You cant find a nucleus in bacteria you see under a microscope. why?
a. they are prokaryotic cells
b. they are eukaryotic cells
c. your not looking hard enough
d. both b and c

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 would cause an increase of percipitation, though i could be wrong. so i would say b is the answer.
