Describe three possible effects of genetic drift on populations and/or specific alleles.

vfiekz [6]

Answer:

Genetic drift can result in the loss of rare alleles, and can decrease the size of the gene pool. Genetic drift can also cause a new population to be genetically distinct from its original population, which has led to the hypothesis that genetic drift plays a role in the evolution of new species.

In regions of the cardiovascular system where there is steady laminar blood flow, the shear stress on cells lining the walls of

Lynna [10]

Answer:

$250$ N/m2

Explanation:

Shear stress on cells lining the walls of the blood vessels is equal to $20$ 20 dyne/cm2

In terms of Newton/square meter, shear stress is equal to

$20*\frac{dyne}{cm^2} (\frac{10^{-5}N}{1 dyne} )*(\frac{1 cm^2}{10^{-4}*m^2} )\\= 2.0$ N/m2

Shear modulus is equal to shear stress divided by shear strain

Thus, shear modulus is equal to

$= \frac{2.0}{0.008} \\= 250$ N/m2
