Vladimir79 [104]

Answer:

Nucleolus

Explanation:

The nucleolus is a compact structure present in the nucleus of fungal cells and all other eukaryotic cells. The nucleolus is not enclosed by a membrane. Nucleolar organizer present in the nucleolus contains the instructions for the synthesis of ribosomal RNAs.

Ribosomal proteins are synthesized in the cytoplasm. The ribosomal proteins are transported from the cytoplasm into the nucleolus. Assembly of ribosomal proteins and ribosomal RNAs to make ribosomal subunits occur inside the nucleolus which then enters cytoplasm to carry out protein synthesis.

Answer:

The correct answer will be- homologous structures

Explanation:

The history of how life has survived on the earth can be studied through a field of biology called evolutionary biology.

The structures in organisms which are similar in their structure are thought to have derived from a common ancestor and are known as "homologous structures. "

Thus, homologous structures are the correct answer.
