OK, now, based on this and on your request, my advice would be:
To work at a university, you will need to reach out and contact professors. Find a few who are doing research which interests you, and reach out to them. Most colleges are set up to allow high school students lab experience in active research labs. My wife works with a couple every year, she just met with two the other day, and will likely be adding one to her lab. To do this, you need to be proactive. You also will need to ask your bio teacher to write you a letter of recommendation for this, if needed.
Speak with your bio teacher about independent research.
Aside from these focused, field-related ECs, find something else that you like doing. Volunteer in a pet shelter or with homeless, try your hand at acting, art, dance, etc. Life is not only about what you are going to do in college. Find ways to make your high school years interesting and meaningful.
Good luck!
