Explaining & Analyzing Processes of Life in Biology: Practice Problems

Instructor: Artem Cheprasov
This lesson gives you plenty to think about with respect to biology. You'll get several opportunities to practice your understanding of the various processes involved in biology.

Now that you've completed the lessons in this course, use the exercises shown here to practice applying your newfound knowledge. This is not a mandatory part of your coursework but is useful practice.


Biology is not an easy topic to learn because a lot of intricate interrelationships between biological processes exist. Biology is much like the butterfly effect in the sense that one minor change in one system can reverberate throughout an entire organism or even multiple organisms. It's up to biologists to figure out how and why these changes occur.

All in all, this is why biology is best learned not through a series of specific multiple choice questions that test your memorization of facts but through questions that make you think about the big picture. If you can understand a biological process as a whole, you won't have to memorize a lot of little details. Rather, they should all fall into place.

So let's get to a few of these questions that will make you think! Not all of the questions you are about to read have a definite answer. Feel free to use outside resources to help you answer them, but try to come up with a hypothesis of your own first before seeing what some scientists think to be the correct answer.
