Small hive beetles, a pest of honey bee hives, must pupate in moist soil as part of their life cycle. a beekeeper placing his hives in full sunlight to reduce this pest by keeping the soil surrounding the hives drier would be an example of what type of control measure? biological/chemical/physical/mechan ical/cultural

is it multiple choice?

a ratio derived from the equality between two different units that can be used to convert from one unit to the other. information obtained from experiments, sometimes called experimental results. the part of the experiment that is affected by the independent variable.

energy per photon is e = h*c / λ  

e = 6.63*10^-34 * 3*10^8 / 6*10^-7 j = 3.315*10^-19 j  

nr. of photons = 10j / 3.315*10 = ^-19 j per photon = 3.02*10^19 photons
