<p>You have to know a good deal about both to do anything useful in the life sciences. I’m an ecology major (read) and I still had to take two terms of organic chemistry, and for veterinary school, I will also have to take biochemistry. On top of that, I had to learn some radiochemistry because I work with radioactive isotopes in an endocrinology lab. I think there are more similarities than differences. After all, biology’s foundations are in the characteristics of chemical compounds, reactions, and energy transfer (to which a physics major would reply, which are based upon the laws of physics, and then I’d award him or her the tri-cornered hat of “Captain Obvious”)</p>
