I belive you mean the NIH 3T3 cell line which is the mouse embryonic fibroblast cell line, capable of differentiating into multiple cell types - adipocytes, myocytes or chondrocytes.
The dialysis tubing in the lab is representing the cell membrane of a cell. Like the cell membrane, the dialysis tubing is selectively permeable, allowing only certain molecules to pass through based on size and charge. This setup is used in experiments to study osmosis and diffusion, which are also important processes regulated by the cell membrane.
The average epithelial Onion Cell is 30.2 to 35.4 micrometers in diameter. I just did this exercise in cell bio lab.
In a modern lab, you would use a digital scale to measure mass. Historically, balances and spring scales were used.
i wish i knew bro
-3t3 + 23t2 + 8t = -t(3t2 - 23t - 8) = -t(3t + 1)(t - 8)
3t3 is the same as 9t because multiplication is commutative. 5 * 9t = 45t. If you meant 3t^3, then 3t^3 * 5 = 15t^3.
I belive you mean the NIH 3T3 cell line which is the mouse embryonic fibroblast cell line, capable of differentiating into multiple cell types - adipocytes, myocytes or chondrocytes.

you sure you dont mean a single protein cell? if you do the answer is no.
To properly use a hemocytometer for cell counting and analysis, first prepare a cell suspension and load it onto the hemocytometer. Then, place the hemocytometer under a microscope and count the cells in the grid squares. Calculate the cell concentration and analyze the data to determine cell viability or other characteristics. Remember to follow proper lab safety protocols and clean the hemocytometer after each use.
-(t(3t + 1)(t - 8))
A microscope is the best tool to use in a school science lab to see the cells in a growing root. It allows for high magnification and detailed observation of cell structures. Choose a compound light microscope for this purpose.
There can be a variety of reasons to prohibit cellphones in laboratories. They include the following:Laboratory work requires your full attention. If you don't have your cell phone at hand, you are not likely to be distracted by it.Working in a laboratory often involves the use of hazardous chemicals, from which you are usually protected by the use of gloves or by other procedures. However, if you use your cell phone in the lab, you are likely to do so without removing your gloves and may then contaminate your cell phone.Some lab activities involve a potential for creation of a flammable atmosphere. Depending on the nature of the flammable materials present in vapor form, a cell phone signal may have enough energy to ignite the vapor.
