Explanation / Answer

1. c) hydrogen bond

The Two main aspects which stabilize the alpha helix are intra-chain H-bonding as well as diminution of steric meddling among the side chains. H-bonds which are form among the oxygen of one peptide bond along with the amide hydrogen four amino acids which are away from it along the helix.

2. c) Lipids

Molecules which have both polar and non-polar regions.

3. c) Anaphase

The centrioles facilitate in the development of the spindle fibers which detach the chromosomes during mitosis. It happens in the anaphase of mitosis where the chromosomes go towards the different poles of the cell

4. c) spindle fibers

.
A protein structure formed by the Spindle fibers divides the genetic material in a cell. The spindle is indispensable so as to uniformly divide the chromosomes in a parental cell into two daughter cells.
