Heart - Shape and Position
It is a thick muscular, reddish brown, conical organ present in the mediastinal space of thoracic cavity between 2 pleura enclosing the lungs. Its broader side is called base and it is forward and upward while the pointed side called apex is backward and downward. It is 9 cm bro..
Regeneration
Regeneration of new plants from the vegetative parts of the parent plant is called vegetative propagation or vegetative reproduction. Vegetative propagation is done with the help of vegetative parts such as roots, stem or leaves. These parts may also be variously modified for vegetative propagatio..

Types of Food Chains
There are mainly two types of food chains operating in nature. a) Grazing food chain b) Detritus food chain. Grazing food chain is generally seen in ecosystems such as grassland, pond or lake where a substantial part of the net primary production is grazed on by herbivores (cattle and rodents). Usu..
iv) Basic character
Nitriles are very weak bases. Although protonated nitrile (conjugate acid) is stabilized by resonance, its resonance structure is a vinyl cation, which is not very stable. Despite their feeble basic character, their protonation is important in their acid catalyzed reactions. Due to this ..
