Isotopes are atoms of the same element with the same number of protons and different number of neutrons.

<h3>What are isotopes?</h3>

Isotopes are any of two or more forms of an element where the atoms have the same number of protons, but a different number of neutrons within their nuclei.

As a result of this, atoms of isotopes will have the same atomic number but a different mass number.

Examples of isotopes are

  • Carbon-12 and Carbon-14
  • Nitrogen-14 and Nitrogen-15

Therefore, isotopes are atoms of the same element with the same number of protons and different number of neutrons.

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}

What can you learn about a sample from an sds-page analysis?
puteri [66]

Option <u>(c.) the purity of the protein</u>, will be the right one.

Sodium Dodecyl Sulphate provides a negative charge to each protein as a function of their molecular size. It is an anionic detergent, as well as it is there to determine the relative abundance of major proteins.

After denaturing, proteins get unfolded and gets coated with SDS detergent molecules. The SDS-PAGE technique is used for the separation of protein based on their molecular size/weight/mass.

It is so because as it identifies the proteins by its molecular weight. Therefore, SDS is used in denaturing polyacrylamide gel electrophoresis for the determination of protein molecular weight, the SDS-PAGE is a technique.
