hey guys, i am trying to find a easy method to extract nicotine from tobacco at home. guys, before we start, i would like to tell you that this is not my first time and i have already did it with many other methods including the apple osmosis one which i found the cleanest and easiest. so i know how dangerous is it, and if i want to commit suicide, i will just put couple of drops of disolved nicotine in alcohol on my skin. so okay, my aim:- find the most easiest and cleanest method of extraction of nicotine from tobacco at home. which also means that i am not going to use any fancy chemicals or apparatus for this process. and this is active discussion for de…

I have been getting incredibly interested in the universe and how it works lately, including astrophysics, biology, and where everything comes from. I've come to learn that many of the materials that make up the Human body, such as calcium and iron, can only be formed during nuclear fusion in stars. All those materials then get scattered throughout the universe when these stars explode, which is how they eventually came to form the Human body. So, in essence, all of us originate from the super nova explosions of stars. Now my question is what happens when different animals on Earth, including Humans, mate? That baby now has calcium in his bones and iron in his blood. …

While his clouded eyes Strahlend sees nothing, in museums around theworld suddenly, for nowhere to start mark the beginning of human evolution 200million years ago. While in these museums is really nothing to compare this with my facts,no. A lie in these museums are the same previously found the remains ofwhether the monkey, or similar to her man, not yet had time to turn to stone,as their antiquity were calculated only tens of thousands of years. It turns out that professionals working in the field of anthropology,paleontology and archeology have been far-sighted than you Strahlend! Whenthese professionals looked at my documentary photos on the Internet, the…

This is my first post here. Please read it and comment with some feedback. Thank You. This is a review on the documentary The 11th Hour. The documentary The 11th Hour offers ideas, facts andarguments concerning the need for man to live in harmony with the planet Earthas well as solutions to solve an ecological and social crisis. Presented by Leonardo DiCaprio and dozens of guests such as M. Gorbachev and S. Hawking. Followingthe perspectives presented by several speakers from the movie 11th Hour, theman is living in an unsustainable way, given that we are part of a much largersystem, Nature, or Earth. This means that man isrecklessly expanding the company…

I am interested in Owners of tobacco and I'm trying to get the taste of tobacco upand download from the point someone could help me how I can do it? What can Idip the leaves to come out of them taste when smoking them Hope you can help me Thank you

Firstly, I am new to the forums, and I'd like to say hi to everyone. I hope this big enough forum will be able to better educate me with intelligent critiques/opinions/debates. Sorry but I made two posts, one in Biology, and the other in Genetics. If someone could help me delete the post in genetics, I'd appreciate it! While I was in the midst of talking with my colleagues, I mentioned about cryonics, which later shifted to a discussion about a researcher named Aubrey de Grey... The moment I mentioned his name, a numerous amount of reactions encompassed me. As numerous as they were, all of them had the same affiliation of animosity. Heretic, fraud, naive, etc. I heard…

My SDS separating gel contains Tris/SDS and im trying to calculate the conc of this in the gel.... The tris/sds stock solution was made initially from: 6.05 g Tris 20ml of 20% SDS 80 ml water to give a total volume of 100ml. So Tris/SDS was made in this solution. I want to calculate to concentration of Tris/SDS in this solution, so do i have to calculate the tris and SDS concs seperatly or together,,,if you get what i mean. I hope this is clear, any help will be much obliged

In the haploid male ant, I assume these must occur in preparation for mating: (1) Germ cells do not start meiosis. (2) Germ cells are converted to sperm cells. Are these assumptions correct? Obviously something works; I'm curious about the details. Regarding (1), meiosis generally works only with diploid germ cells, correct? Whereas the gene works OK with female ants, is it turned off for males? Or does the gene interrogate the germ cells? Such interrogation would be wasted on 99% of the germ cells. Regarding (2), the final part of spermatogenesis, following meiosis: "Spermatids mature further in a developmental process called spermiogenesis, becomin…

Hello everyone, I'm learning Malaria right now, and thought it would be good for me to differentiate plasmodium vivax and plasmodium falciparum. P.V Produces benign tertian malaria, Some sporozoites remain as hypnozoites, Merozoites enter new RBCS Ring stage, amoeboid, shizont, gametocyte can be identified using microscope P.F Produces malignant tertian malaria, Cause more severe infection No hynozoites, Merozoites enter RBC of all ages Only ring stage and gametocyte can be identifed using microscope Now my questions are, 1. What is the difference between malignant and benign malaria? Malignant one obviously sounds bad but what is the exact di…

hello could you help me please ? how can we save water and what do you think of re-using water of bathing water in the flush instead of clean water ? SARAA

