In vertebrates, the speed of transmission along neurons is much faster in myelinated neurons compared to unmyelinated neurons.
which of the following is not true of transmission along myelinated neurons?

a. sodium and potassium channels are concentrated at nodes of ranvier
b. saltatory conduction in non-myelinated neurons slows the process of transmission
c. action potentials are generated only in the nodes of ranvier

How are the tortoises that darwin observed on the galápagos islands similar to the anoles that losos studied

Which experiment would most likely contain experimental bias ?

Juan and carol were studying invertebrates in biology. they knew that segmented or earth worms preferred a dark, moist habitat. during this lab, they would be investigating the responses of organisms called planaria or dugesia tigrina. these were simple flatworms that still had a one-way digestive system and a very simple nervous system. juan and carol placed the planaria in a petri dish containing cool, distilled water that was partially covered with black paper. they shined a light on the dish. next, they removed the paper and placed a small amount of chicken liver at one end of the dish. they added a few large salt crystals to the water. finally, they added drops of hot water to the cool water in the petri dish. their results can be seen in the data table. according to their experiment, all but one conclusion is valid.
