Cells may be self-sustaining units of life, but they do not exist in isolation from the rest of the organism. A vital component of their existence is their capacity to receive and digest information from their external environment, whether that information refers to the availability of nutrients, changes in temperature, or differences in light levels.

Hope it helps:)

Answer from: Quest

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.

Agenetically engineered corn plant is approved for agricultural use. the plant produces pollen that can make its own toxins. these toxins protect the corn plant against pests and no longer require the application of chemical pesticide. what is a likely impact on the farmer of growing such a variety of corn? a- the financial costs for the farmer would be lowered since less crops would be lost to pests. b-the financial costs for the farmer would be lowered since more crops would be lost to pests. c-the farmer may be held responsible for increasing chemical pollution. d-the farmer's expenses for pest control would increase due to an increase in bee population.
