Braces are important because they a. protect you from impacts b. provide support for a weakened joint c. apply pressure to cuts and scrapes d. keep your joints cool and comfortable select the best answer from the choices provided. a b c d

b. provide support for a weakened joint

Braces are designed to provide stability to weakened joints by providing support to them. They help in joint alignments, prevents undue pressure on them and relieves from pain and ensures proper healing.

population. population is the number of people or animals in a particular place. an example of population is over eight million people living in new york city.

here is your answer hope i .

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.
