Answer:

1000 times.

Explanation:

Hello,

In this case, since the pH is defined by:

pH=-log([H^+])

If we want to compute the concentration of hydrogen we must write:

[H^+]=10^{-pH}

Thus, for both the backyard soils we compute:

[H^+]_{pH=7}=10^{-7}=1x10^{-7}M

[H^+]_{pH=4}=10^{-4}=1x10^{-4}M

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

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:

DNA structure and function. DNA is the information molecule. It stores instructions for making other large molecules, called proteins.  Each gene stores the directions for making protein fragments, whole proteins, or multiple specific proteins. The sequence of bases in a DNA molecule can determine the order of amino acids in a protein molecule. Groups of three bases called triplets represent different amino acids. This is the basis of the genetic code . A sequence of bases (genetic information) on DNA that codes for a protein is called a gene .
