The change associated with sexual maturation in boys is cracking of voice.
Explanation:
Cracking voice:
This is a distinct change that occurs in boys during puberty due to the growth of the larynx and vocal cords, caused by the surge of testosterone.
Other changes during adolescence:
While other options like increased height and weight gain also occur during puberty, they are not specifically linked to sexual maturation. Losing milk teeth is a developmental change that happens in childhood, not during adolescence.
Why other options are incorrect:
Loss of milk teeth:
This is a normal developmental process that occurs in both boys and girls during childhood, typically between ages 5 and 13. It’s not considered a change associated with sexual maturation.
Increase in height:
Although height increases are a significant part of puberty, they are not directly tied to sexual maturation. Both boys and girls experience this growth spurt.
Weight gain:
Weight gain is another common physical change during adolescence, but like increased height, it’s not solely related to sexual maturation. It’s a result of hormonal changes and increased bone and muscle mass.
