Read MoreWhat are amphibious fishes? Can they live outside water?
The fishes that can survive without water for a good amount of time are known as amphibious fishes. Convergent evolution plays an important role in these species, as the next generation species receives analogous structures that have similar function but were not present in the last generation.Many fishes are amphibious, which means they can naturally survive out of the water. These fishes have developed limbs or use lateral undulation (that is, wave-like movement patterns that act to propel an animal forward) for terrestrial locomotion. They leave water bodies for many reasons like escaping predators, low oxygen environments etc.Ancient fish had ...

Read MoreExplain the working of a turbojet engine.
A turbojet engine is used in Aircraft. These are air-breathing engines which suck in air from the atmosphere for combustion. It has various components like inlet, compressor, combustion chamber, turbines, and nozzle. Air is drawn into the turbojet engine, compressed, mixed with fuel, and burned continuously.The exhaust product of this burning operates the turbine for the compressor, producing thrust which propels the aircraft. Turboprops are used in smaller and slow-paced air crafts as turbojets are not efficient at low speeds whereas turbofans have better specific fuel consumption than the turbojet. These engines are generally installed below the wings or near ...
Read MoreHow can India create more salaried jobs?
India is a developing country. Got bored of hearing this again and again, right? For it to be a well-developed country, India needs to focus more on developing its economic status.

Read MoreWhat is the difference between scramjet and ramjet engines?
Both scramjet and Ramjet are types of jet engines. A ramjet is an air breathing jet engine which is usually associated with supersonic transport. Ramjets can start at supersonic speeds only, so as a result they cannot be started at zero velocity and cannot produce thrust as there is a lack of airspeed.Hence assisted take off flights or rockets are needed to or accelerate it to a supersonic speed from which it starts producing thrust. This makes ramjet engine to be efficient only at supersonic speeds as it can accelerate to speeds of about Mach 6. Ramjet has revolutionized Rocket ...
