Water is essential for life. The types of plants and animals distributed in water bodies greatly depends upon the nature of water, fresh water or sea water. The organisms have to face different problems of water scarcity or abun..

Organic cyanides has a triple bond between the C and N atoms i.e., one sigma and two pi bonds are present. Thus nitrogen here is sp hybridized. The C-C N bond angle is 180 o . Bond length of then the triple bond C N is shorter than the double bond C=N in imines and C - N single ..

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...

There are some structures in the body of organisms, which have no apparent use. Such structures are described as 'vestigial'. Vestigial organs indicate that they must have been present in a form in which they were highly functional in the ancestral..

The micro-organisms like cyanobacteria (blue-green algae) and photosynthetic bacteria can also fix nitrogen. Some cyanobacteria also act as symbionts and are present in association with lichens; liverwort - Anthoceros; fronds of water fern - Azolla and roots of a gymnosperm - Cy..
