The right answer is Schwann cells.
<span>Schwann cells, or neurolemmocytes, are peripheral glial cells. With oligodendrocytes, they make myelin sheaths around the axons of neurons, protecting them and increasing the speed of electric nerve impulses.</span>
it is a scientific theory because people haven't proven that it it 100% correct we do not know if it is hence the theory..........
Many poisonous and toxic animals are brightly coloured, and other animals and predators are instinctively wary of brightly coloured animals. This is called warning colouration or aposematism. Described more scientifically, these colouration adaptations are to deter predators by using a warning signal,<span> which indicates that consuming the prey item would be unprofitable</span>. Nudibranchs back up this warning by secreting poisons that would be toxic or foul-tasting to predators. Nudibranchs have developed this strategy probably because it has a lower energy cost compared to developing a protective shell.
That's because they are in the same climate zone. The earth's climate zones change going from the north pole to the equator, and then from the equator to Antarctica, like a mirror image. The two are found in the same zones on the opposite hemispheres.
