Question: How would you characterize cancerous tissue in terms of how long the cells spent in the different stages of the cell cycle? How would you demonstrate that this cancerous tissue is different from non-cancerous tissues? (I don't know why this got taken down but PLEASE HELP)

the process by which green plants and some other organisms use sunlight to synthesize nutrients from carbon dioxide and water. Photosynthesis in plants generally involves the green pigment chlorophyll and generates oxygen as a by-product.

the solute can move "downhill," from regions of higher to lower concentration, relying on the specificity of the protein carrier to pass through the membrane. this process is called passive transport or facilitated diffusion, and does not require energy.
