What color bends most during refraction?
What color bends most during refraction? violet light What are two effects of refraction? The major effects of refraction of lights are: Bending of light. Change in wavelength of light. Splitting of light rays if it is polychromatic in nature. Does speed of light change during refraction? When light travels from one medium to another, […]
How does oxygen enter plant cells?
How does oxygen enter plant cells? In the natural environment, plants produce their own food to survive. As with photosynthesis, plants get oxygen from the air through the stomata. Respiration takes place in the mitochondria of the cell in the presence of oxygen, which is called “aerobic respiration”. What triggers stomata to open? Stomata are […]
What is the purpose of thin layer chromatography?
What is the purpose of thin layer chromatography? TLC is a chromatography technique used to separate non-volatile mixtures. Thin-layer chromatography can be used to monitor the progress of a reaction, identify compounds present in a given mixture, and determine the purity of a substance. What are the two major uses of thin layer chromatography? The […]

What are two examples of biogeochemical cycles?
What are two examples of biogeochemical cycles? Ecological systems (ecosystems) have many biogeochemical cycles operating as a part of the system, for example, the water cycle, the carbon cycle, the nitrogen cycle, etc. All chemical elements occurring in organisms are part of biogeochemical cycles. Is photosynthesis a biogeochemical cycle? This type of cycle of atoms […]
