You have discovered a previously unknown organism. it is multicellular, with a filamentous form, and absorbs food from its environment. upon microscopic examination, you see that the cells have nuclei.
how would you classify this organism?
a. domain bacteria
b. kingdom animalia
c. kingdom protista
d. kingdom fungi

d. kingdom Fungi

Explanation:

The kingdom fungi includes the eukaryotic unicellular to multicellular organisms. These includes yeasts, moulds and mushrooms. These have cell walls, and nuclei. These are heterotrophs which means they are dependent upon other organisms for the food and nourishment requirements. These have filamentous structures called as hyphae which helps them to absorb the food from the dead and decaying matter present in the soil.

multiply it by 5 in order for you to understand i cant give an exact answer.

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.
