Answer:

Explanation:

Homologous chromosomes are similar but non-identical chromosomes received from each parent. They are non-identical in the sense that they may contain different alleles for the same gene. For example, in this case, D and d alleles on each homologue. These homologous chromosomes are usually involved in meiotic division, which occurs in a two-step division process; Meiosis I and II.

In meiosis I, homologous chromosomes separate/pulls apart, specifically during the anaphase stage. Alleles D and d borne on the HOMOLOGOUS pair of chromosomes are separated in the process with each of them going to either pole of the cell, according to Mendel's law of segregation.

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:

$C(t) = C_oe^{-kt}$

No beacuse the other layer may be to cold or hot for humans to survive in
