Variations are caused by mutation. random mating between organisms.
Explanation:
The gas exchange during cellular respiration involves oxygen moving into cells and carbon dioxide moving out of cells.
During gas change oxygen actions from the lungs to the bloodstream. on an equal time, carbon dioxide passes from the blood to the lungs. This happens within the lungs among the alveoli and a network of tiny blood vessels known as capillaries, which might be located in the walls of the alveoli.
Three strategies are critical for the switch of oxygen from the out of doors air to the blood flowing through the lungs: airflow, diffusion, and perfusion. ventilation is the manner through which air moves in and out of the lungs.
The lungs and respiratory system permit us to respire. they create oxygen into our bodies (called a concept, or inhalation) and send carbon dioxide out (referred to as expiration, or exhalation). This alternate of oxygen and carbon dioxide is referred to as respiratory.
