Answer:
Mid-ocean ridges are found in the sea floor at divergent boundaries because both plates are moving away from each other creating the opening for the lava to sleep up. Mid-ocean ridges are where sea floor spreading occur by lava seeping up to the surface of the opening and cooling therefore forming new ground and pushing older layers of ground further away.
Answer:
Pepsinogen is produced by chief cells and is activated by hydrochloric acid secreted by parietal cells.
Explanation:
Pepsinogen is a proenzyme produced in the chief cells (that are located in the stomach lining) that, when gets activated, is transformed into pepsin - a peptidase with the function to degrade proteins into amino acids.
The reason why pepsinogen is released inactive is that it would break down all of the cell's proteins because of its proteolytic nature. For this reason, it is released as a proenzyme and gets activated when reaches the acidic environment provided by the hydrochloric acid secreted by the parietal cells, also in the stomach lining.
