Steroid hormones bind to
a. carbohydrate receptors on the cell membrane of the target cell.
b. carbohydrate receptors in the cytoplasm of the target cell.
c. protein receptors on the cell membrane of the target cell.

option c.

Steroid hormone bind to protein receptors on the cell membrane of the target cells.

Explanation:

Steroid hormone are fat soluble substance that act as hormones. Examples of steroid hormone are oestrogen female sex, androgen, progestin e.t.c. They are found in the nucleus, cystosol and cell membrane of the target cell.

They bind to protein receptors of the target cell membrane to initiate signal transduction and gene expression.

the cladogram shown here shows similarities and differences among several classes of vertebrates. anatomically, the four have limb structure as their common ancestor. we might separate the mammals from the other three classes because they a) divergent; do not lay eggs b) identical; are warm-blooded c) varied; a four chambered heart d) homologous; have mammary glands

layer 3 is younger than layer 6.
