Feedback Mechanisms How do organisms regulate complex systems through chemical interactions? Why? The heating system of a house works to keep the temperature constant. If the house gets too cold‚ then the heat automatically turns on to warm the house. The heat stops when the preset temperature is reached. This is an example of a feedback mechanism. Organisms use many feedback mechanisms to either maintain or amplify important chemical systems. This could happen at a molecular level to coordinate

once-healthy neurons (nerve cells) in the brain stop working‚ lose connections with other brain cells‚ and die. While everyone loses some neurons as they age‚ people with dementia experience far greater loss. Researchers are still trying to understand the underlying disease processes involved in the disorders. Scientists have some theories about mechanisms that may lead to different forms of dementias‚ but more research is needed to better understand if and how these mechanisms

Homeostatic Mechanisms Homeostatic mechanisms are essential for a body to maintain a stable condition. The word homeostasis describes the body’s ability to maintain its healthy state‚ while the world around it is changing constantly. There are many steps in the process of homeostasis. First‚ there is the stimulus that causes the change. Then the receptor detects the change. The information of the imbalance is then sent to the control center‚ which decides the response. The information entering into
