Water dissolves gases and allow for efficient exchange and transport of oxygen and carbon dioxide. What does this mean some are born great some achieve greatness and some have greatness thrust upon them? 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). 9.6) the effects on fish may include: death damage to outer surfaces like gills eyes and skin and an inability to dispose of metabolic wastes. Some biological systems, however, use positive feedback loops. Pure water has an equal amount of hydrogen and hydroxide ions making the pH perfectly balanced. When such a system is disturbed, built-in regulatory devices respond to the departures to establish a new balance; such a process is one of feedback control. For this process to function properly, homeostasis helps our body to keep both water and salt balance level. I didn't understand the concept from the article. From what I understood, negative feedbacks is your body's response to keep things normal or stable, whereas positive feedbacks exacerbate certain effects on the body by repeating functions deliberately.
