Organelles are composed of various organic compounds, such as proteins and lippo-proteins.
Different sequences of amino acids and possibly different numbers.
Chromosomes are composed ofDNAHistone proteins
Organisms can synthesize proteins or get them in their diet.

thousands of different proteins
DNA and Proteins. Chromosomes in organisms are composed of DNA and protein
That depends on the specific protein, there are many thousands of different proteins each with different actions.
Organelles are composed of various organic compounds, such as proteins and lippo-proteins.
proteins, just like in all the other organisms.
Proteins are molecules that feed living organisms. There are about twenty different kinds of proteins. Proteins are found in foods.
Ribosomes are composed of special proteins and nucleic acids. A eukaryotic ribosome is composed of nucleic acids and about 80 proteins. About two-thirds of this mass is composed of ribosomal RNA and one third of about 50+ different ribosomal proteins.
water
Yes. Remember that when 2 atoms of the same or different elements combine, it forms a molecule. 2 hydrogen atoms + 1 Oxygen atom = 1 molecule of H20(water). The same holds true for proteins, proteins are composed of amino acids, which are in turn composed of different molecules, which are also composed of different atoms.
No, they are composed of Amino acids.
