Answer:
Phylogenetics
Explanation:
An evolutionary tree can also be called a phylogenetic tree, or a just a phylogeny, and phylogenetics is the study of determining evolutionary relationships, or patterns of descent of organisms.

This would negatively impact the native bird species and the fish population as well as any other underwater species such as smaller fish and algae as they may have overgrowth and could even become an invasive native species over time because the food chain would be disrupted. The native bird species wouldn’t have much food supply and would either die off or migrate to another place, and the feeder schools of fish (large fish) would probably also eventually die off because they would be over dominated with multiple species feeding off of them. The natural food chain already established would be disrupted.
        
             
        
        
        
Answer:
0 = -2, hence no solution.
Explanation:
4x + 2(x-5) = 3(2x-4)
4x + 2x - 10 = 6x - 12
      6x - 6x = -12 + 10
                0 = -2
 
        
             
        
        
        
Answer:
B. So you can always see the entire object at the higher magnification
Explanation:
A microscope is used to view objects smaller than the naked or unaided eyes can see. The objective lens, in conjunction with the occular or eye lens, is used to achieve this purpose. The objective lens are of different magnifications as follows: 10X, 40X, 100X etc. 
However, as the magnification increases i.e. higher objective, the object in the field of view becomes smaller and less focused. Hence, the object in the field of view must first be centered at a lower magnification/objective lens before changing to a higher one in order for the entire object to be seen at a higher magnification.
