Acertain type of bacteria is determined to have become resistant to antibiotics. in which method of genetic transfer did the bacterial cells most likely engage in order to transfer the antibiotic resistant gene to other cells.
binary fission
conjugation
diffusion
thermoregulation

When bacteria become resistant to overused antibiotics it means that  is not longer inhibited by the antibiotic at clinically achievable levels.  One way how these bacteria replicate and transfer the resistance is by engulfing cellular DNA by neighboring cells.Bacteria can take up naked DNA encoding for resistance native to similar species and incorporate it into their genome

Explanation:

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
