Question

sex hormones affect all organs and systems of the body.
a true
b false

Explanation:

Sex hormones, such as estrogen and testosterone, play crucial roles in regulating various physiological processes. They influence the development and function of reproductive organs, but also have effects on other systems like the cardiovascular, skeletal, and nervous systems. For example, estrogen helps maintain bone density (affecting the skeletal system) and has impacts on blood vessels (cardiovascular system). Testosterone affects muscle mass (muscular system) and red blood cell production (related to the circulatory system). So, they do not just act on reproductive organs but have widespread effects across multiple body systems.

Answer:

A. True
