Both isotonic and isosmotic refer to the strength of the solution,  for example, how much solute is dissolved in the solution. Isotonic  refers to the ionic strength of a soâ¦lution while isosmotic refers  to the number of molecules of solutes in a biological solution, for  example, sugar concentration.
The egg is strongest from point to point and easily crushable at the sides. Breaking an egg with steady equal pressure at each end of the egg is remarkably hard to do when considering the thin shell involved.
The yellow part of the egg, which is called the yolk, contains a high level of saturated fat, cholesterol and calories but it also has a fair amount of protein as well. However, the Biological Value (BV) of a whole egg is actually 100 which is the highest rating of any protein source. The yolk also has most of the eggâs nutrients and contains about 22 grams of calcium, 18 IU of Vitamin D and 25 mcg of folate. If you are cutting calories and trying to get really lean, then you might want to limit your intake of egg yolks and stick with just the egg whites.
