Digestion is the process of break down of complex food substance into simple molecules.  Digestion is carried out by our digestive system by mechanical and biochemical method. The digestive system consists of alimentary canal and the associate glands. The process of digestion is accomplished by mechanical and chemical processes. The buccal cavity performs two major … Read more

The most vital component of missile technology in recent years is the deployment of Multiple Independently targetable Re-entry Vehicle (MIRVs). The fundamental characteristic of deploying MIRVs is its ability to deliver several warheads along separate trajectories, which confers it flexibility of multiple targeting. The independent targeting capability enhances missile’s ability by exhausting the missile defence, … Read more

What is catalytic converter? What is its significance. Ans:       Catalytic converters, having expensive metals namely platinum palladium and rhodium as the catalysts, are fitted into automobiles for reducing emission of poisonous gases. As the exhaust passes through the catalytic converter, unburnt hydrocarbons are converted into carbon dioxide and water, and carbon monoxide and nitric oxide … Read more

Biopiracy is the practice of commercially exploiting naturally occurring genetic material or biochemical. Most of the indigenous people possess a traditional knowledge that mainly comprises of genetic diversity and biological feature of the natural environment from generation to generation. Some of the traditional knowledge that is relevant to global survival includes the following components. Medicinal … Read more

Biomagnification:         Biomagnification refers to increase in concentration of the toxicant at successive trophic levels. This happens because a toxic substance accumulated by an organism cannot be metabolised or excreted, and is thus passed on to the next higher trophic level. This phenomenon is well known for mercury and DDT. Bioremediation:  Bioremediation is a biotechnical process, … Read more

The progress of science in the 20th and 21st centuries exploded, creating technologies that reshaped society and extended lives. The pace of change was so great that it took society years to start asking questions about the ethics or morality of new developments. Now, humanity is at a major crossroads, where further investment in biotechnologies could change the way humans live … Read more

  Ballistic Cruise Launched directly into the high layers of the earth’s atmosphere A cruise is a guided missile that can destroy a target over long distance with high accuracy. Follows parabolic path Does not follow parabolic path It depends on gravity hence called ballistic. Does not depend upon gravity Classified by coverage Classified by … Read more

Air breathing propulsion system: In order to provide thrust by the launch vehicles propellants are used. 70% of the constituent of propellant is oxidiser.  So air breathing propulsion system utilise the atmospheric oxygen as an oxidiser to burn the fuel. Ramjet, Scramjet and Dual Mode Ramjet (DMRJ) are the three concepts of air-breathing engines which … Read more
