One of the major functions of erythrocytes (also known as red blood cells) is to carry blood gases such as oxygen and carbon dioxide around the body. Red blood cells contain the pigment haemoglobin which binds to oxygen and carries it around the body, releasing it and allowing the process of aerobic respiration.

In which animals are the blood and the interstitial fluid considered to be the same body fluid?
Katena32 [7]

Answer:

In insects such as cockroach, grasshopper

Explanation:

Insects such as grasshopper has open circulatory, in them the body fluid is the hemolymph. The hemolymph does contain any respiratory pigment. It bathes the organs directly as it is pumped between open spaces in the body.

Thus, in insects, the blood and the interstitial fluid considered to be the same body fluid?

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
