Final answer:

Steroid hormones are lipids that can diffuse across cell membranes and bind with receptors in the cytoplasm. The hormone-receptor complex then moves to the nucleus and influences gene expression. Steroid hormone receptors function through gene activation by binding to specific DNA sequences.

Step-by-step explanation:

Steroid hormones are made of lipids and are fat-soluble, allowing them to diffuse across the plasma membrane of target cells and bind with receptors in the cytoplasm of the cell.

The steroid hormone-receptor complex then moves into the nucleus and influences the expression of genes, acting as a transcription factor.

Steroid hormone receptors are generally soluble proteins that function through gene activation, binding to specific DNA sequences and regulating transcription.
