Did I ruin my chances of getting into a decent school by getting a D in biology for a quarter grade?

I am a sophomore and I have a D I my biology class due to the fact that I bombed the last test I dropped from an A. This is only a quarter grade and the first quarter I got an A- and the second I got a B-. My parents are freaking out over it and I just want to know how badly will it affect me. I get honor roll every marking period, except this one and the last one (77% in math). Will I still be able to get into a decent college my weighted gpa before the recent quarter was a 4.400?
