Blake's mistake is (d) He divided the exponents in the parentheses instead of subtracting.
<h3>How to determine the mistake</h3>
The expression is given as:
The actual solution is as follows:
Add the exponents
Multiply 15 by 5
Blake's simplified expression showed that:
He divided 12 by -3 and then multiplied the result by 5
Hence, Blake's mistake is (d) He divided the exponents in the parentheses instead of subtracting.

Answer:
In homogeneous mixture the constituent of the mixture are uniform and there is no presence of physical barrier between them.
A total of 3.75 x 10⁷ transcription factors are phosphorylated in response to the first messenger. The number of transcription factors phosphorylated if one copy of the d enzyme is inactivated is 3.7499 x 10⁷.
<h3>What is phosphorylation?</h3>
Phosphorylation is a posttranslational modification that suffers proteins during the activation of a singling pathway.
Phosphorylation is capable of activating and/or deactivating specific signaling pathways.
In this case, phosphorylation activates a molecular cascade involving the progressive phosphorylation of different substrates.
In this case, 3.75 x 10⁷ transcription factors are phosphorylated in response to the first messenger (100 x 100 x 75 x 50 = 3.75 x 10⁷), whereas the number of transcription factors phosphorylated if one copy of d enzyme is inactivated is 3.7499 x 10⁷ (3.75 x 10⁷ - 50).
