Development tends to, generally, refer to the growth of a single organism throughout its life. Evolution, on the other hand, usually refers to the growth and change of an entire species.
This question seems to rest mainly in the definition of mathematics. If we say that mathematics is a language to describe reality, then I think it makes it all much clearer. For example, we see pairs of things in nature, so we give it the term "two" and begin to form the idea of "two" separate...
I'm wondering if, when put into the DNA together, two different restriction enzymes will interfere with each other, and how. Will two different restriction enzymes cut the DNA as they each would separately, since they are specifically formed to react with it and not each other, or would they...
I'm not sure if I understand your question, but it may help that pheremones, at least in humans, are not recognized in our daily lives. Male glands secrete androstenol-- what they believe is a pheremone-- that repels other males and attracks females. The below link doesn't mention this, but it...
And, in agreement with gravenworld above, I suggest looking into "Godel Numbers," a system that translates statements into mathematics. There's a fantastic and relatively comprehensible book, Godel's Proof, that walks you through the Godel's process of constructing a proof, from a...
ShawnD, that answered my question exactly. I wasn't sure how the notation worked, as far as just throwing the correct number of H+ and so forth.
Thanks. :wink:
I'm not sure how to balance this equation with regards to the half reaction and electrons, as well as the elements:
Fe+2 + Cr2O-27--->Fe+3 + Cr+3
Right now, I've gotten this far, though I don't know if it's the right track:
Fe+2 + 2Cr+72O-27--->Fe+3 + 4Cr+3 + 7O-22
What should I do next?
