Codominance is when the two parent phenotypes are expressed together in the offspring. An example is a white flower and a red flower producing offspring with red and white patches.
        
                    
             
        
        
        
Refined grain products like bread, flour tortillas, white rice, cornmeal, crackers etc are enriched with riboflavin, niacin, iron and thiamin. 
Enriched grains is finely ground endosperm of the kernel. Enriched grain products are good as a source of iron and four types of vitamin B which includes niacin, thiamin, folic acid and riboflavin and also contains some complex carbohydrates.
Wheat and rice are a staple diet in many regions of the world but excessive polishing and refining the cereals removes the essential nutrients or vitamins which have their own important physiological roles.
 
        
             
        
        
        
Answer:
A. The bacteria could no longer regenerate the NAD+ needed for glycolysis, so it would stop producing ATP.
Explanation:
According to the given information in this question, Lactobacillus acidophilus is a bacterium species that uses the lactic acid fermentation when there is no oxygen in its cell i.e. under anaerobic conditions. This means that it converts glucose to lactic acid during this anaerobic respiration process. 
However, if the lactic acid fermentation pathway were blocked under an anaerobic condition, this means that it will be no longer be able to perform respiration and hence stop production of ATP. This is because the bacteria will no longer regenerate the NAD+ (electron acceptor) needed for glycolysis, so it would stop producing ATP. Note that, all living organisms, whether aerobic or anaerobic, undergo GLYCOLYSIS, which is the first stage of cellular respiration.
 
        
                    
             
        
        
        
The value of the unknown number is 10.5.
Let the unknown number = x
When 20 is subtracted from the number and the result is squared which is equal to the square of the unknown number minus 20:
 (x - 20)² = x² - 20
<em>expand the equation;</em>
x² -  40x  +  400 = x²  - 20
<em>collect similar terms together;</em>
x² - x² - 40x = -20 - 400
-40x = -420

Thus, the value of the unknown number is 10.5.
