Class A (type D) CpG ODNs (CpG-A ODNs) contain a central palindromic phosphodiester (PO) CpG sequence and a PS-modified 3â poly-G tail. The poly G tails form intermolecular tetrads that result in high molecular weight ordered structures.
Why does a tornado form when cold and hot air meet? The collision of warm and cold air is not the direct cause of a tornado, nor is it absolutely necessary. When a cold air mass pushes into a warm air mass (this is called a câ¦old front) the warmer, less dense air is forced upwards.
The tornado in a bottle goes pretty fast. It has the speed winds of 60 mph. It doesn't match up with the real tornadoes. Conclusion I can say that my hypothesis failed but that I enjoyed doing my experiment. So my hypothesis didn't work but at least I learned something. Tornado in a bottle Materials â¢ Plastic bottle with cover â¢ Water â¢ Salt â¢ Teaspoon â¢ Liquid detergent â¢ Food coloring The speed of a tornado!! Hypothesis If I research how much the speed of a tornado is will it be the same as the tornado in the bottle? Experiment Independent Variable The independent variable will be the different locations of the tornadoes. Constant The constant will be the tornadoes and the materials I will use, The dependent variable will be the wind speeds of both tornadoes. Dependent variable By Katie Vega
