Ms. Hakim’s class travels 1 km north on the road and finds a second roadcut. It has another layer of rock between layers Q and P. This layer (N) also has the igneous intrusion. What conclusion can you now draw about the rocks in the diagram? a) Blasting damaged layers at the original roadcut so layer N is not visible there.
b) Folding must have occurred at the original roadcut
c) There is an unconformity at the second roadcut
d) There is an unconformity at the original roadcut

i would have to say autosomal

it is either c or d and i know for sure it is not a or b

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.
