If I should go to work or not.
This is in accordance to the number of calories each gram of macronutrient has. 1 gram of carbohydrates contains 4 calories; 1 gram of protein contains 4 calories; and 1 gram of fat contains 9 calories; (nice to know: 1 gram of alcohol contains 7 calories). In this case, the sandwich contains 460 wherein there is 6 grams of saturated fat. This 6 grams of saturated fat is equal to 54 calories. Converting that into percentage: (54 calories of fat)/(460 total calories) x 100 = 11.74% or roughly 12% of calories are from saturated fat.
I don't completely understand the question, but I am guessing that you are trying to finish the sentence. If so, the answer is "Diffusion continues until the concentration on both sides of the membrane is <u>equal</u>". The reason it's equal is because diffusion always travels high to low, to reach a point of equilibrium. The particles are trying to move so that water is the same inside and outside of the cell/membrane, and the solute is also equal on the inside and outside of the cell/membrane. If that doesn't make sense, just comment any questions you have and I will try my best to answer :)
