NOT A TEACHER
I think it is necessary here because after the AND, it is not a clause of the previous sentence but a new one has been attached to it. If you read it without the AND, you may observe that it seems as if a different piece of information has been added here, slightly losing relevance and flow. It does not add to the concept of the previous one.
Well that's only my opinion Hopefully a teacher will guide you better
