When the biceps brachii contracts, the lower arm extends. a. true b. false?

The answer is FALSE. The biceps muscle is located in the inner portion of the upper arm while the triceps muscle is located at the outer portion of the arm. To straighten your arm again, you relax the biceps brachii and contract the triceps brachii. Contracting the biceps makes the elbows bend

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.
