Egg is the reproductive body laid by the female encased in a round or oval shell. The egg consists of the thick, clear white (albumen), approximately 60% of total weight of egg, and a yellow yolk, approximately 30% of total weight of egg.The white is 87% water and 10% protein. The protein in egg whites coagulate at 150 degrees F (65 degrees C).The yolk consists of 50% water, 16% protein and 32% fat. The protein in the yolk coagulates at 158 degrees F (70 degrees C). Eggs, as well as flour, are the structural ingredients in baking.he white is 87% water and 10% protein. The protein in egg whites coagulate at 150 degrees F (65 degrees C).

When we make jokes about tortoises being slow, we mean slow! GalÃ¡pagos tortoises amble along at an astonishing 0.16 miles per hour (.26 kilometers per hour). Humans walk at an average speed of 2.8 miles per hour (4.5 kilometers per hour).
Some claim T. rex could run at speeds up to 72 kilometers (45 miles) per hour. But biomechanics researchers argue that the animal moved much more slowly, perhaps only about 16 kilometers (10 miles) per hour--about as fast as an average human runner. These experts say size slowed T. rex down. But why is it so hard to be big and fast?
