He has a red rash covering his trunk and his blood pressure is 90/50 mm Hg. The EMT should: Select one: a. remove the stingers from his leg by scraping them with a stiff object. b. administer oxygen and epinephrine and prepare for rapid transport. c. apply warmth to the sting area and cover it with a dry sterile dressing. d. begin transport and immerse his leg in hot water to help reduce pain.

a. to encourage apoptosis

the answer is c a tornado

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.
