Explanation:
they used the amino acid to find the DNA base sequence
 
        
             
        
        
        
Overproduction - An organism gives birth to too many children 
Genetic Variation - The offspring each have genetic differences in appearance, behavior, etc
Struggle to Survive - Offspring must fight in order to gain essential resources (food, water, mates, etc)
Successful Reproduction - Organism produces offspring with beneficial adaptations that aid in survival
 
        
             
        
        
        
<span>A warm front is the boundary between a warm air mass and a cold air mass it is overtaking. So a cold front would be the opposite.

There is more to DNA than cytochrome c. This is just one protein.
 
        
             
        
        
        
The right answer is D) 9 groups of 3 microtubules
Centrioles are the constituents of a so-called centrosome structure: every animal cell has a centrosome, which is made of two centrioles and which together form a functional unit. A centriole consists of nine triplets inclined microtubules, surrounded by a number of proteins.
