In order to caluclate the specific activity of the isolated
Anastaziya [24]

Answer:

Explanation:

This is evident that all enzymes are proteins but not all proteins are enzymes. The specific activity can be define as the number of enzyme units per milliliters that is divided by the available concentration of the proteins typically in mg/ml. Thus the value of the specific activity can be measured in  units/mg.

In others words this can be said that how much enzymes units can be found in the 1 mg of the total protein. So in the total concentration of the proteins the estimation of the enzyme units is possible. Thus protein concentration is necessary for calculating the number of the enzyme units.

If I subtract 20 from my number, then square the result, I get the same answer as if I square my number, then subtract 20 from t
Natasha_Volkova [10]

The value of the unknown number is 10.5.

Let the unknown number = x

When 20 is subtracted from the number and the result is squared which is equal to the square of the unknown number minus 20:

(x - 20)² = x² - 20

<em>expand the equation;</em>

x² -  40x  +  400 = x²  - 20

<em>collect similar terms together;</em>

x² - x² - 40x = -20 - 400

-40x = -420

x = \frac{420}{40}\\\\ x = 10.5

Thus, the value of the unknown number is 10.5.
