hey kid, there is not much you can do at 14 years old in the biology domain, but you can read as much as possible and make your own observations in nature. That what I did until I reached the age to study it serously. It really made me love biology and become motivated to study hard. ;)

Here's my opinion. I'm a future biologist and I thought about this many times... There is proof that most basic organic molecule can be created in the athmosphear or underwater. It is statistically possible that simple life like system auto-assemble in natural conditions, it happened here after all....

Each eye contains two cristallins. This allows the fish to look outside the water watching for danger and at the same time lo...

What I can tell you is that human hemoglobin proteins are made of 4 heme units each containing an iron atom that is necessary to oxygen grabbing. Perhars you should compare human and lama hemoglobin proteins to find out if they have different properties, just like that guy said before, high altitude...

Indeed O2 is involved in many more ways that you think in the krebs cycle. Never forget that when you look at the cycle there is casacades of reaction between every molecule. Some of those reactions are oxydoreduction. It is a process in wich electrons are passed from a molecule to another that has ...
