Antigens are cellular parts that are able to bind to antibodies. Antigens are usually made out of proteins or polysaccharides, so they include parts like the coats, capsules, or cell walls of pathogens (disease-causing bacteria, viruses, and other microorganisms). Antibodies are proteins that are produced by the immune system to prevent the growth and spread of pathogens. Antibodies bind to antigens, like keys fitting into specific locks.

How do temperature and salinity affect deepwater currents? they create changes in wind direction, moving denser water in the same direction as the wind and causing the deepwater circulation patterns found in the ocean. as temperatures and salinity levels of water increase, the water rises to the surface where it creates currents as it moves to colder regions. they create density differences that cause dense deepwater currents to flow toward the equator where they displace less dense, warmer water above them. they equalize the forces on undersea currents caused by the coriolis effect as they replace more dense water with less dense water.
