- Cyanobacteria are found in the ocean and are believed to be responsible for the formation of the iron oxide found on the sedimentary rocks since they release oxygen as a by product and it is used in the iron oxide formation process below the level of wave disturbance.
The magnification of a specimen viewed with a compound light microscope that has an objective power of 10x and an ocular lens power of 5x is equal to 50x. Magnification is equivalent to the product of the objective power and the ocular lens. Ten times five is fifty.
Therefore, the answer is 50x
