Answer : The correct option is, 
Explanation :
Amino acid : The acid that contains two functional groups that are carboxylic group,
and ammine group,
.
When the two or more that two amino acids join together with the help of peptide bond, they produces polypeptide chain or protein.
The bond present between the two amino acid is called a peptide bond.
The peptide bond is a chemical bond that is formed between the two molecules when the nitrogen of one amino acid react with the carbon of another amino acid by releasing a water molecule. This is a dehydration synthesis or condensation reaction.
From this we conclude that, only two functional groups carboxylic group,
and ammine group,
are present in all amino acids.
Hence, the correct option is,

Hello!</h2>
The answer is:
The new volume will be 1 L.

<h2>
Why?</h2>
To solve the problem, since we are given the volume and the first and the second pressure, to calculate the new volume, we need to assume that the temperature is constant.
To solve this problem, we need to use Boyle's Law. Boyle's Law establishes when the temperature is kept constant, the pressure and the volume will be proportional.
Boyle's Law equation is:

So, we are given the information:

Then, isolating the new volume and substituting into the equation, we have:



Hence, the new volume will be 1 L.

Have a nice day!
Because the Earth's orbit around the sun is not in the same plane as the Moon's orbit around the Earth.
Answer:
A delta is formed when the river deposits its material faster than the sea can remove it. ... Cuspate - the land around the mouth of the river juts out arrow-like into the sea. The Ebro Delta. Bird's foot - the river splits on the way to the sea, each part of the river juts out into the sea, rather like a bird's foot.
