1) usually do girls grow taller than boys in puberty.(please first give the answer in yes or no and explain)

 

2)what is the difference between enzymes and harmones.

1.Boys and girls are actually about the same height on average, until they reach the age of 12 or 13 (age of puberty). After that age, girls growth starts to level off. Boys continue growing until age 17 or 18. The reason why boys are taller than girls is their growth occurs very rapidly at the end of puberty. This delay gives boys the advantage of an additional two years of normal childhood development.
