which is one factor that internally influences the onset of puberty?\n○ exposure to toxins\n○ nutrition\n○ hormone levels\n○ social stressors

Answer

Brief Explanations:

To determine the internal factor influencing puberty onset, we analyze each option:

  • "Exposure to toxins" is an external environmental factor.
  • "Nutrition" can be influenced by external factors (e.g., food availability) and is more about external input affecting internal processes, but not purely internal.
  • "Social stressors" are external (related to social environment).
  • "Hormone levels" are internal physiological factors that directly regulate puberty onset, as hormonal changes (e.g., gonadotropin - releasing hormone, sex hormones) are part of the body's internal system triggering puberty.

Answer:

B. hormone levels
