Answer:
<h2>Endoplasmic reticulum</h2>
The endoplasmic reticulum is a network of membranes within the cell through which proteins and other molecules move. Proteins assemble into organelles called ribosomes. When proteins are destined to be part of the cell membrane or exported out of the cell, ribosomes assemble them and add them to the endoplasmic reticulum, giving it a rough appearance.

<h2>MEXICO ♥</h2>
RNA is most commonly if not almost exclusively found in thr cytoplasm of the cell.
Answer:
Explanation:
The energy driving the movement of molecules during passive transport comes from differences in the concentration of the molecules on either side of the membrane with the molecules tending to move from the side of higher concentration to the side of lower concentration because of their net thermal movement.
Because there are two major ways that molecules can be moved across a membrane, and the distinction has to do with whether or not cell energy is used. Passive mechanisms like diffusion use no energy, while active transport requires energy to get done
How is energy used to move?
Molecules do not stop moving once they reach equilibrium. Passive Transport (no energy needed). The movement of particles from an area of high concentration to low concentration. Particles pass right through the cell membrane. the (passive) movement of large particles or substances across the cell membrane through protein channels.

Answer:
D) Tight junctions
Explanation:
Based on the information provided within the question it can be said that the structure that performs this function are known as tight junctions. This structure has two different functions. The first being to limit the passage of molecules and ions through the space between cells, and the second function is that is blocks the movement of important membrane proteins between the epithelial cells
