Examples of steroid hormones are estrogen, progesterone, and cortisol. Thus, the correct answer is 'option b). they serve as chemical messengers.'
Ответ:
They serve as chemical messengers.
Explanation:
Steroid may be defined as the molecule that are made of large number of non polar molecules and are hydrophobic in nature. The cholesterol is an important steroid present in mammals.
