Some cells, like mature nerve cells or muscle cells, do not divide. other cells will divide only when the cellular environment signals that it is necessary. according to model 1, what "phase" of the cell cycle are these cells said to be in when they are not dividing or planning to divide?

Synthesis is when they are not dividing

the transfer for conduction is the heat transfering from the liquid to the spoon

the transfer for convection is the heat rising from the liquid to the air

the transfer for radiation is the heat going through the sides of the cup and to the air

at least that is what i would do
