Answer:
proteins
Explanation:
proteins increase metabolism and repairing damaged cells
 
        
             
        
        
        
In broad terms, finches. In specific terms, he observed how over time, the beak sizes and shapes of said finches changed to adapt to the food sources available. 
I hope I was able to help. Best of luck.
        
             
        
        
        
The correct answer is: Layer 1, layer 2, and layer 4 in all three regions.
The index fossils are fossils that are commonly used for identifying a geological period of time, and these fossils are also very wide spread, as well as having a rapid evolutionary trends. 
By this picture, we can easily see that even though we have rock strata from different regions, the same layers contain the same fossil, and it is a fossil that also is rapidly evolving so has a minor change in each layer.
 
        
             
        
        
        
Answer: they damage proteins and DNA 
<span>Oxidative stress and other cell processes induce the formation of highly reactive aldehydes that react directly with DNA of a microbial organism, forming aldehyde-derived DNA </span>adducts lead to proteins and DNA damage. DNA damage causes deregulation of cell homeostasis and thus contributes to the disease phenotype.
