Carbon-14, 14C, or radiocarbon, is a radioactive isotope of carbon with a nucleus containing 6 protons and 8 neutrons. Its presence in organic materials is the basis of the radiocarbon dating method to date archaeological, geological, and hydrogeological samples. Carbon-14 was discovered on 27 February 1940, by Martin Kamen and Sam Ruben at the University [...]
Interphase Cell is performing for mitosis process. Chromosomes are not clearly seen and nucleus may be visible at the stage. Prophase Chromatin becomes visible. Nucleus disappear. Centrioles moves in opposite direction. Fibers extends to the from the centromers. Some fibers cross the cell to form the mitotic spindle. Metaphase Spindle fibers align the chromosomes along [...]
These are some of the fun Science or Chemistry experiment. Hope all the PTSM is having fun with the experiment utilizing Dry ice. This is one of the coolest science experiment in the world. Hope you guys love science.
