The most common isotope of carbon contains a nucleus with 6 protons and 6 neutrons. Suppose you have a beaker containing 6 grams of pure carbon. Approximately how many moles of carbon are present in the beaker? Eukaryotic cells move when their flagella or cilia bend. How does the bending of these structures occur? A) The Golgi apparatus transports numerous vesicles to these structures, making them bulge. B) Actin filaments are bound by the motor protein myosin. C) The motor protein dynein chan...

kinesin correct answers + directed motor protein Dynein correct answers - directed motor protein where is kinesin synthesized? correct answers cytoplasm (slow transport) where dynein synthesized? correct answers RER (fast transport) Schwann cells correct answers myelinating cells of the PNS - myelinates one axon - able to repair themselves if severed Oligodendrocyes correct answers myelinating cells of the CNS - myelinates many axons - unable to repair themselves Astrocytes...
