Hi, you've asked an incomplete question. Here's the missing passage reads:
"Honeybees play an important role in agriculture, by pollinating at least 90 different species of food plants, worth about 15 billion dollars in the U.S. alone. As a result, beekeeping or apiculture is a multi-million dollar business. However, over the last year, honey bee populations are crashing (Colony Collapse Disorder) with hives dying off in less than a week, without an obvious cause. Ian Lipkin a senior researcher in the Epidemiology (infectious disease) Department of Columbia University's Mailman School of Public Health believed the cause to be a pathogen (virus, bacteria, or fungus) of some sort. Use the information given to answer the following questions."
Design an experiment to test this hypothesis:
Need to remember, when we say experiment it basically means a scientific procedure carried out to test a hypothesis. While the word hypothesis refers to a question or assumption to be tested.
Hence, an experiment could involve selecting few groups of honeybees in the same location with the purpose of exposing each individual group to pathogens and different viruses and bacteria in other to observe if there are any trends.
Predict what the results will be if they support the experiment: In this case, a particular set of bees exposed to one of the viruses or pathogens should die faster than the other groups.
