Answer:
an inducer
Explanation:
An Enzyme is a protein molecule found in cells which work as biological catalysts.
They speed up chemical reactions in the body, but do not get used up in the process, and can be used over and over again.
In chemistry inducers are molecules that regulates gene expression, and can bind to protein repressors or activators.
Lactose here acts as an inducer because it inactivates the repressor of an operon.
The pH of the solution of the given acid is 3.099
Let HX be the weak acid:
HX ⇌ 
+ 
For which:
= [ ][ ] / [HX]
If lies in the range 
we can assume that the equilibrium concentrations used in the expression are a good enough approximation to the initial concentrations.
Rearranging and taking negative logs of both sides gives:
pH = ![\frac{1}{2} [pK_{a} - loga]](https://tex.z-dn.net/?f=%5Cfrac%7B1%7D%7B2%7D%20%5BpK_%7Ba%7D%20-%20loga%5D)
a is the concentration of the acid.
= -log (2×
) = 5.69
pH = ![\frac{1}{2} [5.69- (-0.508)]](https://tex.z-dn.net/?f=%5Cfrac%7B1%7D%7B2%7D%20%5B5.69-%20%28-0.508%29%5D)
pH = 3.099
