In biology species can become isolated from other species through a number of processes. These isolation processes keep the two species from interbreeding and producing hybrid offspring. There are five separate isolation processes that prevent two species capable of producing offspring from being able to do so. Ecological Isolation Ecological‚ or habitat‚ isolation is when two species that could interbreed do not because the species live in different areas. For example‚ in the wild of India both

Hybridity in Ezekiel Mphahlele ’s Down Second Avenue The criticism that Mphahlele ’s awareness of his being a "hybrid ’ person imparts an inability to his being able to "write his story himself " is a criticism contrived out of literal derivations of the Greek components of the word "autobiography".

two centuries before that Dennis Papin[6]apparently came up with the idea of using compressed air (Royal Society London‚ 1687). In 1872 the Mekarski[6] air engine was used for street transit‚ consisting of a single stage engine. Numerous locomotives were manufactured and a number of regular lines were opened up (the first in Nantes in 1879). In 1892‚ Robert Hardie[6] introduced a new method of heating that at the same time served to increase the range of the engine which in turn helped

States‚ car companies have joined forces to develop newer cleaner technologies. The research on alternate fuel sources for cars began long ago‚ but it was not until 1999 that the first hybrid electric powered vehicle was sold. This car was manufactured by automaker Honda‚ and was called the Insight. An electric hybrid vehicle employs the operation of a small engine to assist a typically battery powered electric system. The electric motor propels the front wheels at low speeds‚ and then at higher speeds

Genetic Diversity In Agriculture Genetic variation is the raw material for the plant breeder‚ who must often select from primitive and wild plants‚ including wild species‚ in search of new genes. The appearance of new diseases‚ new pests‚ or new virulent forms of disease causing organisms makes it imperative that the plant be preserved‚ because it offers a potential for the presence of disease resistant genes not present in cultivated varieties. Also‚ there are demands for new characters-- for
