Which term refers to the movement of materials through a cell membrane without using the cells energy

Answer;

Passive transport

Explanation;The movement of materials across the cell membrane without using cellular energy is called passive transport. On the other hand the energy-requiring movement of molecules across a membrane from a region of lower concentration to a region of higher concentration is called the active transport.It includes processes such as osmosis. diffusion and facilitated diffusion.Diffusion is the movement of dissolved molecules in a fluid or gas from a region of higher concentration to a region of lower concentration.Osmosis is the diffusion of water molecules across a semipermeable membrane from an area of higher water concentration to an area of lower water concentration.Facilitated diffusion is a type of diffusion of molecules assisted by protein channels that pierce a cell membrane.

The independent variable is the type of music.the dependent variable is the pulse rate.the intervening variable is the age of the subject.if the mother does not like rock, her pulse is likely to not increase.the same might be true for the sister.the friend may like rap and gets excited.to establish cause/effect relationship, all of the subjects must be consistent.hope i .

The answer should be vaporization
