The rate at which the concentration of a drug in the bloodstream decreases is proportional to the concentration at any time t. I
Westkost [7]

Answer:

C(t) = C_oe^{-kt}

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:

\dfrac{dC}{dt} decrease proportionally to Concentration C

i.e

\dfrac{dc}{dt} \alpha - C

\dfrac{dc}{dt} = -k C

\dfrac{dc}{c} = -k dt

\int \dfrac{dc}{c} = -k \int dt

㏑(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

\dfrac{C}{C_o} = e^{-kt}

C(t) = C_oe^{-kt}

∴

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

C(t) = C_oe^{-kt}

Blo 182 in assignments the artificial selection of which organisms was useful for darwin to come up the term natural selection?
miss Akunina [59]

When Darwin returned to England aboard the HMS Beagle after his voyage to the Galapagos Islands, he used artificial selection to help gather data to justify his theory of evolution. After studying the finches on the islands, Darwin moved to raising birds, notably pigeons, back home to test his theories.

<h3>What, according to Darwin, is artificial selection?</h3>

Artificial selection is the discovery of desirable qualities in plants and animals by humans, as well as the procedures taken to improve and maintain such traits in future generations.

They may adjust an organism's properties by choosing which creatures were permitted to reproduce. . Darwin referred to this form of alteration in organisms as artificial selection.
