Explanation:
Another example-When rolling a ball down a ramp the ball at its highest point has potential energy but when it rolls down the ramp it converts to kinetic energy
Hope this helps :)
The 5 ounces of beef strip steak would count as 5-ounce equivalents in the Protein Foods Group.
Al the foods made from poultry, meat, seafood, peas and beans, eggs, processed soy products, seeds, and nuts are regarded as the component of the Protein Foods Group.
Steak, like any other animal product, is a rich source of protein. A 5 oz serving of steak gives 38 grams of protein, more than 6 times of the amount in one egg. The proteins help in repairing muscles and other tissues and also helps in building muscles.
