A) why are some molecules polar and others nonpolar? (1 point)

Some of them don't produce enough energy. These are called Polar Molecules.

Explanation:

some molecules are polar because they have an unbalanced electrical charge because of their bent shape or they don't share electrons equally between their atoms

while other molecules are nonpolar because they have a balanced electrical charge cause they do not have a bent shape and share electrons equally between their atoms.

Explanation:

some are polar while others are nonpolar because of the way their electical charge is arranaged within themselves.

you know they are heterozygous for a trait because they have it as jj or jj.
