Answer; 
b. nitroglycerin may give incomplete or no relief of myocardial infarction pain.
Two conditions related to cardiac compromise are angina pectoris and myocardial infarction. In comparing the two, remember that nitroglycerin may give incomplete or no relief of myocardial infarction pain.
Explanation; 
-Angina pectoris is the chest pain or discomfort due to coronary heart disease. It occurs when the heart does not get enough blood, due to blockage or narrowing of one or more heart's arteries. 
-Myocardial infarction occurs when there is decreased blood flow or stoppage to a part of the heart, resulting to the heart muscle damage. 
-Nitroglycerin extended-release capsules are used to prevent chest pain (angina) in people with a cardiac compromise. However, Nitroglycerin may give incomplete or no relief of myocardial infarction pain.
 
        
             
        
        
        
In making an experiment their are two types of variable that should be consider, one is the dependent variable and the other one is the independent variables. I the question that dependent variable would be the result or the effect of the gender of mice and the independent is the ways in determining it. So the variables should be fair if you want your result to have no bias. Thus the answer would be letter B. because it has the same variables but different in gender 
        
                    
             
        
        
        
Answer:the nucleus
Explanation:mRNA is synthesized in the nucleus using the nucleotide sequence of DNA as a template. This process requires nucleotide triphosphates as substrates and is catalyzed by the enzyme RNA polymerase II. The process of making mRNA from DNA is called transcription, and it occurs in the nucleus
