Biology Practice Test Questions! Trivia Quiz

Biology is essential to every-day life because it allows humans to understand better their bodies, their resources, and potential threats in the environment. Biology is the study of all living things, so it helps people to understand every living organism. Biology is also an important subject in school. This quiz will determine how well you know biology.
