| 1. | Adhering junctions facilitate the cells to communicate with each other. |
| 2. | Tight junctions help to stop substances from leaking across a tissue. |
| 3. | Tight junctions help to perform cementing to keep neighbouring cells together. |
| 4. | Gap junctions help to create gap between the cells and tissues. |
| Statement I: | The ground substance of bone is solid, pliable and resists compression. |
| Statement II: | The bone marrow of all bones is the site of production of blood cells. |
