Answer:

(1) normally harmless cat antigens stimulated

the immune system

Explanation:

It isn't the fault of the respiratory system that the antigens produces an immune response to cat antigens but the specific genotype of the child. The genotype has developed his immune system too much sensitive mostly due to an anomaly or mutation. Now, normally harmless antigen will produce a immune response because it has enough potential of activation for induction of an immune response.

Which of these is correct regarding the permeability of a specific capillary type?
Vsevolod [243]
Red platelets are too vast to leave any capillaries. As capillaries are just a single cell thick and have thin porous dividers this implies substances can diffuse out of them effortlessly. Helpful substances, for example, oxygen and sustenance diffuse out of the blood in the vessels into the tissue liquid where it is then taken to the cells.

A farmer plants Bt cotton that is genetically modified to produce its own insecticide. Of the cotton bollworms feeding on these
-Dominant- [34]

Answer:

the frequency of the resistant allele after one generation is 0.989

Explanation:

Given that :

A farmer plants Bt cotton that is genetically modified to produce its own insecticide.

Of the cotton bollworms feeding on these Bt plants, only 5% survive

i.e the survival rate s  = 5% =0.05

unless they have at least one copy of the dominant resistance allele R that confers resistance to the Bt insecticide

Frequency of R allele = 0.01

In order to determine what will the frequency of the resistance allele be after one generation of cotton bollworms fed on Bt cotton; we need to first determine the frequency of the recessive allele r.

According to Hardy-Weinberg Equilibrium ;

p+q = 1

Let p = R and q = r

R + r = 1

0.01 + r = 1

r = 1 - 0.01

r = 0.99

Now; the  frequency of the resistance allele after one generation can be calculated as :

q' = \dfrac{q(1-sq)}{1-(sq^2)}

where ;

q' = R

q = r

q' = \dfrac{0.99(1-(0.05 \times 0.99))}{1-(0.05 \times 0.99^2)}

q' = \dfrac{0.99(0.9505)}{1-(0.049005)}

q' = \dfrac{0.940995}{0.950995}

q' = 0.989

Thus; the frequency of the resistant allele after one generation is 0.989
