parallel.
he large diversity of shapes of biological molecules is possible because of the extensive
presence of _____ in the molecules. - ANS-Carbon
The type of bonding and the numbers of covalent bonds an atom can form with other
atoms is determined by _____. - ANS-the valence

nitrogenous base; and a phosphate group? - ANS-DNA

reticulum (Smooth ER) and rough endoplasmic reticulum (Rough ER)? - ANS-The
