Answer:

a thick, mucous secretion and active mitosis of epithelial cells

Explanation:

The mucous neck cells of gastric glands serve to secrete mucus. Mucus is a thick sticky secretion that is rich in protein and carbohydrates. Apart from lubricating the stomach lining, its layer serves to protect the cells of the stomach lining from HCl.

To maintain the integrity of the stomach lining, the wore out cells are replaced by the new cells. To serve the purpose, the epithelial cells of stomach lining undergo mitosis and produce new cells to replace the damaged cells.

9. You find a rock 7,500 km away from the nearest seafloor spreading center. The plate is spreading at 5 cm/year, how old is the
Anna [14]
The answer is 150,000,000 years (150 million years)

Let's first convert 7,500 km to cm:
1 km = 100,000 cm
7,500 km = 7,500 · 1 km = 7,500 · 100,000 cm = 750,000,000 cm

Now, it is known that the plate is spreading at 5 cm per 1 year. Make a proportion:
5 cm : 1 year = 750,000,000 cm : x
x = 750,000,000 cm · 1 year ÷ 5 cm = 150,000,000 years
