Question

1. which of the following is a primary sex characteristic that develops during puberty? (1 point) a facial hair growth in males b increased breast size in females c growth in height d deepening of the voice in both males and females

Explanation:

Primary sex characteristics are directly related to reproduction. Facial hair growth in males is a secondary sex - characteristic related to sexual dimorphism but not directly involved in reproduction. Growth in height is a general growth - related change during puberty, not a primary sex characteristic. Increased breast size in females is a secondary sex characteristic. The deepening of the voice in both males and females during puberty is also a secondary sex characteristic. However, among the options, the others are secondary sex characteristics, and there is no correct option for a primary sex characteristic as none of these choices are primary sex characteristics.

Answer:

None of the above options are primary sex characteristics.
