Answer:
B. Estrogen binds to specific receptors inside many kinds of cells, each of which have different responses to its binding.
Explanation:
Estrogen is a lipid-soluble steroid hormone and binds to its receptors present inside the target cells. Estrogen binds to specific receptors in different types of cells. Binding of estrogen to a specific receptor in a cell would initiate the specific cellular response. Likewise, binding of estrogen to its receptors in some other cell type would generate a different cellular response. For example, binding of estrogen to transcription factors in the cells of mammary glands may stimulate cell division and differentiation to trigger the development of mammary glands at puberty in females.

It is located at the end of the external canal and has a shape of a flattened cone with the apex pointing inward. It is also called the eardrum. It has three layers which are the outer layer which is continuous with the skin, the inner layer which is continuous with mucous membrane and in between a radial layer of fibers which gives the membrane its stiffness.
