c) a pupa forms around a caterpillar as it morphs into a butterfly.

C

Explanation:

The definition was GROW & CHANGE. This is the only answer that shows growing & changing.

The answer would probably be C as it says “one of those characteristics is the ability to grow and change” which C says “ pupa forms around a caterpillar as it morphs into a butterfly” and it is stating the change that happens between a pupa, caterpillar, and butterfly

when [oh-] is 10-5  m, and [h3o+] is 10-9  m, the poh is 5 and ph is 9. again in both cases the sum of ph and poh is 14. however, the hydrogen ion concentration is not always going to be equal to exactly 1 x 10 raised to a negative number. for example, we skipped over the value of 2.0 x 10-7.
