What do you understand by the term Gravitational Lensing?

Gravitational Lensing is a natural phenomenon that magnifies light around galaxies.  The phenomenon occurs when a huge amount of matter, such as a massive galaxy or cluster of galaxies, creates a gravitational field that distorts and magnifies the light from objects behind it, but in the same line of sight. This makes dim, faraway objects … Read more

What is robotics? write down its application in agriculture? (science)

Robotics is a branch of engineering that involves the conception, design, manufacture,                 and operation of robots. This field overlaps with electronics, computer science, artificial intelligence, nanotechnology and bioengineering. Application in agriculture: Robots can be used to farming on a large scale, with efficiency and in lesser time. Helps  in extensive farming. Robots make it … Read more

DMPQ-Briefly describe photonics. Also mention the need of photonics.

. Photonics is the science of light. It is the technology of generating, controlling, and detecting light waves and photons, which are particles of light. The characteristics of the waves and photons can be used to explore the universe, cure diseases, and even to solve crimes. Scientists have been studying light for hundreds of years. … Read more

DMPQ-. Give a brief description about Bio-piracy with examples.

As genetic research becomes more sophisticated, so does our ability to use plants and animals to develop new drugs or modify crops to meet food security needs. Often, in the search for new bio resources, researchers draw on local people’s traditional knowledge about the properties of a particular plant, animal or chemical compound. When researchers … Read more

DMPQ-What is hydroponics? Mention the important factors necessary for successful practice of hydroponics.

Hydroponics, or growing plants in a nutrient solution root medium, is a growing area of commercial food production and also is used for home food production by hobbyists. Learn about the state-of-the-art techniques for producing food in a controlled, soilless setting. Major factors to ensure the successful hydroponics practice are as follows: Ensuring water quality … Read more

DMPQ-. Describe the basic concept of Cloning. Also mention the potential drawbacks of applications of Cloning.

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- Point out the major components and applications of biometric system.

A biometric system is a technology which takes an individual’s physiological, behavioral, or both traits as input, analyzes it, and identifies the individual as a genuine or malicious user. Basic Components of a Biometric System Input Interface (Sensors) It is the sensing component of a biometrics system that converts human biological data into digital form. … Read more

DMPQ- Explain the potential disadvantages of Transgenic crops.

A concern about what affect genetically modified material could have on human health. For example, transgenic crops have been suggested to cause allergies in some people, although it is uncertain whether transgenic crops are the source of this reaction. Furthermore the antibiotic resistance genes placed in these crops has been suggested to cause resistance to … Read more
