Mars has a diameter that is approximately half that of Earth. If the interiors of these planets are heated by radioactive decays, how does the heating rate of the interior of Mars compare to that of Earth? a. The heating rate of Mars is 0.125 times that of Earth. b. The heating rate of Mars is 8 times that of Earth. c. The heating rate of Mars is 0.5 times that of Earth. d. The heating rate of Mars is 4 times that of Earth. e. The heating rates are about the same.
Heating Rate Comparison The heating rate of a planet's interior due to radioactive decay is proportional to its volume, which is determined by its radius cubed. Since Mars has a diameter...

what happens to the surface area to volume ratio of a cell as the cell grows?
what happens to the sa:v ratio when a cell undergoes division?
As a cell grows bigger as its internal volume enlarges the cell membrane expands. The volume increases more rapidly than the surface area so the relative amount of surface area available to pass materials to a unit volume of the cell gets decreased.So as a...
