How technical of an answer do you want? The resistance of any fuse in any circuit should be negligible. If it is not, the circuit or the fuse is poorly designed. Of course there is resistance in the fuse which actually does matter, or else it would be able to handle an infinite amount of current without blowing from excess heat (I^2R losses). In circuits where very small resistances matter, there are other ways to deal with over current issues.
The 13 amp fuse with blow at the lower rate to the 15 amp fuse. And At 15 amp the motor is normally more powerful - check the wattage used in both
No, you could overload the wiring and start a fire.

The purpose of a fuse it to protect the wire that goes to the load. A 15 amp fuse protects a #14 gauge wire. A 20 amp fuse protects a #12 gauge wire. To answer your question if the wire size is #12 coming from the 15 amp fuse now then it can be upped to 20 amp fuse. If it isn't then you are taking the risk of overloading the #14 wire with a 20 amp fuse. This can lead to insulation failure of the #14 wire, overheating with the possible outcome of a fire breaking out somewhere in the circuit.
Most branch circuits in kitchens are either 15 or 20 amp. if in doubt use the lower (15) amp fuse.
