A solution with a pH of 7 Select one:

a) Contains an equal concentration of hydronium and hydroxide ions

b) Contains no hydronium or hydroxide ions, just water

c) Contains more hydronium ions than hydroxide ions

d) Contains less hydronium ions than hydroxide ions

C.

Explanation:

The hydronium ion concentration can be found from the pH by the reverse of the mathematical operation employed to find the pH.

due to the fact that it skipped a generation we can tell it is definitely not a dominant trait, therefore it must be recessive. i think this is right let me know!

explanation:

the answer is true when observing or determining population size, a direct observation is use, in which each organism is counted in a population or in an area. one benefit of this measure is that you get the exact population count but it will take a long time to  determine  the  size  of a  population.
