Explanation:
Answer:
· Nitrogen fixation
· Nitrification
· Assimilation
· Ammonification
· Denitrification
Explanation:
Nitrogen fixation is the process where nitrogen is converting into ammonium.
Nitrification is the process of ammonium oxidation into nitrate.
Assimilation is the process where animals and plants receive NO3. Plants are using this nitrate for proteins and acids.
Ammonification is the process where the nitrate that is contained in plants and animals is recycled after their death.
Denitrification is e the last process in this cycle and during this process nitrate is converting to gases.
<span>Yeast has the most important percentage of adenine with 31.3%, comparing to human which has 30.9% and other species like Streptococcus, Herring, and E.coli.
Generally, the percentage of adenine and thymine are equal, because they are linked together in the DNA, and the guanine and cytosine percentage are equal too. So if we have the percentage of adenine in the DNA of a species, we can figure out the other percentages.</span>

Answer: D) By decreasing the activation energy of a reaction
A catalyst is a substance that speed up the rate of chemical reaction without affecting the product of the reaction. They only affect the rate of reaction not the yield of reaction.
Catalyst provide an alternative reaction pathway that has lower activation energy than that of uncatalysed reaction. It increases the frequency of collision and because of these greater collision which lowers the activation energy of the reaction.
