Changes in the shape of a cell usually involve a reorganization of the
cytoskeleton.
Cytoskeleton is an interwind filamentous network that mainly keeps and mantains the shape as well as internal organization.
- Hence reorganization is also done with the help of the cytoskeleton.
- Extracellular matrix mainly helps the cell to keep it together.
- Transporter proteins mainly act as a catalyzing agent for various purposes.
- Nucleus is just a genetic material carrying an organelle that regulates the activities of cells.

Answer:
d. Estrogen will bind to a receptor protein that enters the nucleus and activates specific genes.
Explanation:
Estrogens are small lipophilic molecules synthesized from cholesterol. This steroid hormone (estrogen) is able to directly enter into the cell nucleus to bind with their corresponding receptors. Subsequently, estrogen-receptor binding stimulates these receptors to form dimeric structures that bind to DNA and thus activate gene expression. Estrogen receptors interact with DNA and activate gene expression through zinc finger domains composed of four (4) cysteine residues surrounding a zinc atom.
