Answer:
Think of the open-source project Nextstrain.org as an outbreak museum. Labs around the world contribute genetic sequences of viruses collected from patients, and Nextstrain uses that data to paint the evolution of epidemics through global maps and phylogenetic charts, the family trees for viruses.

Answer:
The digitization of performance management not only provides more precise data but also positively influences management processes and strategic development. Technology-enabled performance management tools simplify the manager's evaluation process and turn employees into active participants in their review sessions
Answer:
A) $18.36
B) $10.24
Explanation:
Heat supplied Q = 24000 kJ/h
J/s = watt
I hour = 3600 sec, therefore 24000 kJ/hr becomes 24000/3600 = 6.67 kW
Coefficient of performance of heating for heat pump is
COP = T2/(T2 - T1)
T2 (hot temperature) = 20 °C
T1 (cold temperature) = -7 °C
COP = 20/(20 - (-7)) = 20/27 = 0.741
Also COP = Q/W
where W is the power input to the heat pump
0.741 = 6.67/W
W = 9 kW
Operating for one day is 24 hr
Therefore heat pump uses 9 x 24 = 216 kWh
Cost per day = ¢8.5 x 216 = ¢1836 = $18.36
For ground at 5°C
COP = 20/(20-5) = 20/15 = 1.33
1.33 = 6.67/W
W = 5.02 kW
For 24 hr it becomes 24 x 5.02 = 120.48 kWh
Cost = 8.5 x 120.48 = ¢1024.08 = $10.24
To convert a decimal integer number (a decimal number in which any fractional part is ignored) to any other radix, all that is needed is to continually divide the number by its radix, and with each division, write down the remainder. When read from bottom to top, the remainder will be the converted result.
hope this helps
