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.

Explanation:
Cell specialization is also called cell differentiation. Through this process, specialized cells form from the unspecialized cells. Then many cells are formed and determined to form specialized functions.
The stem cells are the unspecialized cells which form a different kind of specialized cells.
The muscle cells, nerve cells, sperm cells, red blood cells are specialized cells perform different specialized functions. All these cells arise from stem cells. The nerve cells receive impulse, muscle cells can contract, etc.
There are certain inductive signaling genes that send the signal to the differentiated cells. These signaling molecules are called ligands. These ligands move to another cell to produce specialized cells. In other words, there are some transcription factors and genes responsible for such cell differentiation and the formation of specialized cells.
Another example is zygote, which is an unspecialized cell. This is also a totipotent cell that has the potentiality to reproduce different cells.
