Biology - October 2007

Just finished my Biology project, and now we have another! Yay.

So here is what I know, which isn't much and quite possibly wrong:

AMP =First
ADP =Second
ATP =Third (Triphosphate?)

I also know that they store energy.. but I know nothing about that. So how does the cell use this energy, and what exactly is it? Also how do you go from say a ADP to an ATP.. Or an ATP to a ADP (is going from 3 to 2 even possible)?

The section in the book was very confusing. So please.. explain to me the wonders of ATP and what their role is in a cell. I don't need to go very in depth, just generally what they do and how they are useful to the cell.

And please don't use big scientific words. They make life bad.

Edit: The teacher mentioned something about this in a past class. He said that cells want to have energy stored so the cell can use it when it needs it and not just use it all at once and not have anything after. Is that a reason why it's useful? W/e, explain please!

For an enteric bacterium, would it be possible to track the movements of the bacterium within the living host, without detrimental effects to the host?

This has been done with mice and Salmonella before: does anyone have a reference for this?

Could you label the bacteria with something that could be tracked through the host?

I read an article in Wired magazine the other day which advocated scientists start referring to evolution as a law rather than a theory.

The idea was that theists and supporters of intelligent design have seized on the phrase "theory of evolution" to indicate that scientists are not confident in the idea. They use a layman's definition of theory which mean something you think but can't really prove. However, when a scientist uses the word theory, they often mean something that would be more equivalent to the layman's definition of law.

For an assignment, I haven't gotten around to asking people.

Which of the following statements do you think is most correct, regarding evolution?
• Evolution is the greatest myth of the 20th century. It has no really hard evidence to support it
• Evolution is a fact. Everyone knows that humans evolved from apes.
• Evolution is all about adapting. When the environment changes a species will adapt and evolve to cope with their changed surroundings.
• Evolution is descent with modification via the process of natural selection.
• Evolution is organisms changing themselves to perfection

Thanks all

I've heard of white muscles, where the muscles are strong but lack stamina. I've heard of red muscles, where muscles have stamina but lack strength. I've heard of red (type b) muscles, where its in between but have moderate stamina and strength But, are there pink muscles, where it contains stamina of red muscles and strength of white muscles combines? If so, how do you train it to become that way? Any routine (even for red [type b[ muscles)?

If we emerged from a pool of primordial ooze after being struck by lightening and created by mere chance. What chance is it that we are on this Earth for a purpose. We live, we die, we become extinct. For no purpose unless we evolve into a higher life form which seems unlikely. It seems we have stretched eveloution to our limit. It is more likely the cockroach will take over from here. How many say we can take it one more notch and how many are for the cockroach?
