In order to form a zygote, male gametes in pollen grains have to fuse with egg in the ovule. This is achieved by the process called pollination. Pollination is the process of transferring pollen grains from the anther – male part of a flower, to the stigma – female part of a flower. Depending on … Read more DMPQ- Define pollination and its types.

Navigation satellite is a system which provides system of artificial satellite that helps in providing autonomous geospatial positioning. It helps to provide positioning information regarding local time to high precision. Global positioning system launched(GPS) by NASA is an example of it. India Launched Indian regional navigation satellite system called IRNSS. It is a constellation of … Read more What is navigation satellite? India launched IRNSS recently, what is IRNSS? What are its application?

Cloning is the process of generating a genetically identical copy of a cell or an organism. Cloning happens often in nature—for example, when a cell replicates itself asexually without any genetic alteration or recombination. Prokaryotic organisms (organisms lacking a cell nucleus) such as bacteria create genetically identical duplicates of themselves using binary fission or budding. … Read more DMPQ-. Describe the basic concept of Cloning. Also mention the potential drawbacks of applications of Cloning.

FSOC technology uses beams of light to deliver high speed, high capacity connectivity over a long distance.  The energy beam is sent through clean air or space from the source to the destination, rather than guided through an optical fibre. As long as there is a clear line of sight between the source and the … Read more DMPQ: What is free space optical communication? Write down its advantages ( science)

Q.  Comets Ans:   Comets originate in outer solar system and are formed of cosmic snowballs of frozen gases, rock and dust that orbit the sun. When a comet’s orbit bring it close to the sun ,it heat up and spewn dust and gases into a giant glowing head larger than most planets.   Q.  Dark … Read more DMPQ: Define- Comets, Dark matter, Dark energy and Fundamental particle (Science)

Application of radioactivity: • Health: 1. Found extensive use in diagnosis and therapy eg. Phosphorous-32 is used to identify the cancerous cell. As cancer cell absorb more phosphorous, Iodine 131 is employ to determine cardiac output, plasma volume and fat metabolism and particularly to measure the activity of thyroid gland. 2. To treat cancer cells: … Read more DMPQ- List out the main Application of radioactivity.

IRS-1A, the first of the series of indigenous state-of-art operating remote sensing satellites, was successfully launched into a polar sun-synchronous orbit on March 17, 1988 from the Soviet Cosmodrome at Baikonur. The successful launch of IRS-1A was one of the proudest moments for the entire country, which depicted the maturity of satellite to address the … Read more DMPQ- “India’s remote sensing satellite system has important role in it’s development.” Elucidate.
