Species X is an endotherm that is adapted to hot desert weather so that it is able to function well in 120 degree F temperatures. Based on what you know about temperature regulation, which of the following adaptations might allow Species X to live in such a hot environment? A. Species X has more mitochondrial uncoupler proteins than cool-adapted species to help produce heat.
B. Species X has sensory neurons that are insensitive to temperature so it does not feel hot.
C. Species X does not internally regulate its body temperature so its body temperature is the same as its environment.
D. Species X has long thin ears to help dissipate heat.

D. Species X has long thin ears to help dissipate heat.

Explanation:

Endothermic (i.e., warm-blooded) animals often have developed a series of strategies or adaptations associated with heat dissipation with the aim of maintaining thermal balance and avoid water loss. One of these complex adaptations may be the presence of thin ears capable of increasing the surface area of the skin where the blood vessels pass, thus promoting the loss of heat and thereby acting like 'heat radiators'. For example, large thin ears in elephants increase the blood supply, thereby enabling them to lose excess heat in very hot weather.

igneous rocks which formed by the crystallization of magma at the surface of the earth called extrusive rocks. they are characterized by fine-grained textures because the rapid cooling at or near the surface did not provide enough time for large crystals to grow.
