The main purpose of a nociceptor is to respond to damage to the body by transmitting signals to the spinal cord and brain. There are two types of nociceptor: A delta fibres: activated by high threshold mechanoreceptors. thinly myelinated. Unmyelinated C-fibres: activated by polymodal nociceptors(PMN) and respond to intense mechanical stimulation, high temperatures and irritant chemicals.
es resultado de un fenómeno meteorológico que consiste en la precipitación de pequeños cristales de hielo.
Los cristales de nieve adoptan formas geométricas con características fractales y se agrupan en copos.Esta compuesta por pequeñas partículas ásperas y es un material granular.
Normalmente tiene una estructura abierta y suave, excepto cuando es comprimida por la presión externa.
La nieve es el vapor de agua que experimenta una alta deposición en la atmósfera a una temperatura menor a 0 °C y posteriormente cae sobre el suelo.

I would go with D as it is closest to correct. Every part of the surface of the Earth is a tectonic plate though. The plates vary in thickness, but all of the surface of the Earth is made up of tectonic plates, including the parts under the ocean. Technically, the Earth's landmass does not rest on the tectonic plates, it IS the tectonic plates, but it is the closest to correct here in my opinion.
