Provide evidence that ancient antarctica was situated in a different location from its location today a. rock layers match up in antarctica and in the arctic b. it had to have been in a warm area and then moved there by plate tectonics over time due to the warm-climate plant fossils found there
c. alfred wegener said the continents moved from their original places over time

answer: i don't know

explanation:

you need to provide a picture, otherwise i can't tell you.

if you can provide one, i'd be more than happy to you with this!

i think its y= -4x-14

if you add everything up correctly you should get 69 i got this because 50 plus 19 is it

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.
