difference between bio dagrable and non biodagrable material give example |
| Answer» Key Differences Between Biodegradable and Non-biodegradable\tBiodegradable substances are those which decompose naturally in the environment naturally and are considered beneficial for the environment. The natural agents involved in the degradation are air, water, microorganisms, sunlight, soil, etc.\xa0Non-biodegradable\xa0substances are those wastes which do not decompose naturally in the environment, causes pollution and are also harmful to the living being.\tExamples of biodegradable substances are dead plants and animals, their waste, fruits, vegetables, flower, paper, etc., while non-biodegradable substances include chemicals, paints, plastic, rubber, toxic, plastic, metals, etc.\tThe rate of decomposition of biodegradable substances is high or fast, which completes within few days or months, whereas the non-biodegradable items either do not decompose and maintain their originality, even their decomposition is so slow that it may take thousands of years.\tBiodegradable substances after degradation can be used to\xa0produce biogas, manure, fertilizers, compost\xa0and thus they are profitable to the environment even after degradation. But in non-biodegradable substances the degradation rate is slow, and the separation and recycling are not easy, even expensive too and is not beneficial to the environment. | |

Explain : Feedback mechanism |
| Answer» Feedback mechanism is a mechanism that tends to initiate (accelerate) or to inhibit (slow down) a process. Feedbacks mechanisms help regulate biochemical pathways.

Why is the colour of sky is blue |
|
Answer» Each color of light has a different kind of wave, from short wavelengths to long wavelengths. For example, blue light has a shorter wavelength than red light. blue light is scattered in all directions by the tiny molecules of air in earth\'s atmosphere.Blue is scattered more than other colors because it travels as shorter,smaller waves. The molecules of air and other fine particles in the atmosphere have smaller size than the wavelength of visible light. These are more effective in scattering light of shorter wavelengths at the blue end than light of longer wavelengths at the red end. The red light has a wavelength about 1.8 times greater than blue light. Thus, when sunlight passes through the atmosphere, the fine particles in air scatter the blue colour (shorter wavelengths) more strongly than red. The scattered blue light enters our eyes. |
