The intracellular fluid of inside a cell called the cytosol. It is separate from certain cell organelles such as the nucleus and the mitochondria. In eukaryotes, the cytoplasm is the content within a cell membrane minus the content in the cell nucleus.n the other hand, cells such as eukaryotes cell the cytosol containing the cell's genome is held within the cell nucleus, which then separates from the cytosol by nuclear pores that blocks the free diffusion of any kind of molecule that is larger than 10 nm in diameter.
Iron (Fe) is the second most common metal on Earth, and the most widely-used metal. It is element 26, a transition metal in Group 8. Its symbol is Fe, from the Latin word for iron, ferrum.Its atomic number is 26 and its mass number is 55.85.ron (Fe) is the second most common metal on Earth, and the most widely-used metal.

Â­Steel is iron that has most of the impurities removed. Steel also has a consistent concentration of carbon throughout (0.5 to 1.5 percent). Impurities like silica, phosphorous and sulfur weaken steel tremendously, so they must be eliminated.The advantage of steel over iron is greatly improved strength.hen the carbon content is right, you have carbon steel. Another way to create steel from pig iron is the Bessemer process, which involves the oxidation of the impurities in the pig iron by blowing air through the molten iron in a Bessemer converter.
