Biological Sciences

Some of the biology courses entail dissection of animal or plant material. Such dissection is an essential component in the learning of biological principles and is required of all students majoring in the Biological Sciences at UNO and of all students matriculating in the upper-level biology courses. It is recognized that a significant number of nonmajor students take only the 1000-level biology courses and do not matriculate toward upper-level biology coursework. It is the policy of the department that, in the 1000-level biology courses (with the exception of Biology 1311), such nonmajor students who, for ethical reasons, object to dissection, may request of the laboratory instructor to be exempted therefrom (with the understanding that the student will be held responsible for the course material contained therein).
