India’s latest communication satellite GSAT-30 was successfully launched from the Spaceport in French Guiana. With a lift-off mass of 3357 kg, GSAT-30 will provide continuity to operational services on some of the in-orbit satellites. GSAT-30 derives its heritage from ISRO’s earlier INSAT/GSAT satellite series and will replace INSAT-4A in orbit. GSAT-30 has a unique configuration … Read more DMPQ- Comment on the utility of recently launched satellite GSAT-30.

Reflex action is an immediate involuntary response to a stimulus. In an involuntary response, a sensory impulse on reaching central nervous system is itself returned to a specific effector as a motor impulse without neuronal analysis and integration. Reflex responses occur below the level of consciousness. Reflex actions are sudden and autonomic. For instance, if … Read more DMPQ- Explain Reflex action with examples.

Chlorine is a powerful chemical that has been in use for many years to treat water for home consumption. Chlorine is an effective water purification method that kills germs, parasites and other disease-causing organisms found in ground or tap water. Water can be purified using chlorine tablets or liquid chlorine. As an off-the-shelf water purification … Read more DMPQ- Explain the method of Chlorination for water purification.

Rather than being a mix of the two, the offspring (known as the F1 generation) was purple-flowered. When Mendel self-fertilized the F1 generation pea plants, he obtained a … Read more DMPQ: Describe in brief Mendel’s Experiments and law of inheritance

When rubbers bands are twisted and untwisted, it produces a cooling effect. This is called the “elastocaloric” effect, and researchers have suggested that it can be used in a very relevant context today. The elastocaloric effect, if harnessed, may be able to do away with the need of fluid refrigerants used in fridges and air-conditioners. … Read more DMPQ- What do you understand by ELASTOCALORIC effect?
