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.

What is population density?</h3>
The density of individuals within a species in a given geographic location is referred to as population density. Data on population density can be used to calculate demographics and examine interactions with ecosystems, human health, and infrastructure.
The population density equation below can be used to calculate the population density of a piece of land:
Population Density = Population/ Area
The residential density is important in determining the people's thinking and culture. Engineers find it vital to forecast population growth in order to develop infrastructure that can support a large population. It is practically impossible to develop a perfect 3D model of any structure that allows the largest number of people to live without this understanding.
