The diameter of a cell is 40 um. You want to make a model of this cell where 1 cm represents 0.5 um. What would be the diameter of the model cell?

The diameter of the model cell would be 80cm.

Explanation:

We know that 1 cm represents 0.5 μm, but we need to know how many centimeters are 40μm. To do so, we apply the simple rule of three:

So if 1cm= 05μm, 40μm would equal to how many centimeters?

1cm X 40μm = 80cm

0.5μm

We can see that the diameter of the model cell would be 80cm.

the relative standard reduction potential of the half-cell in which reduction occurs; more positive than the other half-cell. reduction is a chemical process in which electrons are added to an atom or an ion; it always occurs accompanied by oxidation of the reducing agent.
