Oh Linn...

Think of what resources dinosaurs and mammals needed, respectively. That should give you a good start.

It depends on the animal. In some species yes, and in others no.

And what exactly does your dentist mean about damage from continued use? You're only supposed to use white strips for a week (sometimes up to two) per year, does even that use lead to those damaging effects?

That's just the way it is. In every case I've heard of, cross species hybrids of animals don't produce normal/any reproductive cells (particularly in male hybrids), and thus cannot reproduce. It doesn't mean that there was some error in the genes that the parents passed on to the hybrid, the combina...

a. Sexual reproduction does not do this, so it can't be a b. Reflecting on the answer to a, what do you think about b? c. Thinking of the differences between sexual and asexual reproduction, do you think that this is a large factor? d. Look back at a to get a general idea about this one. I've given ...

I think that Google could help you find this very quickly, if the biology online tutorials don't have it. But just as a starter, enzymes help to speed up many reactions in an organism, with no additional energy cost. As for factors that influence their activity, enzymes are proteins, and if you thin...

Once the sperm cell and the egg cell have fused, the zygote begins to divide, and cells will eventually begin to differentiate. This differentiation eventually gives rise to blood, so I suppose that you could consider the blood to be created by the union of the sperm and the egg.

When I'm preoccupied with something, I find that I dream about it more often. It's not the same as choosing the topic for a dream in advance, but it's the only thing I can think of that suits your question. I can't tell you how many times I've had my mind on a girl, and then woken up in the middle o...

Perhaps your memory of Christian history is not quite as strong as your grasp of Egyptian history... The Christian Church (specifically, the Catholic Church) was hugely powerful in the past politically, and there were quite a number of popes who were... let's say very politcally minded, and maybe no...

Views: 3557

I don't think so, since I've known plenty of people who've done it without any side effects at all. My understanding is that you're just putting chemicals on your hair, and not actually into your body. So even if you did do something to your hair (like dry it out, or dye it a bad color), it'll still...
