Difference between essential and non essential amino acids relate this to complete and incomplete proteins

Here's what I find.  

Explanation:

Essential amino acids are those that the body cannot make. It must obtain these amino acids from food.

Nonessential amino acids are those that our bodies can produce, even if they are not in the food we eat.  

A complete protein is a food source that contains all the essential amino acids. Examples are eggs, dairy, fish, and meat.

An incomplete protein is a food source that contains some but not all the essential amino acids. Examples are legumes, nuts, seeds, and whole grains.

the cladogram shown here shows similarities and differences among several classes of vertebrates. anatomically, the four have limb structure as their common ancestor. we might separate the mammals from the other three classes because they a) divergent; do not lay eggs b) identical; are warm-blooded c) varied; a four chambered heart d) homologous; have mammary glands
