I really suck at biology and the textbook doesn't really give me the understanding of the answers. Is there a safe site that I can look things up in biology? I'm currently working on plant structure and function, leaves and flowers.
Thankyou for your answers in advance!

I'm curious as to why, when you hang upside down, why does the blood rush to your head, yet it doesn't rush to your feet when you stand up? Nobody I know can answer this question; we're all stumped.

claming to be athist is the best way to not be accountable for your actions.

but the law states that you cant get energy out of nothing and the hole action/reaction laws also are not related to athistism.

what do you think?

The first law of thermodynamics seems to conflict with what we know about ourselves. For example, after strenuous exercise we run out of "energy". We must eat to replenish our energystores. Where has that energy gone? Where has that energy gone? What form has it taken?

Even down to a tiny protist swimming in pond water, we are all in water somewhat. There is water vapor in the air. However, I would like a more elaborate answer for this question. "all life is aquatic" is a genaric phrase, and I cant decipher it.

The question I asked.

Now I have questions for the people that answered...

Do you know how to read?
Comprehend words?

Half evolved fossil! I know were fossils are. I have been to research facilities and seen them. As I am sure many people have.

I said HALF EVOLVED FOSSILS! Do you need me to type that again?
Have you ever seen a fossil of a fish...becoming a bird?
With distorted bones and unspeakable changes to show it was actually changing from one animal to another?

THAT is what I was asking.

I have read Darwins theory and I am just wondering why people are treating some old mans thoughts and opinions like a fact.

I do not treat the bible as fact, so dont try and throw that at me.

I know why the Electron Transport Chain stops due to the lack of O2, but why does the Kreb Cycle stop as well?

I thought Kreb Cycle didn't require oxygen directly to function?

Probably it is the lack of water, since human can last a few days without food but aproximately two without water, but what exactly? I was wondering what is the exact reason of death. All biologists are very welcome to answer talking biological.

I watched this movie about these dudes that didn't make it through the desert, what a gruesome death. It got me wondering.

Ok creo's and evo's we all know about poluxy and we know what it shows giant man and dino tracks

creos claim it wasa giant man as the atmosphere would support giant lizards, beavers, rhinos which have all been found, so any men around would have been giants too


but lets not babble.

Why do evolutionists simply test this rock and some of the footprints and give us a date?

Why do they never test creo evidence

Just radiodate using some of your methods and tell us what you get

there must be evo scientists with dating techniques in their labs from america repsonding to this question

so why not test the footprints and give us a date for them

that would **** up one group of people

does anyone know why these footprints have not been tested

will someone please test those footprints, using any method you like

at the same time can you also test the mayan claypots, which show the mayans riding on the backs of dinosaurs too
thanks

lets test these things and get an answer for everybody

Since they do not use mitochondria and the electron transport chain to harvest ATP, but rather obtain it from photosynthesis
