<span>Prokaryotes don't have a nucleolus as they do not have a nucleus, and neither do they have a Golgi apparatus. A nucleoid is loose DNA which is found in prokaryotes but not in eukaryotes...</span>
Most models can't incorporate all the details of complex natural phenomena. For example, when measuring distances around the Earth it's convenient to model the Earth as a sphere, but this doesn't incorporate variations in distance because of mountain ranges, valleys and other topological features the traveler must traverse. Incorporating these additional details would make the model too complex for easy use. Since models must be simple enough that you can use them to make predictions, they often leave out some of the details.
ALSO.
The conformation of molecules are based on probability. It fails to take into account the electronegativity of individual atoms. And it is ineffective in showing inorganic interactions with metals and such.
It's the first one where it resist change in pH solutions by neutralizing :)
Answer:
Carboxyl group and amino group.
Explanation:
Amino acids have three parts which are the carboxyl group, amino group and the side chain. When forming a peptide bond, the carboxyl group of one amino acid forms bonds with the amino group of the other one to form the peptide bonds between them.
I hope this answer helps.
