i dont understand the meaning of "In telophase II, the nuclear envelope reappears at each pole and cytokinesis occurs. The end result of meiosis is four haploid cells each cell contains half the number of chromosomes, and each chromosome consists of only one chromatid. Later in interphase, a second chromatid in each chromosome is replicated, but the cell will still have only half the number of chromosomes."

I dont understand how each cell contain half the number of chromosomes and I dont understand four haploid cells, why not 4 diploid cells? what makes it diploid?. For some reason I understand Mitosis 100% but meiosis get me stuck only at telophase II. Can you help me?

In Evolutionary theory, I am assuming similarity does not necessarily imply relationship. That would be to retarded to be believed by intelligent humans. Obviously a bat is not considered a transition species between birds and mammals. SO how in fossils do they know what is a transition species and what just acquired similar traits then dead ended. I'm thinking about archeopteryx in particular. How is it known it was an acestor to birds and not just a reptile that developed bird like flight, then dead ended, and birds came from another source.

Please no answers defending evolution. YOu are wasting your time, because I'm not attacking it. Just explain the answers nicely with terms someone with little science background can understand.

I think these things in the shower after talking with friends who are knowers, I have never attended secular education beyond English classes and math, so too many terms will lose me.

Why are they all called dinosaurs? I mean it looks to me like there is no moare a relationship between a triceritops and a dynoninchus then thate is between a hippo and a chicken. And how do we know they were all reptiles? Couldn't triceritops be a mammal. He looks like a rhino.

I know that it involves the body seeing itself, in a way. I know that there are three constituents to the sense of having a body which is one's own: vision, balance organs (vestibular system), and proprioception. I am just trying to put this whole concept together...

FDA decides that there is no need for labels to distinguish between animals that are natural and those that have been cloned.

Are you comfortable with that?

Im not!

But they are not asking for our approval or permission so I suppose there is not much we can do about it?

Not to mention they have been doing it (feeding it to us for testing) for over 5 years!

Scary days here in America huh?

I can see the toy speak and spell problems now...

What does a cloned cow say children? OOOOOMm, OOOmmmm... BRAINS!

Disclaimer on the label... There is no difference between real cows and cloned cows the FDA says so.

I want to know if human beings are supposed to be vegetarian, and that through evolution have evolved to eat meat- like how we developed the need to consume salt.

Or at least, I'd like proof that humans are supposed to eat a diet consisting mainly plants and vegetables.

Please have scientific evidence to back up your explanation (ex. it is the reason teeth are mostly flat)

Thank you!
