I'm doing a bottled ecosystem project for biology and I have no clue how to start it. We are suppose to have the ecosystem last for 2 months. Should terrestrial go on top, so when the water evaporates the plants are watered? What organisms should I put in there that will last 2 months. What plants could give off a lot of oxygen to keep the organisms alive( its Fall). I live in Montana and I need organisms that I can get fast.

Anything is appreciated!!!!!!! Thanks

Consider the results of the following cross: RR x rr

(R is dominant and results in a wild type phenotype.)

The allele for wild type is said to be dominant, so why is it, for some alleles, the answer is not wild type? How can a defective allele present in one copy along with a wild type one, show the phenotype of a homozygous defective individual?

or something in between. My question is if we evolved, why is there not a simple form of us walking out of the sea every so often. Or all different forms of us in different stages of evolution. Evolution couldn't just stop at some point, as that makes no sense. This is where the theory of evolution hits the road. Isn't it??

Are all babies were born with 20/20 vision?
It seems like we watch too much tv, computers and spend too much time reading in the dark and our eyes get worse.?
But if you never watch tv, NEVER use a computer, and never read a book, then your eyesight will be perfect?

Starting with the elements on the Periodic Table, every molecule, water, and any source of energy that you need (wind, water, fire, solar, etc.) could you build a human being from scratch and then make him or her come alive? Or any other living organism? Money is no object either. I'll give you unlimited funds. Could you do it? It's not that hard to do. After all if evolution is true, dumb luck and blind chance made it happen. You're not stupider than dumb luck and blind chance are you? If you are, by your own admission, stupider than dumb luck and blind chance, then why would any thinking person take your theory seriously? Even if you have studied and learned a lot about science.
