The idea that the universe began from a single point and
expanded to its current size explains a large number of
observations, including those in the table below.
In addition, many predictions based on the idea have led to
additional observations that support it. This idea of the
origin of the universe is best classified as a
Observations Explained
The universe consists mostly of low-mass elements.
Cosmic microwave background is nearly the same in all directions.
Light from other galaxies shows that these galaxies are moving away

not sure if this is what you'r looking for eubacteria and archaebacteria

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.

i think that it is c, d, and e, hope this
