Question: I was assigned to do any topic involving chemistry. I chose to do an essay on the Black Widow Spider. I don't know what to write about. Should I write about it's habitat, reproduction, and evolution?

You just said it. What I would do. Research the three things you mentioned. Have an Introduction paragraph that lead into those subjects. Then depending on how long this need to be you have one paragraph explaining the three subjects of interest and then end with a Conclusion. That be 5 paragraphs total. If, it need to be something like a 10 page Essay. The one page for intro, eight pages for your subject and one page for conclusion. Just divide everything up according to how long the Essay need to be. Good Luck, this sounds like a cool subject. Below me may be better advice as he explains. I been writing essay and research papers for so long I get over excited. Heck, I almost can write an intro and conclusion for any subject just from experience of doing this with no knowledge of the subject. LOL! Remember the first rule of school. "If you can not dazzle them with your intelligence, baffle them with your bull sh*t"!

Boy you've got your work cut out for you here. First, black widow venom is not one molecule. It is made up of several different molecules that all interact together to bring out this toxic effect. However, there is one subgroup of molecules, if you will, that are the key ingredient to the venom. They are known as the latrotoxins, which there are seven of, five of which are present in black widow venom. For the sake of the question I am going to assume you are considering the alpha-latrotoxin which is what works on human beings, which is also the most studied. Now for the part that's going to ruin your project for you. There is no known structure. That's it. I said it, and now you hate me for it. According to all medical journals that I could find, scientists just recently obtained a 3D image of the alpha-latrotoxins. For the good news: how it works. The alpha-latroxin molecule sort of binds to the cellular membrane and forces Calcium molecules across it, which trigger neurotransmitters to be released. This influx of neurotransmitters is what causes all problems associated with the venom. Hope this has helped you a bit, and I would seriously consider having a talk with your (chem?) instructor if they chose this for you. If you chose it yourself, you might seriously reconsider what you're doing your project on. This would be a massively difficult paper for a graduate student to write, and I assume you aren't a grad student as you haven't already done this background research. Good luck!!

This is a very good question! It's not quite that simple, though - most venoms are made up of a mixture of various proteins, and widow venom is no exception. However, I suspect that your instructor is interested in the primary protein component of widow venom, called "alpha-Latrotoxin" (Widows are members of the spider genus Latrodectus, so that's the reason for the name of the protein). The effect of this protein, in simple terms, is to bind to signalling sites in nerves and release all the molecules that the nerve uses to send a signal to the next nerve to fire off an impulse. This causes the receiving nerves to basically send an overload continuous signal out, which will end up causing muscles to lock up instead of contracting and relaxing. These neurotoxins essentially paralyze the spider's arthropod prey in a very short span of time, and at least this one has a very potent effect on mammals as well. I've linked you a wiki and a couple of interesting papers - the first two papers cover the basic information, and have most of the info you need, but don't give you the 3-d structure of the protein. The last paper (and especially the third link, which goes to an excellent and well-illustrated summary of that paper) give you the structural information you want to know. You'll need to have a computer that reads .pdf files (Adobe reader, as up-to-date as possible). This is a fine project, and I hope you do very well on it!

You might want to go to a library to research the effect the spider's venom has on the various systems of the spider's victims! This would be in the purview of Chemistry. Habitat, reproduction and evolution are far removed from that subject area!

Evolution impacts issues in such particularly some techniques and there are various aspects. the element is that evolution isn't ideal. no longer something is. we choose evolution by skill of our very own standards. some blind creatures with eyes as an occasion could hit upon a various spectrum of light that's no longer seen to us including infra purple. Sacrificing ones self isn't something to do with evolution it is an envronmental ingredient. people wouldnt sacrifice themselves if that they had no reason. Ie faith is a man made philosophy progressed till now actual technological awareness emerged. sacrifices have been believed to soothe the gods. this could be a made from faulty mind no longer evolution.

Laurel Originally Answered: How do you feel about the 79.5 million awarded to widow of long time smoker?
Is there anyone who really believe that smoking doesn't cause cancer? The Surgeon Generals didn't FORCE the cigarette manufactures of put the warning on for no reason.. How could he not see the paperwork? It was on EVERY pack he bought. It's been in the NEWS for decades. There were songs about it. Next how do we know what he believed? We can't question him now, why didn't HE file the case when he got cancer? Had he started that action and gave a deposition then we would know what he said. Instead we have his widow claim that he didn't believe the warnings. If I was on that jury she wouldn't have got a dime. But, wait a minuet I remember a study that proved vitamin, C, and E causes cancer in rats. Maybe I should sue Minute Maid. Yes that's it I want my Millions right Now. If you smoke don't be surprised when you get cancer and don't expect me to feel sorry for you.
