How do humans interact with the atmosphere?
How do humans interact with the atmosphere? There is substantial evidence that human activities, especially burning fossil fuels, are leading to increased levels of carbon dioxide and other greenhouse gases in the atmosphere, which in turn amplify the natural greenhouse effect, causing the temperature of the Earth’s atmosphere, ocean and land surface to increase … […]
What is perturbation technique?
What is perturbation technique? A mathematical technique to eliminate linear terms in an equation in order to retain the nonlinear (turbulence) terms. Variables such as potential temperature (θ) or velocity (U) can be partitioned into mean (slowly varying) and perturbation (rapidly varying) components. Why do we use perturbation? Perturbation is used to find the roots […]

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 […]
