Estimate the size of the specimen using your knowledge of field of view. write formula, plug in the values, and solve

Answer and Explanation:

Size of the cell=diameter of field in цm/number of cells across the field

Example:

A student observed a row of 16 epidermal cells in a microscopic field that was 800цm in diameter. Calculate the average length of each cell.

size of the cell=8000цm/16

                       = 500цm.

stratosphere: as the altitude increases, the air temperature increases. the stratosphere has a layer of ozone, called the ozone layer. this layer absorbs most of the ultraviolet radiation from sunlight. this results in the stratosphere being warmer.
