Answer:
internal receptor binding
Explanation:
This is because steroid hormones are lipids by nature (usually composed of cholesterol) so they are hydrophobic. This means that steroid hormones can easy pass through the membrane and bind to their internal receptors.
Internal receptors also known as intracellular receptors have DNA binding domain and when hormones bind to them DNA-binding site becomes exposed. Hormone-receptor complex gets into the nucleus and binds to regulatory regions of the DNA. Cellular response is gene expression.
The appropriate response is Smooth muscles. Smooth muscle is found in the dividers of empty organs like your digestion tracts and stomach. They work naturally without you monitoring them. Smooth muscles are associated with many 'housekeeping' elements of the body. The strong dividers of your digestive organs contract to push nourishment through your body.
