I don't know yet. He never gave us anything back. But, I assume I did well.

I ended up talking about the myth that humans only use 10% of the brain.

Could you be more specific?

I have to write a paper for my physical science class on pseudoscience and I was hoping that I could get help finding a great example of pseudoscience being exploited in today's society.

Plant Sciences, Zoology & Evolution / Telemerase

But that is not the case in sex cells is it? If it were the same in the sex cells, then surely all animal lifeforms would be dead by now.

Plant Sciences, Zoology & Evolution / Telemerase

« on: 25/11/2008 15:40:21 »

So basically this stuff is the life-line?.?.?.

Is it possible to live without telemerase in the chromosomes? If so, are there any creatures evolving away from it?

I am not exactly sure on how it functions in the genes but to the best of my knowlege, it is used in the reproduction of chromosomes. Correct me where I am wrong.

but isnt hydrogen much more explosive than helium?

Well how much air would I have to displace to allow me to lift?

Alright thanks guys. I appreciate the answers.

Then would that indicate that the platypus is one of the oldest mammals?

Question of the Week / Re: QotW - 08.11.16 - Are we the only animals to cook our food?

« on: 20/11/2008 16:08:30 »

I believe we are the only animals to cook our food, but I have heard of some primates washing their food.

We cook our food to kill off germs, and because I would really not enjoy a raw steak.

WE are not, however, the only creatures to colonize (for lack of a better word) other creatures; some breeds of ants will enslave and raise other ants and even other insects. They are used as slaves to gather food and even raised for consumption.

Does that count towards a darwin award?
http://en.wikipedia.org/wiki/Darwin_Awards

NO. I don't think I'm worthy of the Darwin Award. But thank you for the nomination. But let me ask a more personal question. I weigh about 205 lbs. How big would the balloon have to be to lift me about 15 feet off the ground?

Plant Sciences, Zoology & Evolution / Could evolution represent the merging of multiple species?

« on: 19/11/2008 17:51:05 »

As far as I know about evolution, it seems to be a pretty sequential process. That is to say that it starts in one spot and divulges from that origin. But here is an idea that I have in my skull--what if it also worked backwards? Could it be possible that a species (maybe not necessarily the humans, but a species) is the culmination of other lifeforms evolving into one single species?

Chemistry / What happens if you take away all of the electrons from an atom?

Not the same as the stuff in your blood though!

I am very glad that is not in my blood.

Technology / How do water fuel cells work?

« on: 18/11/2008 21:00:26 »

Here is an idea...

Use dam power or solar power, or some other form of natural energy to produce an amount of fuel from water. Then use that as starting fuel to operate a motor, that will send more electricity into a hydrolisis.

Maybe the thing to do is not to try to seperate the molecules within the cars, but rather to put them in the car like we do with gasoline.

Critique please.

Physics, Astronomy & Cosmology / Polar shifts due to the famed planet Nibiru

« on: 18/11/2008 20:41:32 »

Well what would be the outcome of a polar shift?

And how would planet X entering our inner-solar system cause that?

Technology / Re: What electronic device is required to light a series of bulbs in sequence?

« on: 18/11/2008 20:38:08 »

Would I be able to use a similar device to power electro-magnets, in sequential order? I want to have 4 electo-magnets aranged in a circular pattern on a board. And I want a wheel in the center, with a peice of iron. So eventually, I am trying to build a motor. This may be inefficient, but it is for my little sister's science fair.

Technology / What electronic device is required to light a series of bulbs in sequence?

« on: 17/11/2008 23:39:30 »

I need an electronic device to create a pulse. I will provide a source of electricity and I need something to make it pulsate in a sequence. For example, 4 lightbulbs that shine in sequential order. But one can not shine until the other has died out. I want to arrange the machine in a circle pattern, with 4 points. Can someone please give me some ideas? Thanks.

Technology / Could a microwave be used to heat a home?

« on: 17/11/2008 23:28:10 »

If microwaves are so energy ineficient, why not just cook with electric devices?
