Answer:
It means that the cell membrane allows certain substances to pass through and not others. As the cell membrane consists of a phospholipid bilayer with a hydrophobic core, only small uncharged hydrophobic molecules can pass through the cell membrane e.g. glucocorticoid and other larger charged particles require transporters or channel proteins to pass through the cell membrane, e.g. glucose.

Answer:
Jimmy's blood type: "O" Blood
Jimmy can receive blood from: O blood type only.
Explanation:
The anti-A antibodies are present in the plasma of "B" blood type. Similarly, the blood type "A" has anti-B antibodies in its plasma. Since Jimmy's blood is showing agglutination with both "A" and "B" blood type, he has "O" blood type.
The "O" blood type has both anti-A and anti-B antibodies in its plasma and exhibits agglutination with both A and B blood type. The "A" antigen of "A" blood type reacts with anti A antibodies of jimmy's blood while "B" antigen of "B" blood type would exhibit agglutination with "anti B antibodies" of Jimmy's blood. He can get blood from "O" blood type only as he has both anti-A and anti B antibodies in his blood plasma.
