Molecules tend to move from an area where they are more concentrated to an area where they are less concentrated. This process is called diffusion.

Explanation:

Diffusion is a frequent way of transporting substances through the cell membrane. In the diffusion process, the molecules of a region of high concentration tend to move to an area of low concentration until it is equal throughout a space, due to the kinetic energy of the molecules.

This movement of molecules depends on the thermal energy of a particle system and the difference in concentration between the two regions or areas, so that the net flow of particles from a region more concentrated to another less concentrated can be understood as simple diffusion or passive particle transport. In the case of cell membranes, simple diffusion depends on the concentration and the type of molecule to be transported.

This process is called diffusion

Explanation:

More facillitated diffusion, because it moves from high to low concentrated areas, see 7th grade science textbook.

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.
