Answer: the four terrestrial planets must once have been hot enough to be molten (like a liquid)
Explanation: Terrestrial planets can be defined as any planet of the solar system or any exoplanet which is "Earth-like" in the sense that it is composed primarily of metals and rock, in contrast to a planet which is a gas giant.
Within the Solar System, the terrestrial planets are the inner planets closest to the Sun, i.e. Mercury, Venus, Earth, and Mars.
Scientist believing that the densest, heaviest materials are at the center and not evenly distributed can be due to the fact that they must once have been hot enough to be molten. In this case, density will take place, making the heavier under and the lighter on top.
Answer:
b) the tendency to return to a balanced or stable internal state
Explanation:
Homeostatis is the state of an organism's internal biology which is steady and is maintained by the organism. It is the base state of an organism.
The organism maintains homoestasis by three components a receptor, a control centre, and an effector. The receptor senses any change in the enviroment, the control center acts according to the environment and the effector causes a change in the organism to reach homeostasis.
