The correct answers are:
2) Peptide bonds form from nucleophilic attack by an electron pair on an alpha - amino nitrogen atom on an alpha - carboxyl carbon atom of another amino acid and
4) Peptides are polymers of amino acids.
A peptide bond is an amide type of covalent chemical bond. It is formed between two amino acids: C1 (carbon end) of one alpha-amino acid and N2 (nitrogen end) of another. Peptide bonds are the basis for the formation of a peptide chain and consequently protein. Formation of peptide bond is a condensation process, meaning that when two amino acids combine and link, water molecule is released and dipeptide is a product of that reaction.
Because Photosynthesis is the process used by plants and some bacteria to create energy from sunlight. ... Cellular respiration uses glucose, or sugars, from food molecules and turns them into carbon dioxide.
Hope that helped!
They are examples of runoff and and can cause acid rain. Hope this helps
I would say A is the correct answer. B and C are definitely wrong, and I think D is talking about genes and not chromosomes.
