Explanation:
Safranin is used to prepare an onion peel slide. Explanation: We use this strain because this strain can differentiate the region of the cells darker than the other regions.
Answer:
2.67 cells at 500x magnification...
Explanation:
So, four cells are present at 200x magnification and are covering the full diameter of lens. by using a 500x magnification, it means that magnification is increased 1.5 times. So, the number of cells visible will be decreased by a factor of 1.5. So, decreasing 4 cells by a factor of 1.5 means <em>2.66666666667</em> or <em>2.67</em> cells at 500x magnification. Resolution has to be increased by a factor of 1.5 to produce a view-able clear image of cells.
In eukaryotic cells, the mRNA is processed and migrates from the nucleus into the cytoplasm. mRNA carries coded information to the ribosome where this information is translated and used for protein synthesis.
Nucleus is like the brain of the cell. It is a double membranous organelle that regulates all the actions of the cell. Nucleus is also the store house of the genetic material. The cell membrane of the nucleus contains various small pores that manage the transport of molecules across it.
Ribosome is a nucleoprotein that is involved in the synthesis of protein. It has two subunits: a smaller one and a larger one. There are two types of ribosomes: 70 S and 80 S.
