Unit Test Which title best fits Rahma's notes? Rahma took these notes on a process involving the movement of molecules, but she forgot to title them. O Active Transport in Cells -Causes molecules to move until they are evenly distributed -Moves from high concentration to low concentration -Has no need for added energy -Can occur with or without a membrane being present O Passive Transport in Cells O Osmosis O Diffusion

passive transport

Explanation

he simplest forms of transport across a membrane are passive. Passive transport does not require the cell to expend any energy and involves a substance diffusing down its concentration gradient across a membrane.

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.
