Bacteria
Explanation:
Nitrification fixation takes place by nitrogen-fixing bacteria like Azotobacter, Klebsiella, Bacillus etc which convert atmospheric nitrogen gas into fixed-nitrogen compounds like nitrates or ammonium ions for the plants to readily absorb.
The nitrogen fixing bacteria can be free-living like cyanobacteria or live with symbiotic relationship with plants and fungi.
The chemical conversion of di-nitrogen to ammonia takes place with the help of enzymes like nitrogenase in combination with leghahemoglobin, a protein through a reduction reaction.
Some molecular studies point to amphibians descending from the lung fish, the Diponi.
Under the class Amphibia, amphibians are tetra-pod, cold blooded vertebrates without having scales. Protein is produced by the special skin of Amphibians.
Lung fish belong to the subclass of Diponi, these are living air breathing species.
Answer:
C
Explanation:
Mitosis is a growth division unlike meiosis which an organism undergoes to produce gametes or sex cells during sexual reproduction.
Mitosis is a kind of cell division that results in two daughter cells, identical in genetic composition. An organism can undergo mitosis in asexual reproduction. For each mitotic division, two daughter cells emerge (duplication division), which will propagate the number of the species.
In a case of heavy predation, the prey organism will depend on diverse number to keep its species from getting extinct. Hence, undergoing mitosis to duplicate itself asexually will be most beneficial in this scenario as a large number will increase the chance that some of them will not be a victim of predation.
