Of course, no one will act on this opinion, because it is quite illegal to just kill people, but it is true!
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.
Answer:
True. This is the case where an invasive species has reduced the genetic diversity of indigenous species.
Explanation:
- An invasive species is an exotic, foreign species that takes over a specific habitat or ecosystem and destabilizes it.
- Invasive species disrupt the food chains of an ecosystem which may lead to increase in populations of some species while reducing others.
- Invasive species compete with indigenous species for food, shelter and mates. As the indigenous species cannot reproduce properly, a reduction in their genetic diversity is the direct result.
