If two species of bacteria use glucose as an electron donor but species A uses iron as the final electron acceptor and species B uses oxygen, then approximately how much glucose will species A need to maintain the same metabolic rate as species B?

the correct answer to your question would be option a

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
