List the reasons why food chains to not send to exceed 4 links
Hitman42 [59]
As the number of organisms increase so does their tropic levels. As one organism eats the other energy is being transferred to that organism. The larger the food chain the lesser the organism' s would be because they would lose energy while trying to hunt and catch their prey and other activities. The food chain usually ends at the tertiary consumer or the fourth link because if it goes on like that there would be less energy hence these organisms would most likely starve and gradually die.

In humans, red blood cells have a number of proteins embedded in the cell membrane. One type of protein, the Rh factor, is contr
Reptile [31]

Answer:

The frequency of the Rh allele = 0.90

Explanation:

Given -

Rh is the dominant to Rh–

Therefore alleles for Rh will be represented by "p" and allele for Rh- will be represented by "q"

So  , the frequency of the Rh– phenotype is 0.01.

Which means q^{2} = 0.01

Hence, frequency for allele of Rh–

=\sqrt{q^2} \\= \sqrt{0.01} \\= 0.1

As per Hardy Weinberg's first equation-

p+q=1

Substituting the value of "q" in above equation, we get -

p+0.10=1\\p=1-0.1\\p=0.90

So the frequency of the Rh allele = 0.90
