Which cell(s) must use ATP energy to move the molecules out of the cell? (Hint: When using energy by the cell molecules will move from Low to High) im not sure if its, both of them or a or b

Cell A

Explanation:

The process in cells that requires energy to transport the molecules from low concentration to high concentration is called active transport. During active transport, molecules move against the concentration gradient, from low to high concentration.

In the given diagram, cell A uses ATP energy to move the molecules out of the cell because the molecule concentration is high outside the side and molecules are moving from inside to outside that is from low to high concentration.

Hence, the correct answer is "Cell A"

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.

the  frequency of a wave represents  the number of wavelengths that pass a specific point per second. the unit for  frequency  is hertz (hz).
