17. Which of the following examples of an ecological effect leading to an evolutionary effect is most correct? A) When seeds are
dusya [7]

Answer:

The correct option is C.

Explanation:

Evolution refers to the gradual development of living organisms from earlier forms to the forms that exist today. One of the principal factors that lead to evolution is the ability of an organism to adapt to adverse changes in its environment. Organisms that are able to survive adverse changes in their environments usually go on to produce offspring that possess their parents' ability to survive.  A good example of this is given in option C, where individuals with denser fur were able to survive from severe cold and then give birth to young ones that inherit their parents' ability to survive severe cold.

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}
