What is the first step in phosphorus cycle? Weathering. Since the main source of phosphorus is found in rocks, the first step of the phosphorus cycle involves the extraction of phosphorus from the rocks by weathering. Weather events, such as rain and other sources of erosion, result in phosphorus being washed into the soil. What […]

How do you calculate the surface area to volume ratio of cells?
How do you calculate the surface area to volume ratio of cells? To calculate the S/V ratio, simply divide the surface area by the volume. We will examine the effect of size, shape, flattening an object, and elongating an object on surface-to- volume ratios. To perform this function efficiently, there must be an adequate ratio […]
