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.
Primary succession occurs in essentially lifeless areas while secondary succession happens where there were previous communities
Answer:
Viruses rely on the cells of other organisms to survive and reproduce, because they can't capture or store energy themselves
During interphase DNA is copied. So if there was no interphase, the new cells wouldn't have enough DNA.
Answer:
Destructive interference happens when one wave is oscillating the opposite way as the other one, so it compensates.
Explanation:
