Would life be different if the electron were positively charged and the proton were negatively charged?

A) Yes.

B) No.

Answer is NO (Option B)

Does the choice of signs have any bearing on physical and chemical interactions?

A) Yes.

B) No.

Answer is NO (Option B)

Explanation:

Electric charges are of two general types: positive and negative, electrons are designated to be the carriers of negative charge. The charge on the proton and electron are exactly the same size but opposite. Opposite charges would still attract, and like charges would still repel in other words electrons would still repel other electrons, but protons and electrons would still attract each other. The designation of charges as positive and negative is merely a definition.

The choice of signs have no bearing on physical and chemical interactions because, proton and electron is just a name assigned to the sign as like charges repel and unlike charges attract. An atom is built with a combination of three distinct particles: electrons, protons, and neutrons. Electric charge, which can be positive or negative,  is neither created nor destroyed. The atom that has lost its equal share in the bonding electron pair acquires a partial positive charge because its nuclear charge is no longer fully canceled by its electrons.
