Geiger-Muller tube is instruments requires you test three times the background of the work area.
<u>Explanation</u>:
These detectors are gas filled detectors and hence requires time for responding to the value. This time is taken because during this period it collects the electric charges and features of the electric circuit. It also gets stabilized during this period. This device has thumb rule i.e one must wait or hold for at the least 3 times the time constant before getting the precise and accurate reading. The time constant order is 10 seconds for the ionization chamber but for the Geiger counter it can vary from seconds to greater than 20 seconds

Answer:
The flowers and moths experienced the same allopatric speciation events during their history.
Explanation:
Co evolution may be defined as the process of the evolution of more than two species together that oppositely affects the evolution of each other. The natural selection provides the base for the co-evolution.
The co evolution generally occurs in the flowers and its pollinating species. The moth and the flower speciation represents the co evolution because both evolution are affected by each other. They have experienced the co evolution due to the allopatric speciation event and leads to teh genereation of the specific change in the characteristics.
Thus, the correct answer is option (e).
