When studying a complex biological phenomenon, it is required to look at the workings of the various systems associated with it. The research is a top-down approach of getting down to the very detail of the cells and molecules taking part in it. Example, a person finds it difficult to digest milk and vomits it on ingestion. As we go a level down, we identify the systems getting affected by the milk. Then, further down, the cells that take in digesting the milk are identified. The enzymes that break down the substances in the milk are identified. The gene regulation of this enzyme (lactase) is studied to check its regulation. This work of doing a top-down approach to find the signalling pathway within the cells to identify the problem with the working of lactase to digest milk, is a necessary approach.
Based on the research of Albert Einstein the best way to increase energy of emitted electrons when using red light is to use a different colored light that has a higher frequency. Albert Einstein has proved that t<span>he energy of the emitted electrons depends only on the frequency of the incident light, and not on the light intensity.</span>
That is true. Burning fossil fuels accelerates the carbon cycle.
