If the cable isn't in excellent physical shape, its data carrying capability goes down and your Internet speed will suffer. The same rule applies to its connectors and to the cable in Comcast's system as well.
Sugar is a source of carbohydrate and energy. It provides 4 calories per gram or 16 calories in a level teaspoon (4 g). This compares to 36 calories for the same amount (4 g) of fat or oil (e.g., butter, margarine, canola oil). On its own, sugar has no other nutrients.
Multiply the total grams of sugar from step 2 by four to get the total calories from sugar, because there are 4 calories per gram of sugar. For example, there are 32 calories in 8 grams of sugar, which equals 2 teaspoons.
