Question

A. Complete the following written exercise Diffusion of gases through a liquid. When several or molecules are present consider only one case of diffusion at a time even though several different types of molecules are moving In the lungs, there are a series of tubes that transport gases. These tubes become very small and eventually end at a series of alveolar sacs. Adjacent to these sacs are a number of blood capillaries. By the process of diffusion, there is an exchange of oxygen and carbon dioxide between the alveolar sacs and the blood in the capillaries. 1. Draw a blue arrow on figure 3.3 to indicate the net direction of carbon dioxide mover 2. Draw a red arrow on figure 3.3 to indicate the net direction of oxygen movement. IN CO, Os Blood 125 9. Figure 3.3 Diffusion of oxy and carbon 3. On figure 3.4, draw a red arrow to show the net direction of sugar movement. 100% 100 Fipe . Super die

COg and Og both more. T to lowel concentration from their higher concentration 3. On figure 3.4, draw a red arrow to show the net direction of sugar movement. Sugu moves from its higher concentration 100 to lower mentation 1. Sup di * Lone

This is according to the law of diffusion. According to this law, substances diffuse from the region of their higher concentration to lower concentration.
