Biology - Multiple Choice Questions (MCQ) with Answers - Part 4

Biology Science Multiple Choice Questions Part 4 Eduhyme

By the 1800s, the collecting and classifying activities of Natural History were becoming more and more replaced by the experimental method. Before life, and even before the planet Earth, the Universe or Cosmos began as a “Big Bang.”

This article is for people who want to get acquainted with the concepts of basic biology. It can serve as a supplemental text in a classroom, tutored, or home-schooling environment. It should also be useful for career changers who need to refresh their knowledge of the subject.
