Why whitefish embryo cells and root-tip cells are used to study mitosis instead of cells in a human bone or plant life?

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

i believe it is c: genes for body color and wing size are inherited separately from each parent.
