  1. It's a direct result of the Ayran conquest. Still to this day the decendents of the Ayran invaders make up much of the elite in indian society, when the cast system was stronger it was even worse. A recent genetic analysis has confirmed this. http://www.dalitstan.org/holocaust/invasion/histgene.html This is especially true for women. Women with ligher skin found it much easier to upward in the cast system (even though this was still discouraged).
  2. I think far more harmful to the mind are certain social taboos that society beats into your head regrading porn than porn itself. For instance many will argue that extreem fetishes like violet porn, kiddie porn, and beastiality are a result of sex being portrayed as something sinful or negative. People are sexual creatures (for the most part) thus if someone both thinks sex is negative but yet can't help but crave it than it increases the chance that they will crave negative violent, dirogetory, etc. actions along with it. Basically by making sex "evil" you associate it with other "evil" actions. So for many when they crave sex they crave these other actions as well. Personally I don't see sex as nasty or rauchy or sinful or violent or attribute anything negative at all to it. So I have alot of trouble understanding how someone who does view it this way can find pleasure from such horrible things. Lol, oh yeah? And how much would you say is too much?
  3. Actually it's possible with virtually all plants. Just some need to be coaxed with some special care and rooting hormones.
  4. Okay here's mine. A bit of ms paint work. Hope you all can tell what it is lol
  5. Well nature is really more like a hybrid of the two. Only about 1/3-1/2 of it consits of peer-reviewed articles. The rest are mainly news articles and essays which I can't see most people having any trouble with. But I see your point, it's not very light reading. btw given my field of research most papers published with in nature are well within my range of full understanding. Most are biology or chemistry related. The only things that I don't really go into are the more mathy physics ones. But you only get a couple pages of those in most issues. I'm going to attempt to get back in touch with math and physics next time I have some real free time in my life.
  6. I don't know much about pitcher plants. But take many crawling vines for example. Many tropical ones just keep on sendiing out new roots along their length. the original part can die but it keeps on growing. The are even some speices of plants that are loosing the ability to produce viable seeds, they just grow from parts the fall off and grow new roots. actually I'm pretty sure that's the case with seedless oranges. Since the trees can't produce natural offspring they're propagated from cuttings. They're all clones really.
  7. I second that nature owns all those other mags. Though it is definatley more technical... You have to be pretty hardcore to read it. And costs about 5 times as much for the yearly subscription' date=' but it is weekly so you get almost 5 times the number of issues, and each is pretty thick. So it evens out, well if you're up for reading a full magazine everyweek. I let my subscription run out recently, my life has gotten far to busy for all the reading... sigh... But yeah if you're just interested in reading the daily news, nature is the place to get it. www.nature.com
  8. Ahh but you see there was energy put into that bond. The release of CO2 from alpha-ketoglutarate contains more energy than is required to form NADH. Metabolism is resourceful and funnels that energy into the addition of CoA so that it may then later be cleaved to transfer it to GTP. If there wasn't the addition of CoA after the decarboxylation there would be alot of energy wasted. Hope that helps. *edit* This ties into the most interesting part of the cycle (at least for me) The alpha-ketoglutarate dehydrogenase reaction is almost identical to the pyruvate dehydrogenase, so you could ask the same question about that. But the loss of the CoA from acetyl-CoA doesn't go into making GTP, it is used to pull the preceeding unfavorable malate dehydrogenase step that forms oxaloacetate forward. What you have to realize is that the whole thing is called a cycle for a reason. Just like how if you push on one part of a bikes wheel the rest turns so it works the same with the krebs cycle. The energetically favorable steps balance out the unfavorable steps and pull them forward. In the cell the free energy of the whole cycle is practically at 0!! just slighly negative allowing for it to proceed. Any additional energy put into one part drives the rest around. It's very efficient actually.
  9. I'd suggest putting a black outline around your hat Nevermore. You can't really see the white pompom agains this blue background to well. It kinda looks like someone stepped on your bug and it's bleeding from the head...
  10. Pretty much, but it might crack and fall over from it's own weight.
  11. The second is right, plants don't breath breathing involves the inhalation and exhalation of gases. Plants do respire however. The two words are not equivalent
  12. Is this a trick question? I'm pretty sure both will float lol.
  13. How does civil engineer apply differently to biotechnology than it would to other industries? Sorry I don't have an answer to your question. But I can't imagine what civil engineerin in biotechnology is.
  14. Why do you want to get rid of this rock anyways? Most people pay good cash for large rocks in their yards.
  15. Seems I was right. "Sometimes eating or drinking too fast can make a person burp because this can send extra air into the stomach. The same thing happens when you drink through a straw: extra air in = more burps out." http://kidshealth.org/kid/talk/yucky/burp.html I know it's not very authoritative source, but the probability of the first source I find agreeing with my random prediction is pretty low unless it's not a coincidence.
  16. I think I know the answer. It probably has alot more to do with the the mechanincs of how one drinks with a straw than it has to do with presure or chemistry. (and I'm a chemist so this definatley is a stretch for me) Here's my theory: You see when you drink with a straw you will be swallowing smaller gulps than if you drink straight out of the can. This means that you will have to swallow far more to drink the same amount. By swallowing more you're increasing the total amount of air that you end up swallowing for drinking the same volume of liquid. Also you need to consider the "void" volume of the straw, there is air in the straw before it fills with liquid. So this air is also sucked out and swallow. So you see the extra burps you're getting from drinking from a straw is due to extra swallowed air and not extra CO2. Every notice how if you drink juice out of a juice box it makes you burp as well? I remember getting lots of burps from apple juice when drinking from a juice box. You see what your current experiment lacks is a set of controls to eliminate possible variables. Set a bunch of these up and you can probably prove one responsible for the effect. Try the experiment with a non-carbonated beverage. (you may have to drink alot more) I bet you'll get more burps when you drink it with a straw as well.
  17. To be more specific it causes the depolimerization of microtubles. (mitotic spindels being microtubles.)
  18. Lol being the overanalytic sob I am. I've just noticed that the homework forum has the lowest post/thread ratio of any forum!!!! at just below 6 posts per thread. The average being just above 10. Which has two possible explainations both of which make it undesirable to have homework posts in other forums. Either the questions don't incite as good discussion, or people just don't want to do the homework of others.
  19. I'm pretty sure the rule is to not post in the wrong forum. ie ask homework questions outside of the homework forum. I think the problem lies in that if it is the wrong subject forum than it's easy to identify it as the wrong forum. However the difference between a question based on interest and homework might not be as obvious. (Not that it wasn't clearly obvious in this case...) It's hard to tell if the reason so many of these question appear outside of the homework forum is because the authors are ignorant about the existance of a homework forum or if they do it purposefully since other forums get alot more activity. *edit* like if you take a look this forum has less threads than the homework one but it has more posts!!! Implying that if you ask a question about homework in the wrong forum you're more likely to get a response.
  20. There isn't one?? Well if there is it doesn't appear to be enforced...
  21. Hey thanks Skye that's interesting that you said that. I acutally proposed using heat to melt the DNA and then seperating it to a PHD student in my lab and he looked at me like I was crazy. Though my idea was to pass it hot through a column. It is possible but tricky. Percipitation might be easier, but it may also be tricky getting the right concentration of salts as solubility will change with temp. But we both can't be crazy right? lol I'll definaltey try that. It looks like I have a few things I can try. I'll give them a shot tomorrow probably (assuming I have the supplies in lab now) and tell you guys about the results.
