Passive transport is dependent on the permeability of the cell membrane, which, in turn, is dependent on the organization and characteristics of the membrane lipids and proteins. The four main kinds of passive transport are diffusion, facilitated diffusion, filtration and osmosis.Simple diffusion is the unassisted passage of small, hydrophobic, nonpolar molecules.

The molecules on pathogens that enable the immune system to distinguish one kind of pathogen from another are called antigens. Antibodies destroy pathogens by binding to the antigens on the pathogen.

Small, Non-polar molecules. If the molecule is polar, it sticks to both sides of the membrane, and has to go through selective routes. The easiest to get through is the Non-polar (oxygen and carbon).

Most molecules can move in and out of a cell, but different molecules have different methods of getting in- Small Non-Polar molecules can diffuse across the lipid bilayer Medium sized molecules of any kind require a specific protein channel HUGE MOLECULES require a process called endo and exocytosis

Allergies should not be affected by your blood type. Your blood type is determined by antigens in your blood stream. Allergies are different. A simple allergy test performed by your doctor can tell you what you are allergic to, and what precautions you should take.
