Answer:
1000 times.
Explanation:
Hello,
In this case, since the pH is defined by:
![pH=-log([H^+])](https://tex.z-dn.net/?f=pH%3D-log%28%5BH%5E%2B%5D%29)
If we want to compute the concentration of hydrogen we must write:
![[H^+]=10^{-pH}](https://tex.z-dn.net/?f=%5BH%5E%2B%5D%3D10%5E%7B-pH%7D)
Thus, for both the backyard soils we compute:
![[H^+]_{pH=7}=10^{-7}=1x10^{-7}M](https://tex.z-dn.net/?f=%5BH%5E%2B%5D_%7BpH%3D7%7D%3D10%5E%7B-7%7D%3D1x10%5E%7B-7%7DM)
![[H^+]_{pH=4}=10^{-4}=1x10^{-4}M](https://tex.z-dn.net/?f=%5BH%5E%2B%5D_%7BpH%3D4%7D%3D10%5E%7B-4%7D%3D1x10%5E%7B-4%7DM)
It means that:
![\frac{[H^+]_{pH=4}}{[H^+]_{pH=7}} =\frac{1x10^{-4}M}{1x10^{-7}M}\\ \\\frac{[H^+]_{pH=4}}{[H^+]_{pH=7}}=1000](https://tex.z-dn.net/?f=%5Cfrac%7B%5BH%5E%2B%5D_%7BpH%3D4%7D%7D%7B%5BH%5E%2B%5D_%7BpH%3D7%7D%7D%20%3D%5Cfrac%7B1x10%5E%7B-4%7DM%7D%7B1x10%5E%7B-7%7DM%7D%5C%5C%20%5C%5C%5Cfrac%7B%5BH%5E%2B%5D_%7BpH%3D4%7D%7D%7B%5BH%5E%2B%5D_%7BpH%3D7%7D%7D%3D1000)
It means that the concentration of hydrogen at a pH of 4 is 1000 times greater than the concentration of hydrogen at a pH of 7.
Regards.

Explanation:
high muscle capillary density means a large muscle-to-blood exchange surface area, short oxygen diffusion distance, and high red blood cell mean transit time.Capillary action is important for moving water (and all of the things that are dissolved in it) around. It is defined as the movement of water within the spaces of a porous material due to the forces of adhesion, cohesion, and surface tension.
