Let's solve this step by step. The task is to identify whether each physical change during puberty occurs in
boys (B),
girls (G), or
both (T).
Here’s the list of changes and the correct answers with explanations:
---
1.
Pimples may start to appear on the face.
✔ Answer: T
✔️
Explanation: Acne (pimples) can occur in both boys and girls during puberty due to increased hormone levels (especially androgens), which stimulate oil production in the skin.
---
2.
The breasts start to develop.
✔ Answer: G
✔️
Explanation: Breast development is a primary sign of puberty in girls. It does not occur in boys.
---
3.
The voice will break.
✔ Answer: B
✔️
Explanation: Voice deepening and "breaking" happens in boys due to the growth of the larynx and vocal cords caused by testosterone. This does not happen in girls.
---
4.
The lengthening of the penis.
✔ Answer: B
✔️
Explanation: This is a male-specific change during puberty. The penis grows in size as part of sexual maturation in boys.

5.

✔ Answer: T
✔️
Explanation: Pubic hair growth is a common sign of puberty in
both boys and girls, though the pattern may differ.

6.
The hips become wider and rounder.

7.
Facial hair will start to grow.
