The average of the following set of measurements is 20°C.
To find the average of the given set of measurements
Given: 
Set of measurements = 27°C, 12°C, 31°C, 19°C, 23°C, 11°C, 17°C
Number of Observations = 7
Average = Sum of observations/Total number of observations
Sum of observations = 27°C+12°C+31°C+19°C+23°C+11°C+17°C
= 140
Total number of observations = 7
Substitute the values in the formula
= 140/7 = 20°C
Therefore, the average of the following set of measurements is 20°C

"<span>The second part of the mitotic phase, during which cell division is completed by the physical separation of the cytoplasm components into two daughter cells is called telophase."
Telophase is the last phase of mitosis. The name itself indicates terminal (telo) phase. </span>The chromosomes get to the cell poles and nuclear membranes are formed around each set of chromatids. The actual cell division is called c<span>ytokinesis and it starts at the end of the telophase.</span>
