B - They have repeating steps
Metabolizing nitrogen in prokaryotes is very important to other organisms since these prokaryotes are able to convert ammonium in the soil to nitrate and, then, the denitrifying bacteria could use the nitrate produced instead of using oxygen in their metabolism in order to release nitrogen molecules. by the denitrification process, thus completing the nitrogen cycle. Without the nitrogen metabolism in prokaryotes, the nitrogen in the atmosphere could not be used or utilized to synthesize essential organic compounds that are needed by other organisms. It is only the prokaryotes that has the ability fixing nitrogen or can do the process of nitrogen fixation.
Answer:
there is no evidence of the big band or evolution, even Charles Darwin himself said that is was untrue
D is false

I believe the answer is: <span>Spores are released into the environment and grow into male and female gametophytes.
This Phase happens after </span>a haploid egg cell is fertilized by a haploid <span>sperm and then released to the environment. . This will result on Double sites of chromosomes that held by each parent (</span><span>grow into male and female gametophytes.)</span>
