I'm not 100% on this but this is what I came up with. A few examples of unicellular organisms include amoeba, bacteria, and paramecium. Another example is Eukaryotes which have a nucleus, and a more complex cell structure.
The start up temperature is 25 degrees and every 1 minute it increases by 10 degrees, in 5 minutes (10*5) equals 50degrees plus start up temperature of 25 degrees equals 75 degrees
