Using the tally chart shown, find the difference between the number of living things and non-living things. => 3 or 2 or 4 or 1..

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 a wide di..

The respiratory system starts with the nose that encloses the nasal cavity . The nasal cavity opens outside through the openings called the nostrils . The nasal cavity is divided into two portions by a cartilagenous septum and is lined by fine hairs that filter the dust particles from the air...

Respiratory System in Human Beings The respiratory system starts with the nose that encloses the nasal cavity. The nasal cavity opens to the outside through the openings called the nostrils. The nasal cavity is divided into two portions by a cartilagenous septum and is lined by fine hairs that..

The study of morphology also reveals some organisms that form links between two different groups. This 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 ..

Ecosystem - Structure and Function - The characteristic structure of an ecosystem is obtained by the systematic physical organisation of the abiotic and biotic components of that particular ecosystem. The two main structural features of any ecosystem are its 'species c..

Did You Know? - The cells that make up our body are so small that you would fit over 200 of them on the full stop at the end of this sentence. The word cell is derived from the Latin word cellula which means a little room. It was the British botanist Robert Hooke who, in 1664, while examining a sli..

Organisation refers to a kind of structure or system or situation where the smaller components become arranged into larger ones in a hierarchical order of complexity, to co-ordinate with one another in performing common functions or achieving common goal..

Need for Classification - More than a million species of living organisms have been discovered and described so far and a large number of them are yet to be discovered. Scientists involved in this task, called taxonomists, estimate that there may be around 30 million species of livin..
