<span>Answer: T-cells are made to identify antigens, while inflammation fights anything in the affected area

The adaptive immune cells are made of B-cell and T-cell. The function of B-cells is to produce antibodies, while T-cells will detect antigens of the pathogen. If T-cells detect an antigen from a cell, it will assume that the cells are infected. It will send a signal to the infected cells which tell them to do apoptosis. Inflammation is not specific, which makes them not strong.
The concept would be crystallization. As magma cools inside or outside of the earth it crystallizes into an igneous rock. Intrusive (formed inside crust) igneous rocks are typically more course grained and contain many different noticeable minerals (for example, granite). Extrusive (formed outside) igneous rocks are typically more porous and are more fine grained then intrusive rocks (example, obsidian).
Answer: a naturally occurring depsipeptide used in the transport of potassium
I would say C.nervous system because that pretty much defines all of the answer choices.
