Biology is studying everything about life and its participants. What do you know about life and its participants? From cells, photosynthesis, ecology, botany, evolution, genetics, DNA to viruses and bacteria, biology is undoubtedly one of the most interesting subjects.
Thanks to biology, we understand how food moves from the mouth all the way to the small intestines, how many bones an adult human has, how important carbon dioxide is for that beautiful green plant on your balcony, and many other things.
