Answer:

Explanation:
From the given information:
At any given time (t), let c(t) represent the concentration of the drug present in bloodstream.
Deriving the equation:
decrease proportionally to Concentration C
i.e




㏑(C) = -kt + λ
where,
λ is the integration constant.
Integrating at t = 0, concentration of blood = Co g/mL
C(0) = Co
㏑(C₀) = 0 + λ
λ = ㏑(C₀)
From ㏑(C) = -kt + λ
㏑(C) = -kt + ㏑C₀
㏑(C) - ㏑C₀ = -kt


∴
The concentration of drug in blood at any time t is:

Fossil fuels and dissolved carbon compounds in the oceans
To transcribe the mRNA to make the DNA, we use genetic codes called codons. These are composed of three amino acids clumped together. It could be Adenine(A), Guanine(G), Uracil(U) and Cytosine (C). The difference is that first thread contains GUG, while the second one contains AGU. GUG is for Histidine while AGU is for Serine.
