검증된 단계별 안내1
Understand the concept of puberty: Puberty is the period during which an individual undergoes physical and hormonal changes that lead to sexual maturity. It typically occurs during adolescence.
Identify the key features of puberty: Puberty is marked by the development of secondary sexual characteristics, such as breast development in females, deepening of the voice in males, growth of pubic and underarm hair, and changes in body composition.
Eliminate incorrect options: Onset of menopause occurs much later in life, typically in middle age, and is not related to puberty. Loss of baby teeth happens earlier in childhood, before puberty begins. A decrease in metabolic rate is not a characteristic of puberty.
Focus on the correct option: Development of secondary sexual characteristics is a hallmark of puberty and indicates the body's preparation for reproductive capability.
Conclude the reasoning: Based on the biological definition and characteristics of puberty, the correct answer is 'Development of secondary sexual characteristics.'
