  1. YT2095: Yea if it were to react with plastic then we'd have problems storing it jdurg: So its shock sensative at high concentrations - thats not good :S I added a piece of liver to low concentrated Hydrogen peroxide once and the whole test tube was filled with Oxygen bubbles in seconds. At high concentrations I'd dare not try it... Cheers, Ryan jones
  2. Ok, thanks jdurg Cheers, Ryan Jones
  3. Oh... its one of those I'll just have to work extra hard to make shure I get it right then I have one more question what do the f and g orbitals look like? Cheers, Ryan Jones
  4. Should that be right? I mean it can explode though that is with contamination - it on its own does not explode. Can just about anything cause the Hydrogen Peroxide to decompose? Cheers, Ryan Jones
  5. It was the chloroplast ad plants were actually the first things to form, thus the reason we are here. there were these little tiny plants called algea that took Carbon Dioxide form the air, produced Oxygen as a result although the Oxygen was toxic to these and the buildup eventually caused them to be wiped out but there we go Oh and this was actually the start when those heavy Iron(III) Oxide deposits were formed. All that Iron in the ocean was oxiudused by the now dissolved oxygen forming rust, Iron(III) Oxide and thus accounting for theose lovley red rocks we find! This is the first case of anyhting affecting the climate on a global scane and it allowed us to evolve! Well... they were not plants as such but were photosynthesising algea Also, if you look at bacteria you'll find they are prokaryotes - they do not have organells but algea do. If you olook at bacteria you'll find they still don't have mitocondria... (Reference here ) Cheers, Ryan Jones
  6. I was reading an article on how they plan to detect the grvitons using the [acr=Large Hardon Collider]LHC[/acr] when its built along with a load of other interesting things @JonM: - That is sort of what a black hole is considered to be. Its a hole in space time - I'd just like to know how string theory would explain this. Seeing as string and M-Theory are still in their early stages of development compared to some theories then I may have to wait a while to get my answer to this one as a lot of it is yet to be fully understood Cheers, Ryan Jones
  7. Yea definatly. Worst thing is that most people that protest this stuff don't know what its like to have a child or someone close to them with ain incurable genetic dissease, I don't either and I hope I never do. Most of these people also don't even know that cloning an genetic engineering actually are all about (I'm not shure I do either mind you ) - education is the first step to acceptance in this case I think Cheers, Ryan Jones
  8. Good questions - I live them I'll do my best to answer these. If you think of it this way - space and time are one and the same according to GR and SR, therefor as long as space exists so too does time - did space exist at the point of the big bang I'm not sure but if it did then so too did time. Time is relative, my time if a mixture of your time from yuor reference frame and everyone elses too... its also affected by gravity Time in black holes - an interesting one. Because a black hole can be conidered a gole in space with spacetime being destroyed at the singularity you could say that time moves towards the singuarity and ends as you hit the singularity as itand space time and everything else are destroyed Was time the same as it is now during the first miliseconds of the big bang? I have no idea - if space was there then time must have been also. All that mass in one space though can make things quite confusing Maybe someone can answer these better than I? Cheers, Ryan Jones

    Correct Remember for this to be a fair test then you must only change one variable at a time and keep everything else as close too ideantical as possible You shuld probably make a prediciton for each experiment too - I cna help you with that if you like (I got full marks for this part.) Also, do not be afraid of errors (Just keep them to a minimal) - errors will help you to show you've thought about the errors and that if you did the experiment again you'd know wheere you went wrong. I know this is hard to believe but if you got the experiment perfect with no errors then you'd get less marks than if you had one with a few errors. The reason being you had to explain the errors and work out how you could fix them. You don't have to do this but I did and it took the longest part of my time This experiment has so many different ways and things to try thats why I always use this. I've tried different types of acid, different strengths, same with bases. I tried a combination of heat and acid later after I finished everything else... Like I said the list is all but endless. You could even try using different foods and comparing the speeds of those! I had a great time doing this experiment and I hope you will too Cheers, Ryan Jones
  10. If its possible at the current rate of technological development I'd say within the next 50-100 years (Maybe to about 200) So maybe within my life time Cheers, Ryan Jones

    In most cases preassure ipnot one you'll be able to do as the apparatus are quite hard to get hold off When I did this experiemnt I did it with catalase and diliuted Hydrogen Peroxide. The catalase enzyme was from pieces of potato (equaly and accurraly cut) and I then measured out a set ammount of Hydrogen Peroxide and did what needed to be done to the enzyme (E.g. heated the potato slice) and then added it to the Hydrogen Peroxide and measured how long it took for the reaction to finish (the bubbles to stop comming). Warning: Be very careful with Hydrogen Peroxide - it can be nasty stuff to get on your skin so wear gloves As for other enzymes I'll leave you to do some research on that part - there are literally thousands to choose from. One you may want to try is carbohydrase - oit breaks down carbohydrates and its the reason why if you "suck" bread for a while in your mouth you get a sugary taste! If you need any help or more information then post back here and I'm shure someone will be able to help you (I'll try but I'm no master even though I've done this experiment 3, 4 times I still make errors ) Cheers & Good luck, Ryan Jones Edit: Here we go, have a look at the links below for informaiton on those two enzymes. Catalase, Carbohydrase and more on enzymes
  12. But something is better than nothing right? I'm quite interested in string theory at this point in time and I'm spending a lot of time thinking about it (At the expense of other things I must admit.) I string / M-Theory still a very active subject in physics today? Cheers, Ryan Jones
  13. From what I hear we have about 52% of the same [acr=Deoxyribonucleic acid]DNA[/acr] that a bannana(sp?) has! Thats pretty nuts when you think about it - hey mom, I'm half bannana! Cheers, Ryan Jones
  14. @yourdadonapogos: I said I'll understand them at a later time - right now I'd just like to look at them and if possible get a basic idea of what they are saying @Tom Mattson: I'll have a look at that site, thanks for the link! Cheers, Ryan Jones

    It all depends on the topics in Biology you are interested in and on how technical you'd like the work to be Heres one I have done a few times and shuld be relativly easy as long as the equiptment is provided for you Testing the effects of Ph, Heat, Preassure (May not be feasible) and concentrations on the effectiveness of enzymes. You could do a few test experiments for an enzyme in each catogory, take for example: Ph (Its the first one on my list ). You could test it with a range of acidity and alkelinity to see at which the enzyme works best. Then you'd move onto the other topic e.g. temperature. Test this the same way and record your results Then you could make a conclusion as too the best conditions required for the enzyme to work with the reasons why... you could even go nuts and try it with multiple enzymes. I did this a few times as I ahve said and this experiemnt has never failed to get me an A* grade in my school. As I said it all depends on what you like doing and are good at - I'm shure there are other people who can suggest more experiments for you to do, this jus thappens to be one of my favourites! Cheers &b Good Luck, Ryan Jones
