Answer:
Oceans, seas and other types of large rivers and lakes can effect the climate of the near-by proximity areas. The water in the oceans tend to heat and cool more slowly than land masses. As a result, the proximity near the oceans tend to stay cooler  during the summers and the water in the oceans is more heated. These areas will stay warmer during the winters while the water in the oceans will remain cooler. 
 
        
             
        
        
        
Answer:
A.
Explanation:
The correct sequencing of DNA nucleotides to match A, T, T, G, C is T, A, A, C, G because the nucleotide matches are: Adenine-Thymine, and Guanine-Cytosine. This works both ways, A-T or T-A, and G-C or C-G. The correct sequence therefore is A.
