A . This cookie is set by GDPR Cookie Consent plugin. What is an example of homeostasis in a living thing? High pH may also increase the toxicity of other substances. All living things are water-based systems, which means that they depend heavily on aqueous equilibria, especially acid-base equilibria. When we eat food the bacteria present in our mouths break down the sugar to form acids. Homeostasis helps animals maintain stable internal and external environments with the best conditions for it to operate. This ensures that the cells environments are maintained at the proper pH in order for their biomolecules to maintain their functionality and so that their enzymes can function properly. The stimulus is when the body temperature exceeds 37 degrees Celsius, the sensors are the nerve cells with endings in the skin and brain, the control is the temperature regulatory center in the brain, and the effector is the sweat glands throughout the body. The cells between your embryonic fingers died in a process called apoptosis, a common form of programmed cell death.In programmed cell death, cells undergo "cellular suicide" when they receive certain cues.Apoptosis involves the death of a cell, but it benefits the organism as a whole (for instance, by letting fingers develop or eliminating potential cancer cells). In contrast, positive feedback loops push the organism further out of homeostasis, but may be necessary for life to occur. You also have the option to opt-out of these cookies.
