Can someone help please

the mutation they are talking about deals with genes/dna

Explanation:

they show one person (j) who does not have the mutation and therefore does not have the syndrome h

then they show person (k) who has a mutation and therefore had syndrome h

look carefully at the letters on the lines. they represent the DNA in people and correlate to each other

(I hope this helped a little bit and I may he completely wrong but I think I'm mostly right)

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.
