Answer:
Denitrification = bacteria convert nitrates into nitrogen gas.
Denitrification occurs when nitrogen is removed from the soil and this happens when bacteria concert nitrites back to Nitrogen gas.
Nitrification = Bacteria convert ammonia to nitrites and nitrates.
Nitrification is the process by which bacteria concert ammonia made from ammonification into useful organic compounds like nitrites.
Nitrogen fixation = bacteria break down waste products and return nitrogen to the soil.
Nitrogen fixation is when bacteria return nitrogen to the soil by breaking down waste products that fall into the soil.
Ammonification = bacteria convert atmospheric nitrogen to ammonia.
During ammonification, bacteria converts nitrogen compounds to Ammonia or Ammonium.
Assimilation = Plants and animals take in and use nitrogen compounds.
Assimilation then occurs when plants take in these nitrogen compounds and use them. Animals will get these compounds by eating the plants.
We have that all of life is organized in 5 kingdoms. The animals and the plants are pretty straightforward; the first one contains most organisms that produce their own energy and the second one contains multicellular organisms that usually move. Fungi are a kingdom whose members are both multicellular and monocellular and they are eukaryotic. Protista are eukaryotic unicellular and Monera are prokaryotic unicellular. Most of the pathogens that we treat today are either fungi (athlete's foot) or are caused by bacteria which are contained in the kingdom of monera. A lot of protista can also be pathogens; a prime example is the disease of malaria whose cause is a protist. Viruses are also a big threat to health and are called pathogens but they do not constitute a kingdom (we do not classify them as alive). Hence, the three correct choices are Protista, Monera and Fungi.
Answer:
Amino acid sequences
Explanation:
The proteins perform the vast majority of functions in the cells. If a gene between a human and a mouse is evolutionarily related, it means that the function they do in the cell is quite similar in both species. This is the reason why the amino acid sequence would be the most similar.
In addition, there might be certain mutations in the DNA and therefore in the RNA between this 2 sequences that encode to the same amino acid sequence. More specifically speaking, there are more than one codon that encode to the same aminoacid. Thus, 2 different DNA/RNA sequence can give the same aminoacid sequence.
