How has artificial selection made farmers more productive?
A. Artificial selection has given farmers an opportunity to
study science.
B. The crops and livestock are bigger and stronger, so they
provide more food per square foot of land.
C. Artificial selection has ruined farming because crops and
livestock have become sickly.

humans can cause extinction of a species through overharvesting, pollution, habitat destruction, introduction of invasive species (such as new predators and food competitors), overhunting, and other influences. explosive, unsustainable human population growth is an essential cause of the extinction crisis.

i didn't have the answer choices , but i tried my best.

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.
