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

The levels of carbon are expected to____ of our oceans
andreev551 [17]

Answer:

The levels of carbon are expected to_increase___ of our oceans

Explanation:

As humans activities increase the levels of carbon dioxide in the atmosphere so do the ocean levels of carbon increase. This is because of the fact that gases from the atmosphere dissolve in and out of the oceans at the interphase between the atmosphere and hydrosphere.

The more carbon dioxide in the atmosphere, the more the gas dissolves in the oceans. This is why more corals are bleaching around the world. The dissolved carbon dioxide is lowering the pH of the ocean waters because of the formation of more carbonic acid.
