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.
This liquid substance most probably be a member of the group of lipids. Liquids which do not dissolve in water are called hydrophobic substances. Nonpolar substances exhibit this effect. Lipids are a class of large molecules or macromolecules which are hydrophobic. Lipids include cholesterol, fat, and phospholipids.
The correct answer is - False.
To trace the correlation between the rock layers by using fossils can be a big mistake, though occasionally it may provide the proper information, still it will be relying on luck.
The case is actually the other way around, the fossils can be correlated by using the rock layers, because each layer of rocks represents some time in the geologic past.
The fossils, on the other hand, are much more easy to be moved through the layers over time, because there can be disturbances, adjustments in the crust, or the rocks can change their composition under the influence of multiple factors. All of that can contribute to the fossils ending up at places where they aren't expected to be, so using them to correlate the rock layers will not be a very useful method.
