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.
If you put a rock in a slingshot and draw back the rubber band the rock will fly out at a predictable speed depending on the distance that the rubber band is draw back. this is an example of the following

Answer:
Explanation:
BMR or basal metabolic rate can be define as the rate of expenditure of available energy when the body is in rest to keep the vital functions active such as breathing and circulation.
Males typically have higher BMR than females because they tend to have higher proportion of lean body mass as compared to females. The females as compared to males exhibit more amount of fat cells. The metabolism of fat cells is slow.
Answer:
The correct answer will be option- C.
Explanation:
The bacteria can transfer its genetic material through three processes: transformation, conjugation and transduction. The process of conjugation takes place through the formation of the conjugating tube formed of the pili, the membrane extensions of the bacteria.
These pili are known as fertility pili or F-pili as they transfer the F-plasmid or fertility plasmid from the F⁺ bacteria containing the F-plasmid to the F⁻ cells or the bacterial cells which lack the F-plasmid.
Thus, option- C is the correct answer.
