The lymphatic system has three primary functions: Fluid balance The lymphatic system helps maintain fluid balance. It returns excess fluid and proteins from the tissues that cannot be returned through the blood vessels.  The fluid is found in tissue spaces and cavities, in the tiny spaces surrounding cells, known as the interstitial spaces. These are … Read more DMPQ- What are the Functions of lymph system?

Renovascular hypertension Renovascular hypertension is high blood pressure due to narrowing of the arteries that carry blood to the kidneys. This condition is also called renal artery stenosis. renal artery stenosis is a narrowing or blockage of the arteries that supply blood to the kidneys.  The most common cause of renal artery stenosis is a … Read more DMPQ- Explain the Diseases related to kidney.

To describe the phenomena related to magnets, lines are used to depict the force existing in the area surrounding the magnet. These lines are called the magnetic lines of force. These lines do not exist actually, but are imaginary lines that are used to illustrate and describe the pattern of the magnetic field. As shown … Read more DMPQ- Explain the Magnetic lines of force and their properties.

Genetically modified crops are plants used in agriculture, the DNA of which has beenmodified using genetic engineering techniques. The aim is to introduce a new trait to the plant which does not occur naturally in thespecies. In food crops include resistance to certain pests, diseases, or environmentalconditions, and improving the nutrient profile of the crop. … Read more DMPQ:Write short note on Genetic modified crops.

Hydrogen bombs are thermonuclearweapons which employs fusion of isotopes ofhydrogen. The result is greatly increased explosivepower when compared to single-stage fissionweapons.The energy released in a Hydrogen bombis several magnitudes higher than anAtom bomb. A fusion bomb is more sophisticated anddifficult to make, since it requires a muchhigher temperature — in the order ofmillions of degrees … Read more DMPQ:What is the working principle of Hydrogen Bomb?

The Mission envisages empowering our national academic and R&D institutions spread over the country by installing a vast supercomputing grid comprising of more than 70 high-performance computing facilities. These supercomputers will also be networked on the National Supercomputing grid over the National Knowledge Network (NKN). The Mission would be implemented and steered jointly by the … Read more DMPQ- Write Short Note on National Supercomputing Mission. (SCIENCE)

Local Area Network (LAN) It is also called LAN and designed for small physical areas such as an office, group of buildings or a factory. LANs are used widely as it is easy to design and to troubleshoot. Personal computers and workstations are connected to each other through LANs. We can use different types of … Read more DMPQ- What do you mean by Local Area Network (LAN)? Explain its applications.

Linear motion, also called uniform motion or rectilinear motion, motion in one spatial dimension.  According to Newton’s first law (also known as the principle of inertia), a body with no net force acting on it will either remain at rest or continue to move with uniform speed in a straight line, according to its initial … Read more DMPQ- What do you mean by Linear motion

Applications of tissue culture Rapid Clonal Propagation A clone is a group of individuals or cells derived from a single parent individual or cell through asexual reproduction. All the cells in callus or suspension culture are derived from a single explants by mitotic division. Therefore, all plantlets regenerated from a callus/suspension culture generally have the … Read more DMPQ- Explain the main Applications of tissue culture.

Applications of hydraulic pressure Hydraulic Lifts and Fluid Power Blaise Pascal derived a law that explains how people can harness the power of fluids. When you apply pressure to liquid in a confined container, that pressure transmits equally to all other points in the container. According to the law, it’s also possible for a hydraulic … Read more DMPQ- Mention the Applications of hydraulic pressure
