Answer:There are 11 nonessential amino acids.
Explanation:amino acids are monomers of proteins.proteins are made up of carbon,hydrogen, oxygen and nitrogen.there are 20 amino acids found in proteins.
Plants cam produce all the amino acids they need but animals cannot.
Essential amino acids are those that animals cannot produce by themselves and so need to obtain from their diet.there are 9 in numbers.
Non-essential amino acids are produced by the animals.they are not necessarily non-essential as the name indicates.they are 11 in numbers.

Answer:
mucosa
Explanation:
The pharynx and esophagus possesss all of the basic histological layers of the gastrtointestinal tract (GI tract). The layers are:
- mucosa - layer closer to lumen which cocnsists of epithelium, lamina propria and muscularis mucosae
- submucosa-layer of loose connective tissue with vessels
- muscularis propria-layer of inner circular and outer longitudinal muscular layers
- adventia - layer of loose connective tissue
Photosynthesis: This is a main activity permed by most plant cells where carbon dioxide, water, and sunlight are used to make glucose and oxygen. This process is especially important for all living organisms since glucose is a main source of cellular energy.
Cellular respiration: This activity takes glucose and breaks it down so that cellular energy can be made. If cellular respiration is not performed by any cell, they will have a hard time living and thriving.
Mitosis: This activity is where a parent cell divides into two identical daughter cells. It is important for the cell to have identical copies of every organelle and genetic information to complete this process.
Cleaning, Storing, and Building: These, and many more, are some of the other activities performed by a plant cell that help maintain homeostasis. The cells organelles are constantly cleaning up waste, storing necessary nutrients and genetic information away, and building new proteins that will help other
