Asoccer player complains of locking and pain that is localized in the knee. on further interview, the nurse learns that the player has a history of knee trauma. on further assessment, the nurse suspects a torn meniscus. which test the nurse in coming to this conclusion?

Internal and external rotation of the knee can test for tears in the lateral meniscus and medial meniscus respectively. If the knee is injured, palpation of the knees during these rotations will produce a thud or a click. An MRI of the area would be the next step after the initial diagnosis.

Answer:

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

explanation:

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.

The rate that would change would be the  searching efficiency/attack rate. there are only two other rates in this model: the  growth rate of prey, and the  predator or consumer mortality rate.the  searching efficiency/attack rate is what indicates how effectively can a predator capture its prey whether in the searching process or actual capturing/attacking process.
