Answer:
I think its C a scientific journal article
Explanation:
Any kind of journal is considered a primary source because  journals contain info that the original author wrote. Encyclopedias are considered teritary sources, but im not sure if that counts ...so id go with journals.
 
        
                    
             
        
        
        
Answer 2, because when you add salt to something, it cools faster (ex. When you add salt to an ice chest so that it stays cold) and it takes longer to boil (ex. When you boil salt out of ocean water so that its safe to drink) therefore, the more NaCl in the solution, the more it will exibit these properties
        
             
        
        
        
Answer: There are 78.26 mL of a 0.0023M strontium hydroxide solution are needed to completely react 15.0 mL of 0.012M hydrochloric acid.
Explanation:
Given:  = 0.0023 M,
 = 0.0023 M,           = ?
 = ?
 = 15.0 mL,
 = 15.0 mL,            = 0.012 M
 = 0.012 M
Formula used to calculate volume of strontium hydroxide solution is as follows.

Substitute the values into above formula as follows.

Thus, we can conclude that there are 78.26 mL of a 0.0023M strontium hydroxide solution are needed to completely react 15.0 mL of 0.012M hydrochloric acid.
 
        
             
        
        
        
Answer:
The correct answer is 1 NADH is generated by the oxidation of glucose-6-phosphate.
Explanation:
Pentose phosphate pathway deals with the utilization of glucose-6-phosphate by oxidation process to form 6-phosphogluconolactone by the catalytic activity of glucose-6-phosphate dehydrogenese.
    This enzyme need NAD+ as co enzyme which get reduced to generate NADH.
