Explanation / Answer

17. Carbon can form maximum of four bonds with other molecules. C-C bond are very strong. So, the correct answer to this question is option D. The strong covalent bonds between two Carbon atoms are responsible for the stability of long carbon chains and make them ideal for the long biomolecules.

18. A protein motif is a supersecondary structure which is a protein structure formed by the spatial arrangement of amino acids in a combination of one or more than one type of secondary protein structures like alpha helix, beta sheet. etc. For Example: Zinc Finger, Leucine Zipper etc.

19. Cross bridges that stabilize the tertiary protein structures are formed between two sulphur molecules that are part of sulfhydryl groups. So, the correct answer for this question is option 'E'.

20. The hydrophobic or hydrophillic nature of molecules is dependant on the nature of bonds that are formed between them.Being hydrophobic means, the capacity of molecules to repel water. The covalent bond between hydrogen and carbon in hydrocarbons are non-polar in nature, the electrons are equally shared between hydrogen and carbon atoms. So, these molecules easily dissolve in nonpolar solvents but not in polar solvents like water.

Hence the correct answer to the question is option 'A'.

Since the questions before Q17 are already answered, I have assumed that those are not needed to be answer by me.
