Explanation:

Analyze the cellular pathway

The diagram illustrates how a lipid-soluble or steroid-like hormone acts on a target cell to trigger gene expression and protein synthesis. We trace the pathway from secretion to the final cellular response.

Identify the first step

The hormone is secreted by endocrine tissue and travels to the target cell. The first empty box on the left points to the interaction between the hormone and its receptor on the cell membrane. This corresponds to the label: "binding of the hormone molecule with its receptor of the cell".

Identify the second step

Once the hormone binds to its receptor, a signal is transmitted into the nucleus. The second empty box on the left points directly to the transcription process occurring on the DNA inside the nucleus. This corresponds to the label: "formation of mRNA in the nucleus".

Identify the third step

Following transcription, the mRNA is translated in the cytoplasm. The third empty box on the left points to the translation machinery (ribosome, mRNA, and tRNA) synthesizing a polypeptide. This is already labeled in the diagram as "synthesis of protein molecule by mRNA and tRNA".

Identify the final step

The newly synthesized protein is processed and released from the cell. The empty box on the bottom right points to the exit of the new protein from the cytoplasm. This corresponds to the label: "secretion of protein by the cell".

Evaluate unused labels

The label "initiation of DNA replication because of a signal given by the hormone" is incorrect because the diagram depicts transcription (mRNA synthesis) and translation (protein synthesis) rather than DNA replication.

Answer:

The correct labels for the empty boxes in the diagram, from top to bottom on the left and then the bottom right, are:

• Top-left box (pointing to hormone-receptor binding):

"binding of the hormone molecule with its receptor of the cell"

• Middle-left box (pointing to transcription in the nucleus):

"formation of mRNA in the nucleus"

• Bottom-right box (pointing to the release of the new protein):

"secretion of protein by the cell"
