called antigen presenting cells(apc) which are phagocytes and destroy the antigens by secreting antitoxins. besides this leukocyte is always plays vital role in the immunity of the body.
