Swollen and/or bleeding gums are the first oral symptoms of malnutrition. As the malnutrition continues, the teeth may begin to decay. When only the gums are affected, the oral effects of malnutrition can be reversed; however, once the teeth begin to decay, the damage is permanent.
The density of milk depends on fat content and its type. The density varies from 1.032kg/L (whole milk) to 1.035kg/L (skim milk). This can go as low as 1.026kg/L under cert â¦ ain conditions, but a low density could also indicate added water.
Depending on its fat and nutrient content, milk's weight can vary a small amount. For reference, the weight of a gallon of water is 8.34 pounds, and the density of water is about 1 kilogram per liter. Since milk is between 80 and 90 percent water, even an outlier gallon sample of milk only varies a few ounces from the USDA figure.
