DMPQ: Describe in brief Mendel’s Experiments and law of inheritance

Mendel’s laws Mendel discovered that, when he crossed purebred white flower and purple flower pea plants (the parental or P generation), the result was not a blend. 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- Write a short note on NISAR.

Using advanced radar imaging that will provide an unprecedented, detailed view of Earth, the NASA-ISRO Synthetic Aperture Radar, or NISAR, satellite is designed to observe and take measurements of some of the planet’s most complex processes. These include ecosystem disturbances, ice-sheet collapse, and natural hazards such as earthquakes, tsunamis, volcanoes and landslides. Data collected from … Read more

DMPQ:Write a short note on Totipotency.

Many somatic plant cells, including some fully differentiated types (e.g. leaf mesophyll),provided they contain intact nuclear, plastid and mitochondrial genomes, have the capacity to regenerate into whole plants. This phenomenon is totipotency.Totipotent cells from plants have been used in tissue-culture techniques to produce improved plant materials that are pathogen-free and disease-resistant. Totipotent cells fromanimals are … Read more

DMPQ- Explain the method of Chlorination for water purification.

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 science behind the goal line technology.

Goal-line technology is a technical means of instantly determining whether the whole of the ball has crossed the goal line. Camera-based: Several approved systems work with cameras that detect the ball and use software to evaluate the footage from all the cameras. In this way, the system can determine whether the whole of the ball … Read more

DMPQ- What do you mean by Linear motion

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
