Application: In India radar imaging are used for crop estimation because our main crop growing season of kharif is in May-September when it rains and gets cloudy. We have used this data extensively for forestry, soil, land use, geology and during floods and cyclone. Due to an all-weather seeing feature, the satellite becomes special for … Read more DMPQ-What is RISAT- 2BR1? What are its application?

Anaerobic respiration occurs without oxygen and involves the consumption of another molecule (nitrate, sulfur, iron, carbon dioxide, etc.) instead of oxygen. Unlike in fermentation, anaerobic respiration involves the formation of an electrochemical gradient by an electron transport system that results in the production of a number of ATP molecules. Unlike in aerobic respiration, the final … Read more DMPQ- How do extremophiles like some bacteria and archaeans survive in environments without oxygen?

SCNT is a laboratory technique for creating an ovum with donor nucleus. In it, nucleus containing the organism’s DNA of somatic cell (a body cell other than sperm or egg cell) is removed and rest of cell discarded. The nucleus of somatic cell is then inserted into enucleated egg cell which reprograms somatic cell nucleus … Read more DMPQ-Write a short note on somatic cell nuclear transfer.

Cloud seeding is the process of spreading either dry ice, or more commonly, silver iodide aerosols, into the upper part of clouds to try to stimulate the precipitation process and form rain. There are three cloud seeding methods– Hygroscopic cloud seeding disperses salts through flares or explosives in the lower portions of clouds. The salts grow in size as … Read more DMPQ: What is cloud seeding? What are its possible application?

Thermoelectric power generators are the devices which used to convert temperature difference between two junctions into electrical energy. A working of thermoelectric generator is based on Seebeck effect.  According to which, a loop of two dissimilar metal develops an emf when the two junctions are kept at different temperature. That is why it is also referred as Seebeck … Read more DMPQ-Explain the concept of functioning of Thermoelectric Generator.
