If a trait has high heritability: Group of answer choices Hereditary differences account for none of the observed variations in that characteristic within that population. The environment cannot influence that trait. It is still possible for the environment to influence that trait. The trait is not influenced by heredity.

Option B, The environment cannot influence that trait.

Explanation:

Heritability is the measure of effectiveness of a gene to explain majority of genetic variations in a given set of population. This can also be measured mathematically in terms of number in a way that if heritability is close to 5 it means that gene is able to explain maximum genetic variations and if the heritability it close to 1 it means that gene is unable to explain the genetic variation and hence the variations are not genetic.  

Thus a trait having a high heritability means that it will be inherited and hence will produce genetic variations in offspring. Therefore, the impact of external factors such as environment on genetic variations of offspring will be the least or negligible.

Hence, option B is correct

you are certainly talking about this picture:

a: is the label of the white square, it is showing the  replication fork, formed by helicase (d) ==> so it is the site of dna separation and replication 

b: is a new dna brand that is following directly the replication fork, so it is continuous ==> built continuously from 5' to 3

c: dna polymerase cannot replicate dna on its own, it needs the of their proteins, and one of them plays the role of a clamp which fixes  the dna with the dna template and increases  the processivity of the enzyme. ==>   stops polymerase from falling off the  template.

d: is the enzyme responsible for forming the replication fork (helicase) ==> unwinds and separates dna into two strands

e: is the delayed strand, it is built  in the opposite sense of the helicase, so dna will be built in fragments ==> built  fragments from 5' to 3 joins

and finally f: is the enzyme that builds  the new dna strand (dna polymerase) ==>   adds nucleotides to make a new dna helix.
