It was borrowed from the school library and confiscated by the teacher. You are not directly responsible. First, you can apologize to the biology teacher or write a letter of guarantee. If he still refuses, you can ask the library teacher to help you. Finally, if it really doesn't work, you can directly find the dean or something, which is one level higher than your class teacher anyway. The head teacher is already a problem, and the confiscation of books by biology teachers for no reason is also an invasion of students' privacy and an injury to students' self-esteem. Pay attention to be well-founded and have a good attitude. It is best to admit your mistakes when allocating the second and third types. It is best if you can have a classmate to prove that you didn't read in class.
