You should go to khanacademy.org, click on Subjects, then find Biology.
Study and learn.
I understand that you need help with biology, particularly the Biology B course. While I cannot personally take the course for you, I can certainly assist you in understanding the subject. To get started, please provide me with specific questions or topics within biology that you are having trouble with. That way, I can explain the concepts and guide you on how to find the answers.
