A: the molecules spread out and move more quickly
B: the temperature increases as the water molecules change from ice to vapor since it goes into the melting phase and then the condensation phase
Normally it’s the plasmodesmata that allows exchange of molecules between adjacent cells. But I’m still not sure if water is included!
The correct answer is option (A) the fossil record.
Coordinated stasis refers to the stasis or the no evolutionary changes in the organisms for millions of years, which is followed by extinction and formation of the new species.
Fossil records have the evidence of ecological and evolutionary stability in the species over a long period of geological time scale separated by intervals of abrupt change. The best example of this being the animals of the Middle Devonian Hamilton group. Thus, fossil record is the only source of record showing this long period of stasis and separated by periods of abrupt changes in the species due to environmental pressures.
