Answer:
Diffusion
Explanation:
The movement of molecules and ions from a region of higher concentration gradient to the region of lower concentration gradient of the molecules. Its direction of movements depends totally on the direction of the concentration gradients.
Fick's Law is the principal law that underscores diffusion. And it sates that the rate of diffusion is directly proportional to the concentration gradients or differences; the surface area available for the molecules to pass through ;<u> but inversely proportional to the thickness of the separating membrane (diffusion distance. </u>
<u />
<u />
Thus the larger the surface area exposed the more molecules pass through into the membrane , the higher the concentration differences the greater the number of molecules willing to break free and escape; but the thicker the separating membranes, the slower the number of molecules getting chances to pass through and the lower the rate of diffusion.
Answer:
The residual volume is the amount of air remaining in the lungs after a forced expiration.
The volume of air exchanged during normal breathing is called the tidal volume.
After a normal inspiration, the amount of air that can then be inspired forcefully is called the inspiratory reserve volume .
If you subtract the residual volume from the total lung capacity, you get the vital capacity.
The vital capacity minus the expiratory reserve volume equals the inspiratory capacity.
The effects of obstructive diseases such as asthma or emphysema may be determined by measuring the forced expiratory volume .
True is the answer
Incorrect use of drugs could cause an overdose, which could eventually lead to death
Incorrect use of dietary supplements ( lets say you take different type of supplements without knowing what you're doing) , could create a toxic result for your body, which also could eventually lead to death
