Lets suppose you prepared a simple stained slide out of a plate culture. During observation you noticed a lot of stain particles which created problems in identifying the bacterial cells accurately. How could you minimize this error the next time you make a slide

answer:

convection currents in the magma drive plate tectonics. heat generated from the radioactive decay of elements deep in the interior of the earth creates magma (molten rock) in the aesthenosphere. the aesthenosphere (70 ~ 250 km) is part of the mantle, the middle sphere of the earth that extends to 2900 km.

the contamination

we are putting to many trash.

colors do exist. the color of the sky is actually violet; humans percieve the color of the sky as blue.
