Distinguish between naturally and artificially acquired active immunity and give an example of each.

Naturally acquired active immunity:  It happens when someone is exposed to a live disease and gets the disease. The person then becomes immune as a result of the first immune response.

It's sort of like a fall and learn to get up for the body.

Artificially acquired active immunity:  It can be isert into the body by a vaccine so you won't get sick. That's why if you get a flu shot, you won't get the flu, if you get a chicken pox vaccine, you won't get the chicken pox.

It's like you're body has a personal guide telling it where and where not to step in order to not fall.

the cladogram shown here shows similarities and differences among several classes of vertebrates. anatomically, the four have limb structure as their common ancestor. we might separate the mammals from the other three classes because they a) divergent; do not lay eggs b) identical; are warm-blooded c) varied; a four chambered heart d) homologous; have mammary glands

igneous rocks are formed by solidification of cooled magma (molten rock), with or without crystallization, either below the surface as intrusive (plutonic) rocks or on the surface as extrusive (volcanic) rocks.  

the composition depends on the source magma. there are almost a thousand types of composition found till now.  

hope this
