T cells and B cells differ in the form of the antigen they recognize, and this affects which antigens they can detect. B cells bind to antigen on invaders that are found in circulation outside the cells of the body, while T cells detect only invaders that have somehow entered the cells of the body.
ABS, DWV, Solid or Cell Core sewer pipe. The solid pipe is composed of ABS at 99% while the cell core is composed of a cellular foam between 2 layers of ABS which makes the cell core pipe lighter.
The flex pipe is a pipe that conects the exhaust manifold to you exhaust so that when the moter shifts it doesn't shake the whole exhaust syster. Yes it can be the reason that you car is so loud. OR, it is a cheap way to replace a faulty exhaust pipe. Hi, I own a 1990 Plymouth laser also. The flex pipe is on what they call the J pipe. It attaches your exaust manifold to your catalytic converter. There is also a brace for the J pipe that runs from the pipe right under the manifold and attaches to your engine block. It has been known to cause a hole in the pipe where it wraps around.
