Proteins are made from amino acids. An amino acid has three parts that are joined to a central carbon atom. Identify the three parts that create an amino acid. amino group fatty acid carboxyl group R group C group A chain of 2 carbon atoms and a nitrogen atom is shown. The middle carbon atom is bonded to a hydrogen atom and an R group. The other carbon atom is double-bonded to an oxygen atom and single-bonded to a hydroxyl group. The nitrogen atom is bonded to 2 hydrogen atoms.

amino group, fatty acid carboxyl group and R group.

Explanation:

The three parts from which amino acid is formed are the amino group, carboxyle group and R group. These amino acids are the building block of proteins. There are certain foods which contain proteins such as meat and pulses etc. When these foods are eaten, the protein broken down into amino acid with the help of enzymes and absorbed by the cells for building of muscles and other substances in our body.

population. population is the number of people or animals in a particular place. an example of population is over eight million people living in new york city.

here is your answer hope i .

the answer is true when observing or determining population size, a direct observation is use, in which each organism is counted in a population or in an area. one benefit of this measure is that you get the exact population count but it will take a long time to  determine  the  size  of a  population.
