Answer:

They release chemical messengers to communicate with cells they may or may not be in direct contact with.

Explanation:

Unicellular organisms such as bacteria or yeast, 'talk' to each other through the release of chemicals. In bacteria, this is known as quorum sensing which allows them to determine the surrounding bacterial population density. In yeast, one of the more popular pathways is known as the mating factor pathway, which allow the organisms to find mates. Whereas, in multicellular organisms (such as humans), this chemical release allows for cell-cell co-ordination which keeps the system functioning correctly.

2. Antigens can trigger an immune response. Explain if this is a specific or a nonspecific defense.
masya89 [10]

This is a specific response because in order to fight antigens, white blood cells, the most important cells of the immune system, must produce large, Y-shaped proteins known as antibodies to fight these invaders. This is a type of specific defense (as I have identified antibodies as specific defenses is the chart above).
