They are analogous organ because they have similar functions, but different evolutionary origins.
Closely resembling organs are the organs that are different physically in structure yet carry out a similar role. They are engaged with concurrent development.
Instances of Closely resembling Organs
Wings of Bats, Birds and Butterflies
This organ presents the three unique life forms that carry out a similar flying role however are different in structure. In birds, the wing structure is framed of bones covered with feathers. The wings of bugs are only the expansion of the integuments, which is the peripheral layer of any creature that safeguards the body. In bats, the wings are just the collapsed skin of their fingers.
Yam and Potato
These plant parts are only capacity types of starch and plant items, however physically, both are not the same as each other. Yam is a changed root that carries out the role of putting away starch for the plants. A potato is basically a changed stem that likewise carries out the role of putting away starch for the plant.

Answer:
Catalyst
Explanation:
Translation is the second process of gene expression which occurs in the ribosomes of living cells. The ribosome is a complex of Ribosomal RNA (rRNA) and proteins. Translation occurs when ribosomes attach to the transcribed mRNA molecule to read its codons using the transfer RNA (tRNA's) anticodon. The tRNA then carries amino acid that corresponds the codon it reads to the growing polypeptide chain.
In this process, amino acids are attached to one another forming a peptide bond. This linking of one amino acid to another is facilitated by rRNA's as it helps catalyzes the reaction like an enzyme. Ribosomal RNA catalyzes the reaction that forms a peptide bond between the amino acid in the A site of the ribosome and the growing polypeptide (future protein) in the P site.

1.golgi bodies
2. ribosomes
3.endoplasmic reticulum
4.lysosomes
Answer:Golgi apparatus, aka Golgi complex or Golgi body, membrane-bound organelle of a eukaryotic cells (cells with clearly defined nuclei) that are made up of a series of flattened, stacked pouches called cisternae. The Golgi apparatus is responsible for transporting, modifying, and packaging proteins and lipids to vesicles for delivery to sertain destinations that the nucleous picks. It is located in the cytoplasm near endoplasmic reticulum and close to the cell nucleus. While many types of cells contain only one or several Golgi apparatus, plant cells can contain hundreds.
Ribosomes are macromolecular machines, found in all living cells, that perform biological protein synthesis. Ribosomes link amino acids together in the order specified by the codons of messenger RNA and mRNA molecules to form polypeptide chains. Ribosomes consist of two major components: the small and large ribosomal subunits. Each subunit consists of one or more ribosomal RNA rRNA molecules and many ribosomal proteins . The ribosomes along with associated molecules aka translational apparatus.
The endoplasmic reticulum is a type of organelle made up of two subunits – rough endoplasmic reticulum , and smooth endoplasmic reticulum . The endoplasmic reticulum is found in most eukaryotic cells and forms an interconnected network of flattened, membrane-enclosed sacs known as cisternae ), and tubular structures in the . The membranes of the endoplamic retiulum are continuous with the outer nuclear membrane. The endoplasmic reticulum is not found in red blood cells, or spermatozoa. It is, in essence, the transportation system of the eukaryotic cell, and has many other important functions such as protein folding.
The two types of ER share many of the same proteins and engage in certain common activities such as synthesis of certain lipids and cholesterol. Different types of cells contain different numbers of the two types of ER depending on the activities of the cell.
The outer face of the rough endoplasmic reticulum is studded with ribosomes that are the sites of protein synthesis. The rough endoplasmic reticulum is especially prominent in cells such as hepatocytes but, smooth endoplasmic reticulum has little ribosomes and works in lipid synthesis but not metabolism, the production of steroid hormones, and detoxification,also smooth endoplasmic reticulum is especially abundant in mammalian liver and gonad cells.
Lysosome, subcellular organelle that is found in nearly all types of eukaryotic cells and that is responsible for the digestion of macromolecules, old cell parts, and microorganisms. Each lysosome is covered by a membrane that maintains an acidic environment within the interior the proton pump. Lysosomes contain a wide variety of hydrolytic enzymes that can break down macromolecules such as nucleic acids, proteins, and polysaccharides. These enzymes only work in the lysosome’s acidic interior; their acid-dependent activity protects the cell from self-degradation in case of lysosomal leakage or rupture, since the pH of the cell is neutral to slightly alkaline. Lysosomes were discovered by Belgian cytologist Christian René de Duve in the 1950s.
