Which of the following is not true about the cell membrane?

phospholipids are fluid and can move throughout the membrane.

carbohydrates are useful in cell communication.

protein receptors are found on the exterior of the cell only.

phospholipids heads are negative and attracted to water.

Phospholipids heads are negative and attracted to water.

Just so you know the “head” of a lipid present in your cell membrane is considered to be are referred to as hydrophilic meaning attracted to water were as the "tail" of the lipid is considered to be hydrophobic as you might of surmised meaning hating water I suppose.

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.

explanation:

it's c. (to reduce the greenhouse effect/carbon gasses)
