Natural selection occurs to give help the best survival chance to the organisms.
The three ways that heat is transferred are as follows:
Conduction, convection, and radiation.
Radiation is when heat is transferred in waves. It is the only type of transfer that can occur in a vacuum, so that is how heat reaches earth from the sun.
Conduction is when heat is transferred between solid objects. That is how heat is transferred between objects on the earths surface.
Convetsion is when heat is transferred through a liquid. This is how the ocean heats all the way through, rather than just the surface.
The concentration of a liquid refers to how diluted or saturated the liquid is. This orange juice is so diluted it tastes like water.
It means wolf are begining to disseaper. They are going to be extinct.
