  1. New pic from the field. For scale' date=' the snake is 1.83 m without tail, 2.3 m with tail, and the marks on the pole are 20 cm apart. It's a Brown Tree Snake, which you'll see more about in my upcoming field report.

    I was staring too hard at the sideburns to realize that there was a snake on the pole... but anyways whats a hemipenes? a half penis? how does that work? maybe its the snakes counterpart of being limb?

  2. I read an article back in 9th grade that glass was an uber viscous fluid. Apparently they measured the glass murals of ancient cathedrals and found that the bottom of the glass was thicker than the top of the glass. Any one know how or what contributes to its viscousness?

  3. Energy is actually usually stored in the form of sugars and fats. ATP is the intermediary and there is a tightly regulated ratio of ATP/ADP at any given time in the cell.

     

    By storage I meant that ATP was the energy currency for cells. Because the phosphate bonds in ATP contains a high level of energy. The human body has a about 0.1 moles of ATP, yet we consume ~200-300 moles a day. Meaning that it is heavily recycled.

  4. Energy is usually stored in the form of ATP (adenosine triphosphate, IIRC which is an adenine nucleoside attached to three phosphate groups.)

     

    ATP is pretty much required for everything from photosynthesis to respiration, it's needed to power the sodium potassium pump. ATP is often converted from ADP or AMP, and vice versa. There are countless varieties of kinases that facilitate this process.

  5. Lol its alot more than cell divisons. The mitotic machinery itself is far from perfect, as the DNA repair mechanisms do fail once in a while. Slowly the somatic damage accumulates. There are also plenty of societal influence as well. Like I said in your other thread, you need to be more specific, I don't even know where to start.

  6. lol your still being a bit too general. By exactly the same do you mean exactly the same genetically speaking? or molecularly speaking? Because it is impossible to have an exact Carbon copy.

  7. lol we have barely existed for more than 5000 years with regards to our level of advancement, who are we to say that we are the most advanced. I'm sure that dinosaurs thought they were the most advanced as well, and well you know the rest of the story.

  8. Zyncod, so what you are saying is that the dendritic cells actually have the ability to kill T-cells? If so, would you know where to find information on the signaling mechanism? So unless the T-Cell is activated, it will just keep on going killing dendritic cells?

     

    I understand your little tid-bit about the MHCII presenting antigen part, thanks.

     

    Also, just to double check, when the dendritic cells have been infected by viral particles, the cell presents its own antigens via only the MHCI (as opposed to MHCII) mechanism?
