There are 27 x 10⁷ cells in total for the given conditions of cell culture.
Since it is given that the cell culture contains 3 x 10⁵ cells per ml and there are 12 culture flasks in total. It is also given that each of the culture flask holds 75 ml of culture.
Therefore, to calculate the total capacity of the flasks the total number of flasks should be multiplied with the individual capacity of a flask:-
75 x 12 = 900 ml
Now, in order to calculate the total number of cells in the given culture., the total capacity of the flasks i.e. 900 ml should be multiplied with 3 x 10⁵ cells per ml in the following manner:-
900 x (3 x 10⁵) = 2700 x 10⁵ = 27 x 10⁷ cells

● The method of "<em><u> </u></em><em><u>one-way</u></em><em><u> </u></em><em><u>analysis</u></em><em><u> </u></em><em><u>of</u></em><em><u> </u></em><em><u>variance</u></em><em><u> </u></em><em><u>"</u></em> is used for tests of hypotheses that three or more population means are equal.
Answer:
A decrease in pH is too acidic compared to optimum pH for amylase activity. The hydrogen ion changes amylase sites of activity and amylase activity become low. At pH 13 to 1 which is acidic, reduces the activity of amylase because the hydrogen ion changes amylase activity sites and render it's action low which will denatures amylase and make it ineffective.
Explanation:
Amylase refer to enzymes that catalyses or breakdown starch into sugars. General, enzymes are biological substances that speed up the rate of chemical reactions.
Enzymes generally are affected by pH. The most favorable pH is the optimum pH which make amylase to be effective or enzymes.
A high pH or low pH has effect on the enzymes and will reduces enzymes activities. A low pH will cause the hydrogen ion to alter the enzymes sites and reduce their activities while high pH will cause the hydroxides ion to alter the enzymes activity sites.
