Some verieties of food crops have Been genetically modified in an effort to improve upon a certain trait such as pest resistance or longer Shelf life. However, there are also concerns with genetically modified crops. Which of the following is most likely a concern about genetically modified crops? there may be an increase in global food prices .

there may be an increase in pest populations that adapt to the modified traits in crops.

there may be a decrease in a range of Environmental conditions in which a crop can survive.

there may be a decrease in the amount of time that fruits and vegetables stay fresh in the supermarket.​

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.

affects the water bodies: excessive use of fertilizers causes eutrophication. the fertilizers which are used on plants affect the quality of land on which it is used, further causing erosion of soil. the fertilizers used on plants contain harmful chemical fumes which affect the environment.

answer: substrate concentration. enzymes work best when there is a high enough substrate concentration for the reaction they catalyse.

i dont know it at allnow im just getting points at this pint
