  1. Enzymes are a particular kind of protein that have the ability to catalyse reactions in living organisms. Proteins are very long chain molecules made up of amino acid building blocks. The protein chain is folded in a complex three dimensional shape known as its tertiary structure. The chain is held in this shape by interactions between different parts of the chain.

    Enzymes are classified according to the substances they act on. A specific enzyme will work on only one type of molecule. For example, an enzyme that breaks down proteins is called a "protease," and it will have no effect on fats, grease, starches, etc. Similarly, a lipase enzyme will break down animal fats and grease but will have no effect on proteins, paper, starch, etc. Many microbial drain and septic products available in the marketplace today feature only protease and amylase enzyme typesfor enzymes involved in the FA metabolism.

    im happy to help but next time, if u want someone to do ur homework for u try to do parts of it.

    Notice from jeigh:
    I'm glad that you're happy to help, but next time you qoute other sites put them in quote blocks and give the original site addy's

  2. If you use Windows, try VirtualDub and see if it can do the job.

    Download here: http://virtualdub.sourceforge.net/
    Home page: http://www.virtualdub.org/

    The current VirtualDub release package for Windows is
    "VirtualDub-1.6.14.zip". Download and unzip the .zip file
    into a new folder. Run VirtualDub.exe

    In VirtualDub's "File" menu, select "Open video file", and open the .avi file.

    In VirtualDub's "Audio" menu, select "No audio".
    In VirtualDub's "Video" menu, select "Direct stream copy".

    In VirtualDub's "File" menu, select "Save as AVI."
    Enter a new name and save the file.

    If VirtualDub reports errors and cannot continue,
    you may have encountered an AVI file that VirtualDub can't handle.


  3. Chromatography involves a sample (or sample extract) being dissolved in a mobile phase (which may be a gas, a liquid or a supercritical fluid). The mobile phase is then forced through an immobile, immiscible stationary phase. The phases are chosen such that components of the sample have differing solubilities in each phase. A component which is quite soluble in the stationary phase will take longer to travel through it than a component which is not very soluble in the stationary phase but very soluble in the mobile phase. As a result of these differences in mobilities, sample components will become separated from each other as they travel through the stationary phase.

    Techniques such as H.P.L.C. (High Performance Liquid Chromatography) and G.C. (Gas Chromatography) use columns - narrow tubes packed with stationary phase, through which the mobile phase is forced. The sample is transported through the column by continuous addition of mobile phase. This process is called elution. The average rate at which an analyte moves through the column is determined by the time it spends in the mobile phase.

     

    There's also paper Chromatography and it's pretty easy and useful, kind of old school, i mean not that accurate of a results and all but good enough...here's a link for how to do it :

    you can also check it out on wikipedia dude..here's the link:

  4. i love that option yeah, and i dunno about you guys, but if you have ever used their voice over IP chat , it's great and much clearer voice than msn from my own experience...i also wanted to add that i like the feature about gmail were it adds the email address you send to automatically to your address book, instead of asking and all...i think this is a cool feature


  5. u know what..i took a nutrition class and all that stuff talking about vitamins being like 2000% or 500% doesnt really matter. becuase once your body uses what it needs it secretes the rest out. also it might be toxic in some cases for some people..i like monster energy, just because it's so sweet, but i only drink it like in special cases when i really need to.


  6. i dont know if this is approved to be here, so i'll post it and will see what you guys think of it...i'm going to explain in this tutorial how to access wireless networks even though they might have a WEP code on them.i have not realized before that it could be that easy of a task, but i have found three programs till now that can do the job right.the first program is calle Airsnort. this program is like a tool that cracks WEP encryption codes or keys. what it does is it monitors the transmissions and then calculates the encryption key when it has gathered enough packets. for those who dont know what WEP means, WEP stands for Wired Equivalent Privacy. this is the encryption algorithm built into the 802.11 (Wi-Fi).the second program is a package called bsd-airtools, it currently contains a bsd-based (WEP) cracking application. It also contains a curses based ap detection application that can be used to detect wireless access points and connected nodes, view signal to noise graphs, and interactively scroll through scanned ap's and view statistics for each. it's probably harder to use than Airsnort since it has multiple applications.the third one is my favorite, it's called wepattack and it's a WLAN open source Linux tool for breaking 802.11 Wired Equivalent Privacy keys. This tool is based on an active dictionary attack that tests millions of words to find the right key. Only one packet is required to start an attack on WEP.download them and try..hope this tutorial was useful.


  7. to be honest with you..open office is great comparatively just because it hasnt been developed for long and it achieved so much, but ms office still has better stuff in it..like last time i was trying to insert page numbers and it inserted them wherever you put your mouse instead of showing you specific positions like ms word...and so on...it's nice as a free software and i use it, but it's a change down a little bit from ms word
