Muska domestica : The Housefly SYSTEMITIC POSITION Phylum : Arthropoda Subphylum : Mandibulata Class : Insecta Subclass : Pterygota Division : Endopterygota Order : Diptera Family : Muscidae Genus : Musca Species : domestica HABIT AND HABITAT The common housefly, Musca domestica is of world- wide distribution, abundantly found around human habitation and filthy and dirty place to an active insect flying freely from one place to another and feeding upon human debris and other decaying organic matter. It is a dangerous house pest as it serves as a carrier of many disease-producing organisms on its body surface or hairs. The fly is diurnal as it shows much activity during daytime and in sunlight. It neither bites nor stings but its mere presence becomes intolerable to a conscious person, fearful of invisible enemies adhering to it. ...

T he Mosquitoes SYSTEMATIC POSITION Phylum : Arthropoda Class : Insecta Subclass : Pterygota Division : Endopterygota Order : Diptera Genus : Culex or Anopheles Mosquitoes are found in damp and marshy localities. They are abundant in tropics and subtropics. They are nocturnal in feeding habit. Females feed on blood ( sanguivorous )of man and large animals, while males suck juices of flowers and fruit. Because of their blood sucking adaptation, females are medically important as carriers of viral, bacterial and protozoan infection. Anopheles carries malaria, Culex carries dengue and elephantiasis and Aedes carries yellow fever. Adult mosquitoes fly well and can cover great distance. They are able to fly without rest for 2 or 3 hours and easily cover 20 to 30 kilometers in a night. Females become aggressive after copulation. They lay eggs in water where development of larvae and pupae takes place. Two common mosquito genera, ( Anopheles and...
E=mc 2 Energy – mass equation is given by Sir Albert Einstein. It states that energy can convert into mass and mass can convert in energy. In this equation: - E = energy m = mass, Unit of mass is kilogram (kg) c= speed of light (3x10^9 m/s) Every thing is right, than what’s the problem with it? The problem is what is the work of c 2 is this equation. If you ask to anyone about c 2 than their answer will it’s a constant. As a “ Science Lover” I will tell you about it. How can I tell you about the equation! Ah…… Let’s take an example of kinetic energy Formula of kinetic energy is: K=1/2 mv^2 In this equation m = mass v = velocity, unit of velocity is m/s. Let’s relate with E=mc 2 K= 1/2 mv^2 ...
