Short notes on the five essential stages of Demographic cycle
Demography is the scientific study of human population. It focuses its attention on the following three observable human phenomenon:

This is a sample letter to file a FIR for theft of your cycle. This is to inform you that my cycle has been stolen from the cycle stand in the daily market last evening.
Most of our motives have a cyclical nature- they are aroused, they trigger behaviour, which leads to a goal and finally, after the goal is reached, they are shut off.
The eggs after fertilization stay in the uterus for some time which later rich the bile duct, then in the intestine of the host and finally pass out with the faces.
After a cone has been built by an eruption, the period of following quiet witnesses the development of consequent radial drainage and according to O.D. von Engeln this is the stage of youth in the erosional cycle that has started on the cone.
Infection occurs by 'Adsorption' of bacteriophage by the host cells and entry of nucleic acid inside the host cell. The adsorption of bacteriophage by host cell depends on their mutual affinity.
Bacteriophage (Greek = Backterion = small rod, phagein = to eat) Viruses which are bacteria eaters are called bacterial viruses or Bacteriophages. They are obligate parasites of bacteria. Usually they are very minute and cannot be seen with ordinary light microscope.
Water cycle is another important material cycle. Water is one of the important substances necessary for life. On average water constitutes 70% of the body weight of an organism.
Phosphorus, calcium and magnesium are components of the sedimentary cycle. Sulphur is to some extent intermediate, since two of its compounds hydrogen sulphide and sulphur dioxide formed under some circumstance, add a gaseous component to its normally sedimentary cycle.
Cycle concept in geomorphology has been quite useful and logical despite those who have tried to wriggle out of this reality without much success. Those who believe in geomorphic cycle do not and cannot believe that the evolution of landforms is in a cyclic order in the literal sense or that at the end of one cycle another cycle of the same magnitude starts.
