Biologists can use different methods and tools to support their research, and the use of advanced technologies such as DNA chips, electron microscopes and satellites help advance the field of biology. Marine biologists use global positioning satellites to record the location of marine animals through devices that transmit the location to a satellite that transmits information to biologists. This technology assists in analyzing knowledge of important characteristics and behaviors of marine animals.
After oxygen was distributed to somatic cells, there are higher concentraion of carbon dioxyde. Therefore, it will move out from our cell to be exhaled by lungs. Vice versa for oxygen
