The recommended order of draw for a complete blood count, prothrombin time, and cholesterol is:

The use of the word "draw" here refers to the collection of blood samples for laboratory tests.

Step A - The first draw goes into the blood culture bottle or tube with a yellow cover.

Step B - This goes into the coagulation tube with a blue cover.

Step C - The next draw goes into the tube for non-additives. This usually has a red top

Step D - This features collection of blood into the tubes with additives. When dealing with additives, blood samples and additives it is important that the sample and additive is rigorously homogenized. This part can is broken down as follows:

b. lithosphere, asthenosphere, mesosphere   is the answer most likely

it provides an alternative energy pathway for the reaction to proceed.

a catalyst is a substance that speeds up the rate of a chemical reaction but is not consumed during the course of the reaction.

catalysts increase the rate of reaction without being used up. they do this by lowering the activation energy needed. with a catalyst, more collisions result in a reaction, so the rate of reaction increases. different reactions need different catalysts.

a catalyst works by providing an alternative reaction pathway to the reaction product. the rate of the reaction is increased as this alternative route has a lower activation energy than the reaction route not mediated by the catalyst.
