Complex systems are modeled on computers. Computer models are used to study systems that cannot be studied directly. heart attacks Normal heartbeat effect of medicines on the human body movement of water molecules into and out of a cell spread of a disease through a population Heart attack Computer models are used when experiments are not safe, ethical, or practical.

The tools of molecular genetics give rise to new biological studies. A gene is a segment of DNA that stores genetic information.

Through our understanding of DNA, we can study genetics on a molecular level. molecular genetics genomics
