Use the Kelvin temperature scale.
Nitrogen fixation is the process that makes atmospheric nitrogen available to plants by mutualistic and free-living bacteria. The process is undertaken by the rhizobium bacteria that live in root roots of plants such as legumes. The mutualistic relationship is that the plant supplies the bacteria with a habitat in which to live, water, and nutrients, and the bacteria supply nitrogen for making plant proteins.
Answer:
(a).
![order \: of \: A = 2 \\ order \: of \:B = 0 \\ rate = k[A] {}^{2} [B]](https://tex.z-dn.net/?f=order%20%5C%3A%20of%20%5C%3A%20A%20%3D%202%20%5C%5C%20order%20%5C%3A%20of%20%5C%3AB%20%20%3D%200%20%5C%5C%20rate%20%3D%20k%5BA%5D%20%7B%7D%5E%7B2%7D%20%5BB%5D)
(b)

(c). The rate increases because kinetic energy of reactant molecules increases.
Answer:
decomposers
Explanation:
I'm not sure weather your supposed to create an actual experiment or write a paper. If an experiment, test certain acids to see which one can decompose plastics the fastest and determine which one can be spread through the oceans to melt down plastic. If a paper, discuss the idea of genetically modified fish. Some animals in the wild have the ability to eat pollution (wrappers, bottles, ect.), so mutating fish such as bottom feeders to be able to do the same would easily rid the water of pollution and make for one interesting of a paper! hope this sort of helped!
