Answer:

the answer is evolution  the other person made me get it wrong

Explanation:

Individuals within populations exhibit some diversity. As a result of possessing slightly different traits, some individuals are better able to survive and reproduce than others. As these individuals are naturally selected, changes in the characteristics of the populations may occur over time. The cumulative change in these characteristics is known as evolution.

So, natural selection is the primary mechanism for evolution.

The normal range of the pH of blood is between 7.35 and 7.45; variations beyond this range have significant health implications.
patriot [66]

Answer:

The hydrogen ion concentrations associated with these pH value 7.35 is 4.5\times 10^{-8} M

The hydrogen ion concentrations associated with these pH value 7.45 is 3.6\times 10^{-8} M.

Explanation:

To calculate the pH of the solution, we use the equation:

pH=-\log[H^+]

We are given:

1) pH = 7.35

Putting values in above equation, we get:

7.35=-\log[H^+]

[H^+]=4.467\times 10^{-8} M\approx 4.5\times 10^{-8} M

The hydrogen ion concentrations associated with these pH value 7.35 is 4.5\times 10^{-8} M

2) pH = 7.45

Putting values in above equation, we get:

7.45=-\log[H^+]

[H^+]=3.548\times 10^{-8}M \approx 3.6\times 10^{-8} M

The hydrogen ion concentrations associated with these pH value 7.45 is 3.6\times 10^{-8} M.
