What do you guys think would be more fun particle physics or molecular biology? I love science and math and i love the idea of working on the most fundamental things of the universe, but i could do more practical things in molecular biology, so I am asking you guys what do you think?

I have 3 biology questions that I don't know the answer to...I have guesses on some of them, but I want to make sure of it before I hand in the questions to my teacher. I think 1 is B. For 2, I know that vascular cambia are found in gymnosperms and dicots. I'm not sure at all about 3...

We genetically modified E. Coli with jellyfish genes for flourescence. It was probably the coolest lab we've done yet. No freakin' titrations or counting and sexing any damn fruit flies.

The world has been working more and more over the years to research a way to live indefinitely with health. What ways can you think of that biology can make an indefinite life span for a human? Of course, I am not looking for a sure fire way, I am just looking for brainstorms and ideas.

In my biology class, I've learned that most of the fundamental processes of genetics occur on an atomic level (i.e. DNA, RNA, etc.). Can quantum mechanics be applied?

I am a 16 years old chinese, and i live in Missouri, US. Need some advice about my career, i love Physics. However i don't like biology, but i have to take it next year, or i don't get any other kind science class... It is a waste of time! I wish to quit school and start on my Physics work...
