Answer:
Ethanol is most likely to be a (B), competitive inhibitor.
Explanation:
The poisoing occurs because of the harmful metabolites produced by the alcohol dehydrogenases, enzymes in charge of breaking down alcohol. 
Hence, the most likely strategy of an antidote is to compete for the active site of the enzyme and prevent the methanol convertion to harmful chemicals. 
Ethanol does not produce these metabolites and it is preferentially proccessed by the body, so it is a competitive inhibitor, competing for the active site.

Answer:
The correct answer is option C. 
Explanation:
The masses of air move from the areas of high pressure to the areas of low pressure. Pruitt's city must be situated more or less within the equator for it to be dominated by maritime tropical air mass. This area gets adequate sunlight all throughout the year because of the comparative position of the Sun.  
Therefore, its atmosphere is usually more heated in comparison to that of the Polar Regions. The air in the tropic regions turns less dense and elevates into the upper atmosphere. The cooler and denser maritime polar air mass from the poles moves in to substitute the elevating air in the tropics, thus, developing incoming cooler winds.  
This is the reason for the creation of the trade winds across the globe and distributing energy around the planet to a more or less homeostatic level.  
 
        
                    
             
        
        
        
Answer:
D.20,000
Explanation:
The Gross Annual Primary Productivity for the wetland ecosystem is the amount of carbon taken up by the aquatic producers through photosynthesis.  
Given that: Net Annual Primary Producer is 8,000 kcal/m2 per year, and respiration by the aquatic producers is 12,000 kcal/m2 per year, using the formula NPP = GPP – Respiration, we can determine the Gross Annual Primary Productivity of the wetland ecosystem.
NNP = 8,000 kcal/m2
Respiration = 12,000 kcal/m2
GPP = x
8,000 = x – 12,000 (NPP = GPP – Respiration)
Solve for x:
x = 8,000 + 12,000
x = 20,000 kcal/m2 per year
GPP = 20,000 kcal/m2 per year
 
        
             
        
        
        
The reason they don't tan is because their melanocytes are inactive.
