Which of the following is an example of an acquired characteristic? A. a dog that has curly hair just like its mother
B. a fish that grew larger after it was placed in a larger tank
C. a little girl that has long blonde hair just like her mom
D. a teenage boy that is as tall as his dad

B

Explanation:

most of the times acquired characteristics are behaviors that help an organism survive.

i'm assuming that the correct answer is indeed the first one/ "a"..

so here we go

atomic mass

239 + 1 = y + 134 + 3 combine like terms

240 = y + 137             subtract 137 from both terms

240 - 137 = y

103 = y

atomic number

94 = z +54 + 0

94 = z + 54               subtract 54 from both sides.

40 = z
