Question

name:

1. acne, loss of scalp hair, facial hair growth and color, and darker skin pigmentations are some of the resul

changing or fluctuating ____.
a. cells
b. tissues
c. hormones
d. metabolism

Explanation:

To solve this, we analyze the options:

• Option a (cells): Cells are basic units, but the changes (acne, hair, skin pigment) relate to hormonal influences on body systems, not just cells.
• Option b (tissues): Tissues are groups of cells, but the symptoms are due to hormonal changes affecting multiple body processes, not just tissues.
• Option c (hormones): Hormones regulate growth, development, and physiological processes. Puberty - related changes like acne, hair growth, and skin pigmentation are due to fluctuating hormones (e.g., sex hormones, androgens).
• Option d (metabolism): Metabolism is about energy use and chemical reactions. The listed symptoms are not primarily metabolic changes.

So the correct answer is related to hormones.

Answer:

c. hormones
