The study of morphology also reveals some organisms form links between two different groups. There is further evidence that evolution has taken place and it also shows the direction taken by the process of evolution. These organisms that show the features of two different groups are called the ..

The consistency of DNA copying during reproduction is important, which leads to the stability of population species. Changes in ecological system, which are beyond our control like varying temperature, varying water levels and natural calamities, can wipe out the population spe..

Summary - In the modern system of classification, living organisms are grouped under five kingdoms, as proposed by Whittaker (1966). The Kingdom Monera includes bacteria and blue green algae, both of which possess prokaryotic cells. Bacteria are unicellular prokaryotes that have..

Importance of Studying Transportation - Transportation whether in plants or animals is the key to the efficient assimilation of the nutrients that the organisms synthesise, get from their environment or digest. The study of these processes helps us in many ways. The study of transport mec..
