Based on his observations on monohybrid crosses Mendel proposed two general rules to consolidate his understanding of inheritance in monohybrid crosses. Today these rules are called the Principles or Laws of Inheritance: the First Law or Law of Dominance and the Second Law or Law of Segregation. Law of Dominance Characters are controlled by discrete … Read more DMPQ- Mendel law of inheritance.

Rocket engine needs enormous amount of thrust to escape Earth’s gravitational pull. However the chemicals used for engines are Hydrogen and Oxygen (Hydrogen used as a fuel, while Oxygen as a oxidiser) that produces a good thrust, found in Earth in the form of gas. Carrying hydrogen and oxygen in their gaseous form will require … Read more DMPQ- . Point out the differences between cryogenic engine and semi-cryogenic engine.

Neutrinos are the elementary particles found in the universe, which have no charge and have very little mass. They are electrically neutral and have weak interactive force. They are generally formed in the nuclear core of the sun. Radio active decay is also one of the source of neutrinos. They have the unique property of … Read more DMPQ: What are neutrinos? How they are formed and list down their applications.

Carbon dots are fluorescent nanoparticles that show similar physical and optical properties to the well-known semiconductor quantum dots. However, the building block of carbon dots is made primarily out of carbon, with some doped heteroatoms, creating a nanoparticle that is more biocompatible and less toxic compared with the quantum dots that commonly contain heavy metals. … Read more DMPQ- What is carbon date and How they are useful?

There are several ways of removing particulate matter; the most widelyused of which is the electrostatic precipitator, which can remove over 99 per cent particulate matter present in the exhaust from a thermal power plant. It has electrode wires that are maintained at several thousand volts, which produce a corona that releases electrons. These electrons … Read more DMPQ :What is electrostatic precipitator? Explain with the help of diagram.

Cradle to grave digital identity that … Read more DMPQ- What is the vision of Digital India Mission?

Insat (Indian National Satellite System) was a multipurpose satellite system for telecommunications, broadcasting, meteorology and search and rescue services. Commissioned in 1983, Insat was the largest domestic communication system in the Asia-Pacific Region, and was a joint venture of the Indian Department of Space (DOS), Department of Telecommunications, India Meteorological Department, All India Radio and … Read more DMPQ- Give the brief description of India’s INSAT (Indian national satellite system) Program.

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 DMPQ: What is MIRV? Discuss its significance.

DRDO has played a stellar role since its inception in 1958. Having established a sound ecosystem and supported by a large pool of committed manpower, we have today a proven competence to produce strategic and state-of-the-art tactical military hardware and related technologies, in diverse disciplines covering Aeronautics, Missiles, Naval Systems, Armament & Combat Engineering, Electronics, … Read more DMPQ: Discuss the role played by DRDO in Life science field.
