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 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.
You follow them when you are in the laboratory.

-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.

you sure you dont mean a single protein cell? if you do the answer is no.
-(t(3t + 1)(t - 8))

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.
