Below are the choices:
<span>the universe stays at a steady state
any physical laws are the same for the entire universe
the universe is going to eventually collapse
the universe is cooling down
</span>

Answer: The correct answer is- Starfish.
Radial symmetry depicts a body plan of an organism, which can be divided into two equal halves when a plane from any angle passes through central axis of the body.
Starfish is radially symmetrical organism as any plane can divide its body into two equal halves.
On the contrary, flatworm, butterfly, and tadpole show bilateral symmetry ( only single axis/ plane can divide the body into two equal halves.
The lithosphere is made up of the crust and the upper mantle so the answer is the first choice. crust and outer part of the mantle
It would be convection because it isnt having any physical collision which rules out conduction and it is going through mid air which rules out evaporation and radiation
