communication mechanisms. I have once been defined as “the process by which energy from a chemical reaction is transformed into light energy”. Marine bioluminescence is produced by an incredible range of organisms‚ from bacteria and single-celled protists to fish and squid. Bioluminescence is a form of luminescence‚ or "cold light" emissio. Ninety percent of deep-sea marine life is estimated to produce bioluminescence in some way. Bioluminescence‚ the emission of ecologically functional light by

the West Nile virus from bites of a mosquito. The mosquito associated with the West Nile virus is primarily the Culex pipiens mosquito. This mosquito is in the Animalia kingdom. So‚ you can infer that this mosquito does not contain prokaryotes or protists. Also‚ you can infer that the mosquito is multicellular‚ a heterotroph‚ and lack a rigid cell wall. The Culex pipiens mosquito reproduces sexually‚ and it is diploid (“West Nile Virus: Overview and

Science is an organized body of knowledge supported by observation and experimentation‚ derived from the natural phenomena of the entire material universe. Biology had flourished a great deal in ancient India. Various systems of classifying animals and plants were developed‚ for example Jeevaj (Viviparous) animals that give birth to young one‚ Andaj (Oviparous) animals that lay eggs‚ etc. Cultivation of rice was first introduced in India. It is estimated that more than 1000 varieties of rice had
