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).

Because air quality circulates through the entire world. Getting ride of rainforest in the Southern Hemisphere will hurt the air quality which will eventually get to the rest of the world.
By conservation of momentum,
(900 kg) (15.0 m/s) i + (750 kg) (20.0 m/s) j = (900 kg + 750 kg) v
where v is the velocity vector of the combined cars. Solve for v :
(13,500 i + 15,000 j) kg•m/s = (1650 kg) v
v ≈ (8.18 i + 9.09 j) m/s
Then the direction of v relative to East is θ such that
tan(θ) ≈ 9.09/8.18 ⇒ θ ≈ 48.0°
so the wreckages would move at approximately 48.0° north of east.
