Answer;
-Flagellum (flagella; plural)
Explanation;
-Prokaryotes are single-celled organisms belonging to the domains Bacteria and Archaea.
-A flagellum is a whip-like structure that allows a cell to move. They are found in all three domains of the living world: bacteria, archaea, and eukaryota, also known as protists, plants, animals, and fungi.
-The primary role of the flagellum is locomotion, but it also often has function as a sensory organelle, being sensitive to chemicals and temperatures outside the cell. Flagella are organelles defined by function rather than structure. Flagella vary greatly. Both prokaryotic and eukaryotic flagella can be used for swimming but they differ greatly in protein composition, structure, and mechanism of propulsion.
Answer:
The statement is true.
Explanation:
The DNA structure had been studied for years, and there were even some theories, like the three-stranded DNA structure. Nevertheless, until Watson and Crick started to develop the actual structure of the DNA, with the help of Rosalind Franklin's pictures, there wasn't a strong theory that could explain some of the DNA properties.
