Question

a type of junction between cells that allows the passage of small molecules and ions from cell to cell is a ________. answer spot desmosome gap junction tight junction lumen i dont know yet

Explanation:

To solve this, we analyze each option:

• Spot desmosome: Anchors cells, not for molecule passage.
• Gap junction: Allows small molecules/ions between cells.
• Tight junction: Seals cells, prevents passage.
• Lumen: A cavity, not a cell junction.

So the correct option is gap junction.

Answer:

B. gap junction (assuming the second option is labeled B; if labels are different, adjust, but based on the list, the correct one is the "gap junction" option)
