The answer is C, speciation. 
Let's say someone dropped 100 lions in the African savanna and 100 lions in the mountains. The mountain lions would evolve and adapt differently than the savanna lions.
The mountain lions might develop lighter fur for camouflage or larger lungs to get more oxygen from the thinner air, and the savanna lions might have to be a lot stealthier since there's no cover in the open plains.
        
                    
             
        
        
        
They destroy things that cost lots of money to repair, or they put people in hospitals, and that would cost a lot of money too.
        
                    
             
        
        
        
Answer:
In gram staining, 95% ethanol is used to destain the gram-negative bacteria but gram-positive bacteria do not get destain because peptidoglycan layer in gram-positive cell wall does not allow crystal violet- iodine complex to come out of the cell wall.
Gram-negative bacteria do not have peptidoglycan cell wall and so crystal violet comes out of the cell wall by using 95% ethanol because ethanol dissolves the lipopolysaccharide membrane of gram-negative bacteria and allow the dye to leak out.
Therefore if I forgot to apply 95% ethanol than crystal violet dye will not come out of the lipopolysaccharide cell wall of gram-negative bacteria and it will appear violet under the microscope.

Explanation:
Unicellular organisms fall into two general categories: prokaryotic organisms and eukaryotic organisms. All prokaryotes are unicellular and are classified into bacteria and archaea. Many eukaryotes are multicellular, but many are unicellular such as protozoa, unicellular algae, and unicellular fungi.
 
        
             
        
        
        
Redbeds indicate the presence o iron in the environment. Red beds are red sedimentary rocks and the color is due to the presence of the ferric oxides. Ferric oxides occur as a coating on the sedimentary grains. In between the shale and cherts, iron-rich sediments can be found.
