Biology exam: MCQ ultimate quiz! Biology is the study of living things. It helps explain the processes that go on within the living creatures and how they behave in the environment they live in. Do you know how many systems exist in the human body and some of the threats the body faces from the environment. Do take up this See morequiz and see how much you know about living things.
