Accepted Answer. The Dragon Scale can be found on wild Horsea, Seadra, Dratini, and Dragonair. The only hitch to your plan is that you can only find them after getting the National Dex and Dratini and Dragonair can only be found by using the Super Rod, behind the Waterfall, at Mt. Coronet.
Microtubules are conveyer belts inside the cells. They move vesicles, granules, organelles like mitochondria, and chromosomes via special attachment proteins. They also serve a cytoskeletal role. Structurally, they are linear polymers of tubulin which is a globular protein.
Flagella help cellular bodies, such as sperm and bacteria, move through liquid. Flagella, like cilia, are composed of microtubules that are connected to the plasma membrane. The microtubules in a flagellum are grouped into nine pairs surrounding a pair of microtubules. The motion of flagella is a result of the microtubules sliding against each other. The filament, located at the end of the flagellum, is attached to the hook and is composed of flagellin.
