<span>The discovery of the Cell Theory has greatly impacted
modern science. It proves that every living thing on Earth is made up of
one or more cells. It impacted modern science because now scientists
can find out more about organisms that they couldn't have if they didn't
know about cells. Because of this, scientists don't have to worry about
lack of understanding the organisms. In fact, there are two different
types of organisms, prokaryotic and eukaryotic. Prokaryotic organisms
are those which only contain a singular cell. For instance, bacteria are
prokaryotic. Eukaryotic organisms contain more than one cell, such as
plant and animal cells. These have a membrane surrounding their nucleus
as well as one surrounding the cell itself. In conclusion, the cell
theory has helped scientists successfully study cells and their
functions using microscopes and other advanced technology.

Answer:
C and D
C. There must be 80- 100 inches per year
D. No rain must be distributed throughout the year ;)
Explanation:
Answer:
D) 3.51x10²³ formula units
Explanation:
To know this, we need to calculate the molecular mass of CaO. To do that, let's use the atomic mass of each element of this compound.
Ca: 40.08 g/mol; O: 16 g/mol
With these given AM, let's calculate the molar mass of CaO:
Mm CaO = 40.08 + 16 = 56.08 g/mol
Now that we have the MM of CaO, it's time to determine the moles of CaO:
moles = mass / MM
moles = 32.7 / 56.08 = 0.5831 moles
Finally to get the formula units, we need to use the Avogadro's number which is 6.02x10²³. According to this number, 1 mole of any substance has this number of atoms, molecules or formula units. So, if we have 0.5831 moles, then the formula units will be:
FU = 0.5831 * 6.02x10²³
<h2>
FU = 3.51x10²³ formula units</h2>
