The biological basis for assigning all human beings into a singe species is that there so many, even tons of living organisms living on earth. These organisms differ in their external and internal organs and so to differentiate them from them, they are being classified into kingdoms then classes then phylums then family.

What happens to the nitrogen in a rabbits body<br>when it dies<br><br>​
zepelin [54]

Answer:

When rabbit dies, the nitrogen in the rabbits body is released into the soil  by decomposition.

Explanation:  

When rabbit dies its body is decomposition takes place. Decomposition is process of breaking down of the dead remains of the plants, animals and insects into tiny pieces by free living bacteria, fungi and worms present in the environment .

During the decomposition process the nitrogen present in the dead rabbit body is released into the soil in the form of ammonia. The bacteria(nitrifying bacteria) present in the soil converts this ammonia into nitrates so that it can be again used by the plants. Now plants intakes this nitrates for photosynthesis process. This process of fixing nitrogen back into the atmosphere is called nitrogen cycle.

Large amounts of oxygen gas first appeared in earth's atmosphere about ______ years ago. 500,000 3.5 million 10 million 2.7 bill
Lostsunrise [7]

Answer:

2.7 billion

Explanation:

This period is referred to as the Great Oxygenation Event. This period saw the evolution of photosynthetic organisms (cyanobacteria) that utilized carbon dioxide (that dominated the atmosphere then) and sunlight to manufacture their energy molecules-glucose. Photosynthesis produces oxygen as a byproduct that is evolved into the atmosphere. As these photosynthetic organisms proliferated on earth, the atmosphere composition changed to become partly dominated by oxygen (which is an oxidaton agent) with less and less carbon dioxide.
