Just use the scientific method. Buy a few other trees that are the same species of yours. Plant one outside and compare that one to others that are undergoing varying amounts of light/day (and whatever else you want to test to see if it goes faster or slower.) Measure each tree every few...

I have a pet cockatiel (which I love to death!) When I first got the bird, I wondered why as well. But as the others have said, it helps with a few things. It provides them with a warm, safe, and dark sleeping environment. Most birds need at least 12 hours of sleep, and humans only sleep for...

Another consideration is the speed of light. If any gravitational anomaly occurred from the alignment (which I seriously doubt it would,) it would take millions of years for the effects to be felt on earth. Don't forget about the speed of light, which applies to gravitational waves that propagate.

Well it pretty much is for hobby purposes, but a good hobby microscope that I may be able to do some research or observations with. I would like to be able to get a good glimpse of blood cells, pond water organisms, mold, algae, and yeasts. One thing I was wanting it for is to view yeasts...

I was wondering if someone would recommend me a good microscope? I am majoring in Molecular Biology, and would like a decent optical microscope for viewing cells and bacteria. What is a good and reliable model that is not too expensive? I see a lot of microscopes on ebay for around $250-$350...

Ok here is another question, a bit off topic. I know that sec(180 = -1. But this is the question I have. -When looking at 180° in standard position, we realize that y is 0 and x is any given number along the x axis. -sec is understood to be r/x. - So let's say I choose (5,0) -I need to...

Ok let me try this again: The attempt at a solution sec(180 is -1. So we have 4(-1) which is -4 sin2(270 is (-1)2 which is 1 So we have 2(1) This now reads -4 - 2 Answer = -6 Is this right?

Positive?

Homework Statement 4sec180° - 2sin2270° The Attempt at a Solution sec(180 is -1. So we have 4(-1) which is -4 sin2(270 is -1 So we have 2(-1) This now reads -4 - -2 Answer = -2 Is this correct or do I suck at this? =(

Sorry if I repeat anyone, for I didn't read all the responses. Sleep isn't a survival skill with respects to dodging predators. We need sleep for replenishing energy and resting our muscles. Every animal needs this, in some way, shape or form. Insects do this, but they are only brief second...

Well obviously I could log onto my ebay account and throw them on there and in less than a week they will all be sold. Yet I am not the kind of person who chooses convienence over self dedication. I would rather learn the ropes, and do everything myself, than ebay getting a cut out of these...

Not to mention Even if you ate all healthy foods, but more than you needed and got big.. you're putting an extreme load on your heart. I'm not talking about just clots and whatnot. I'm talking about a larger body that makes the heart struggle more to deliver the blood to all the right places.

Please then explain how some animals can fight certain infections and diseases while others cannot? If your statement of "You are not born with antibodies; you have the ability to make them, but their form is not determined until an actual pathogen is introduced" is completely true, then why are...

It depends how the civilization is in the hypothetical "future" that I stated. It would depend on how the humans would store information and if that information was erased, it would be disastorous. Also, evolution does somewhat have a "direction." It adapts nearly all aspects of any given...

"The Main Human Adaptive Strategy: cultural evolution. We are getting better at many things collectively, like the medical assistances you mention." I disagree here. Evolution has shown us if you need something for survival, evolution will try it's best to provide it. (Sonars for blind bats...
