1)magnification goes by 10x (read 10 times), 100x,1000x and some goes 10,000x
2)Always focus first using lowest power possible first, switch to medium power (100x) after it's focused on low power(10x), on 100x, use the small knob to focus it more. DO NOT touch the bigger nob when in medium or high power. Switch to high power (100x) when it is focused on medium power, again focus again using the small knob on high power.

The use of prokayotes and other organisms to clean up pollutants from soil, air, or water is called Bioremedation. Bioremedation is the use of living organisms for the recovery or cleaning up of a contaminated medium such as soil, sediment, air and water. It is actually a waste management technique that neutralizes pollutants from contaminated site using organisms. examples of bioremedation related technologies are mycoremedation, phytoremedation among others.
