The population of their prey most likely increased causing an imbalance in the food chain. This is true since there probably was not enough food to feed the rapidly increasing population.

YES.The distribution of bases in sea urchin DNA and salmon DNA follow Chargaff's rules because the percentage of A bases is approximately equal to the percentage of T bases, and also the percentage of G bases is approximately equals to the percentage of C bases in both species. According to Chargaff's rule the amount of guanine should be equal to cytosine and the amount of adenine should be equal to thymine. 
        
             
        
        
        
Yes, because each of the four nucleotide bases present in DNA have a corresponding base: adenine bases always pair with thymine bases, and cytosine bases always pair with guanine bases. For example, if one strand of a DNA molecule was CTAGGT, the sequence of the second strand would be, from left to right, GATCCA. 
        
             
        
        
        
Answer:
Hello there, I will give the answer
Explanation:
Aquatic plants require special adaptations for living submerged in water, or at the water's surface. The most common adaptation is the presence of lightweight internal packing cells, aerenchyma, but floating leaves and finely dissected leaves are also common.
