This is true.
Facilitated diffusion is a process by which molecules are transported across the plasma membrane with the help of membrane proteins.
It is a type of passive transport in which no energy from the cell is required for the process because a concentration gradient exists that allows movement of particles without expending cellular energy.
Materials diffuse across the cell membrane with the help of membrane proteins some of which are known as carrier proteins.
Membrane proteins are proteins that are attached to, or associated with the membrane of a cell or an organelle.
Answer: b) skraplanie
Explanation:
As part of the hydrological cycle, water is evaporated off of the surface of the earth and turns into the gaseous form of water which is water vapor. With temperatures getting colder as you go higher, the water vapor will begin to condense into water droplets in the process called Condensation.
As this happens, the water droplets will come together and begin to form clouds. This will continue till the cloud gets too heavy for the capacity of the atmosphere and will then fall as rain.
Active transport requires energy. Passive transport does not require energy. In case you did not know active transport is the movement of ions or molecules across a cellular membrane from a lower to a higher concentration.
