Biology Quiz: Toughest Trivia! Exam - Quiz

Are you ready for this most challenging biology quiz? Biology is responsible for so many great things. Food is derived from plants and animals that, to some degree, are created because of the knowledge of biology. Farming, crossbreeding, and genetic engineering methods have helped improve production, eliminate weak and undesirable characteristics, and establish disease-resistant varieties into crops, fruits, and vegetables. This extraordinary quiz will tell you how advantageous biology is for everyone.
