Steroid hormones bind to receptors in the nucleus of their target cells. cannot diffuse through cell membranes. remain in circulation for relatively short periods of time. are transported in the blood dissolved in the plasma. are proteins.

The correct answer is - bind to receptors in the nucleus of the target cells.

Explanation:

Steroid hormones are the chemical compounds that are a member of the class of steroids and act as hormones. These hormones are released by the adrenal cortex, testes and ovaries in the body placenta also release steroid hormone during pregnancy.

The steroid hormones do not bind to the plasma membrane of the target cell but binds to the receptors present on the nucleus of the cell. These cells pass through the cell and reach the nucleus and bind to it or gene to produce proteins for the biological process.

Thus, the correct answer is - bind to receptors in the nucleus of the target cells.
