Why are hydrogen bonds important in biology. The stability that the organism reaches is rarely around an exact point (such as the idealized human body temperature of 37 C [98.6 F]). 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). If the pH of a living organism is too low, the solutions in the body will be too acidic. Scientists communicate how acidic a solution is using numbers on a pH scale. The optimum point in the body is being continuously monitored by receptors. If you get either too hot or too cold, sensors in the periphery and the brain tell the temperature regulation center of your brainin a region called the hypothalamusthat your temperature has strayed from its set point. The maintenance of the conditions by homeostasis is very important because in the wrong body conditions certain processes (osmosis) and proteins (enzymes) will not function properly. come to a river and find a boat that holds two.
