There is a population of beetles that typically have black wings. a scientist studying these beetles knows that their eggs hatch in early spring, the young insects grow through the late spring and summer, they lay eggs in the early fall, and they die in the early winter. recently some beetles have been born with white wings. early in life, the black- and white-winged beetles seem to be very similar in number of mating events, eggs laid, and survival rates, but shortly after laying their eggs the white beetles die and there are only black-winged beetles during the late fall. which of the following is a true statement about the beetles?
a. white and black winged beetles have equal fitnessb. black winged beetles have a higher fitness than white winged beetlesc. the number of baby white winged beetles will decrease in frequency over time. d. white wings are an adaptation

The answer is:

A. White and black winged beetles have equal fitness.

Both types of beetles have similar habits and acts, the only thing is that the white beetles die sooner. But since they still lay eggs before that and their babies will indeed hatch, the white beetles have an equal fitness to the black beetles. Hope that helps. :)

the transfer of energy between two molecules spaced just nanometers apart plays a key role in many technologies, including photovoltaics, quantum information systems, lighting, and sensors, as well as in biophysics to measure nanometer distances and in photosynthesis. but an open question in this area is what effect, if any, the surrounding photonic environment has on this nanoscale energy transfer. by designing and performing a carefully controlled experiment to answer this question, scientists have settled the debate and found clues to improving the efficiency of many of the technologies that rely on this process.
