Some body changes that occur in males during puberty include:
Correct answer: C. Both A and B
- A. A deep voice
- B. Facial hair
- C. Both A and B
- D. None of the above
Explanation
During puberty, the larynx (voice box) grows larger and the vocal cords lengthen and thicken. This results in a deeper voice as the vibrations produced by the vocal cords resonate differently in the larger larynx.Puberty triggers the growth of facial hair, including the development of a mustache, beard, and sideburns. This is primarily due to an increase in testosterone levels, which stimulates the growth of hair follicles in the face.The correct answer is "Both A and B" - both a deep voice and facial hair growth are body changes that occur in males during puberty.
