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.
Just because you unlock your phone doesn't mean that you can use the phone on any network. The SIM card for the new network must compatible with the network your phone currently supports. The major networks -- T-Mobile, AT&T, Verizon and Sprint -- are either GSM or CDMA networks. Therefore, if your phone is a GSM phone, you can't use it on the Sprint network, as Sprint operates a CDMA-based network.
