Stem cells look like a hollow sphere composed of a clump of tiny, roundish balls. In reality, they are much more than that. Forty cells contain all the potential to become a living, breathing human being. Many scientists believe that these cells also can cure a myriad of diseases, including Alzheim...

The mitochondrion is an organelle found in eukaryotic cells (Tortora 1992). A mitochondrion can occur in different shapes inside one cell. Mitochondrion can be long, like a rod, and filamentous or compact, like a sphere, and granulelike (Wolfe 1993). There are approximately 1700 mitochondria in...
ATM stands for Asynchronous Transfer Mode. It is a high speed mode of transporting data from one point to another. With ATM, you are able to transmit voice, data and video in small data packets over a single network. It can carry traffic at speeds up to 622 Mbps. Data is transmitted in fixed lengt...