Hi could anyone please supply a step by step numerical breakdown of the processes involved in DNA replication? I mean I know some processes happen at the same time, but what's the general thrust of things? It would be really helpful if I could see something in a step 1, step 2, step 3 step 4 etc. type format. You see the problem is I've read about and watched loads of videos about each of the individual steps, but I'm having real trouble stitching it all together. Of particular confusion is in this video here: it shows the DNA molecule being copied into RNA first, presumably for later transcription back into DNA? However in this (really very good) online tut…

How do you explain this mysterious phenomenon? An Indian yogi says that he survived 70 years without eating. http://bodyodd.msnbc.msn.com/_news/2010/05/10/4380027-70-years-without-eating-starving-yogi-says-its-true http://www.telegraph.co.uk/news/worldnews/asia/india/7645857/Man-claims-to-have-had-no-food-or-drink-for-70-years.html This phenomenon cannot be natural or can it?

Hi there I'd like to tell you about a new online tool thatwill help researchers design and build their perfect cutaneous or corneal Primary cell protocol. The idea behind the tool was to try to remove much of the trial and error (not to mention time and cost!) associated with developing a new primary cell protocol. The tool is packed with interactive features andinformation that allows you to confidently specify your perfect Protocol. The interactive protocol tool is completely free to use - no matter how many protocols youbuild. You can easily build your protocol in 5 minutes or take your time to investigate the different media types. If you would like to try bui…

Within the past couple of years genetic researchers claimed that cats can not taste sugar because they lack the gene, common to most/all mammals, that allows them to sense sweetness. I have a basic objection to this, along the lines of a 'so what'?: Parallel evolution. A cat may have lost that 'standard' gene that allows sugar tasting and replaced it with another, with perhaps somewhat different mechanical operations. Especially the selectively bred little mutants we call house cats. Much like the claim 'cats don't eat carbohydrates", another objection I have is the experience of myself and thousands of others: many cats will, without prompting, steal and devour f…

how can one measure total magnesium content and total atp content in muscle biopsy. thanks

So far I've tried eating smaller portions than normal, but it's still really hard for me to not have stuff with a lot of sugar (like soda or cookies). This might come off as a crazy idea, but would I be able to reduce my normal appetite by looking up as many disgusting pictures or videos as possible? Or would it just make me queasy all the time?

Hello everyone, Bacteriocidal- Example quinolones who inhibit DNA synthesis Bacteriostatic- like aminoglycosides which inhibit protein synthesis Now my question is bacteriocidal means bacteria must be killed, now if DNA synthesis is inhibited, the bacteria won't be able to replicate and create proteins. Ok the lack of protein would kill the bacteria. Now bacteriostatic means prevention of bacterial growth. How can inhibiting protein synthesis not kill the bacteria, and how does it prevent bacterial replication. Also what category does beta lactamases which inhibit cell wall syntheis fall into. Thanks

well im waiting for your questions. i dont have all day you know

How does species divergence occur in the process of normal evolution if both a male and female are required to perpetuate a new species? Isn't the odds of them both occuring spontaneously, at the same time, almost nil, aside from a twin pairing? I am not suggesting any other explanation, but I am curious what is to be said about this.

Why do some people seem to be very tolerant to pain? In the news I often hear that some people commit very painful suicides. Are these people actually NOT afraid of painful death and if so what makes them so special that they don't actually feel much pain?

I'm stumped at this question, I can only think that the question is answering itself ? Question: Cancerous tissue is composed of cells undergoing uncontrolled, rapid cell division. How could you develop a procedure to identify cancerous tissue by counting the number of cells undergoing mitosis?

hello guys! Biologist often use agar to plant things, and I would like to know how to make agar...... Thanks for any help in advance.

My question is simple. WHY??? What "force" causes the proteins to bind? Why does A bind to C? Why does G bind to T? How did DNA know to do this? Why does the random chaining of DNA inside the nucleus of a cell lead to the development of an extraordinarily complex organism? HOW does DNA know to allow its instructions to be read, replicate itself, and if need be repair itself? These are not things we would think happen naturally in our world. Compare it to building a skyscraper. Ive never seen them build themselves. It takes the hands and minds of thousands of workers and builders to collaborate. None of this makes sense to me. Without DNA we simply woul…

Hi, I would like to ask for your humble cooperation, if possible. The topic for my project is "Analysis of Sleeping Habits and Patterns for different age groups". Hence, as a part of my Biology Project, I need to conduct a survey. The link for the survey is : http://www.surveymonkey.com/s/W3R5KGQ No personal data is collected. Your Name, though optional would NOT be a part of the statistical report. I shall post the results as soon as I get the replies. I do not want to make fake reports or just state my source as secondary so this is a perfect medium for this task. Thank you once again for your help.
