Biology concepts + study methods: Circulatory system Part 1

Hypothesis is skill to predict future. There is no right or wrong answers. To learn how to predict future logically, you will need to practice by making logical connections. It could turn out to be right but many times wrong. But it is not the point. If you predicted not accurate enough, you can improve.

This is how you train yourself to predict unknown.

The circulatory system lectures (probably 3 in total) will show you how.
