Answer:
Because it is a fluid system, the atmosphere is capable of supporting a wide spectrum of motions. These range from turbulent eddies of a few meters to circulations with dimensions of the Earth itself. By rearranging mass, air motion influences otheratmospheric components such as water vapor, ozone, and cloud, which figure prominently in radiative and chemical processes. Such influence makes the atmospheric circulation a key ingredient of the global energy budget.

Answer:
Nucleotide bases.
Explanation:
Unique sequences of bases makes up a nucleotide. These nucleotide sequencing are used by DNA as a genetic code of information that determines type of cells, proteins and the whole organismal structure. 
There are four nucleotide bases, Adenine and guanine termed purines are big, cytosine and thymine called pyrimidines are small. A purine pairs with a pyrimidine, such that adenine pairs with thymine and guanine pairs with cytosine. The bases are the same but each DNA uniqueness lies in the sequence of base pairing.
 
        
             
        
        
        
<span>Answer: a. Citizens over the age of 65 use social media primarily to follow the activities of their families. </span>
<span>More than half of the citizens over 65 say that they have a social media account. They read other postings but post information about one-fifth as often as they read posts.  Most of their feeds consist of posts by relatives. From this passage, we can logically say that  Citizens over the age of 65 know how to use the social media and they use it primarily to follow the activities of their families. </span>
