Animal Cells. Most animal cells are between 10 to 100 microns in size. The size depends partially on the type of cell and its function. Red blood cells, which don't need to divide and replicate are only about 8 microns in diameter, while many muscle and nerve cells are thin, spindly and extremely long.nimal Cells.

A cellular phone that uses the Global System for Mobile (GSM) network and can access multiple cellular phone service provider networks is called an unlocked GSM phone. A locked cell phone is sold by the cell phone service provider and cannot be used with any other provider.
Whereas a locked cell phone will only accept SIM cards from its current provider, an unlocked cell phone will accept a SIM card from any service provider. (This is very useful if you want to use your phone abroad, for example.) To identify an unlocked cell phone, follow these steps.. Power down your cell phone, remove the battery cover and battery, then look for the SIM card. 1  If you cannot find a SIM card in the back, look for one in the side or top of the phone.
