2 and 4 should be correct
The temperature of the plasma gasses cools. This is because the gases lose some of their energy into light photons that disperse into space. When the plasma gases get cooler gases to become denser and sink to the bottom of the convection zone and are replaced from upwelling hotter plasma gas. The temperature at the bottom of the convection zone is approximately 200,000° C while that at the surface is 5700° C.
Hello!
Natural selection is the way that animals evolve.
The theory of natural selection is that the animals that do not have a specific trait to survive in their environment will die. The animals that do have the trait will survive. The animals that survive will then pass the trait down to their offspring, who will also likely survive because they have the trait. This is how species evolve and continue to survive in their environment.
The species evolve because only the fittest survive (this is known as "survival of the fittest"). The animals that do not have the needed traits will die and they cannot have offspring.
I hope this helps answer your question! Have a great day!
Answer:
endothermic
Explanation:
The difference between an endothermic and exothermic reaction is that heat is released in an exothermic, while an endothermic involves absorbing energy from the surroundings. It is all in the prefixes exo and endo.
