Please tell me the definition for genetic manipulation |
| Answer» Genetic manipulation is a process in which genes of desirable characters are taken from a plant and transferred to another plant by the technique of hybridisation. Genetic manipulation helps in obtaining desirable agronomic characters liked Dwarfness in cereals and tallness and profuse branching in fodder crops. It is useful in developing varieties with higher yield, good quality, biotic and abiotic resistance, short maturity period, wider adoptability and desirable agronomic characteristics. | |

What is magnitude.? |
| Answer» In physics — the study of motion distance, velocity, speed and mass expressed as quantities — is divided between vectors and scalars.

Why does temperature remains constant during physical change of matter? |
| Answer» The temperature of any substance remain constant during the change of state because the heat energy supplied is used up in changing the state of matter and also this heat is used for breaking of several bonds or attractive forces.This heat, which does not raise the temperature of the body, is called Laten heat | |

What is netowns law |
|
Answer» THIRD LAW OF NEWTON every action has an equal and opposite reaction. SECOND LAW OF NEWTON the rate of change of momentum is directly proportional to the applied force. FIRST LAW OF NEWTON if the object is in rest it will remain in rest and if the object is in motion it will remain in motion until and unless an external force is applied that. There are three laws of motion 1; inertia 2; the rate of change of momentum 3; backword reaction |

What is tyndall effect?+example |
| Answer» The Tyndall effect is the scattering of light as a light beam passes through a colloid. The individual suspension particles scatter and reflect light, making the beam visible.The amount of scattering depends on the frequency of the light and density of the particles. As with Rayleigh scattering, blue light is scattered more strongly than red light by the Tyndall effect. Another way to look at it is that longer wavelength light is transmitted, while shorter wavelength light is reflected by scattering.An example of the Tyndall Effect is how the headlights of a car are not able to shine all the way through fog. Headlights cannot penetrate fog because it is a colloidal substance, meaning that fog is made up of scattered particles. When light hits a substance with scattered particles, it collides with the particles, causing the light to scatter in multiple directions.Another example of the Tyndall Effect is the way certain eyes appear to be blue. This is because the turbid layer of blue eyes contains less melanin, a substance that absorbs light. With less melanin, wavelengths of light can pass through the turbid layer. The shortest lightwave reflects a blue color, so this is the color the eye appears to be. | |
