hyphae(thread-like structures) can grow and penetrate human skin

3 ways that white blood cells can defend against pathogens

8 of 17
1 pro and 1 con of vaccination
pro= helped control communicable diseases that were common. con= don't always work/give you immunity

human cells and tissues
10 of 17
what's meant by a drugs toxicity
how harmful it is
11 of 17
what is a monoclonal antibody?
they're produced from lots of clones of a single white blood cell. Identical antibodies
12 of 17
why might a fluorescent dye be added to monoclonal antibody?
they bind to the specific molecules and they will attach to them if present and therefore will be attached to the dye
13 of 17
why aren't monoclonal antibodies used as drugs as much as scientists hoped they would be?
they have lots of side effects
