You measure the pH of your backyard soil and find it is 7. You measure the pH of your friend's backyard soil and find it is 4. H
olchik [2.2K]

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.

Which viral genome is likely to require an RNA-dependent RNA polymerase for transciption upon viral entry?
Inga [223]

Answer:

(-) sense single-stranded RNA

Explanation:

Negative sense refers to viruses that use the negative sense single stranded RNA as their genetic material.

It is essential for the negative viral strand is complimentary to the mRNA so it is converted to a positive RNA by RNA polymerase.  

Negative sense single stranded RNA virus require an RNA dependent RNA polymerase for transcription.  This is because it essential in encoding proteins by catalyzing the complimentary RNA strand to the given RNA tempelate.
