Two parents of known well defined characters belonging to two different species within a genus are crossed to achieve heterosis. Some important hybrids (both inter specific and intra specific) are listed ..

The plant hydrangea can have pink "flowers" or blue "flowers" (they're actually modified leaves). But we do not classify the two forms as different species. In fact, one could allow a blue-"flowered" plant to become a pink-"flowered" plant just by changing the pH of the soil and the amoun..

A stable and self sufficient community has certain specific characteristics. a) Habitat Biotic community occupies particular area with specific physical environment, which acts as a limiting factor, regulating the population size of various species within the community. b) Self sufficienc..

Question: Why are some forests known as biodiversity hot spots? Answer: Forests where a large number of flora and fauna species are found are termed as 'biodiversity hot spots'. The range of different life forms like bacteria, fungi, ferns, flowering plants, nematodes..

>t h century necessitated a thorough modification in the system of classification. A more systematic and scientific system called natural system of classification emerged.

Human evolution concerns itself with the emergence of humans as a distinct species. Undoubtedly, there are special features possessed by 'Homo sapiens' considered to be at the top of the evolutionary ladder but science has become fully committed to finding purely biological explanations..

The biotic component of our environment on land, i.e. plants and animals (leaving aside the oceans and other water bodies) are overwhelmingly found in forests. Forests form a buffer for the earth to protect life forms; in fact that's where all our biodiversity and including cultivated crops and ho..

Cyanobacteria reproduce mostly by vegetative and asexual methods. Vegetative reproduction occurs by fission or fragmentation or by the formation of hormogonia. Unicellular forms exhibit fission while filamentous multicellular forms exhibit fragmentation. Asexual reproduction occurs by the formation..
