How much do section scores really matter?

I’m in sort of a strange ACT spot. I’ve scored a 32 composite with a 36 English, 36 reading, 29 science, and 26 math. This was on my second attempt at the test.

My problem is that I want to major in biology and later genetics at a good school. My composite is good, but I’m worried about my math score. I’m doing practice tests almost every day and I can’t seem to score higher than a 27. My parents really want me to get a 30 on the math section so it doesn’t look like such a weakness but I think I’ve maxed out. Do colleges really care what my section scores are, or does it not matter if you have a good composite? I’m very worried about this!
