So the question is asking on which of the following choices are the reason why the Indus Valley civilization decline and base on my research, I would say that the answers would be A. The surrounding land was severely deforested , C. Irrigation made the soil salty and unfit for farming and D. <span>Disease reduced the population. I hope this would help </span>
The answer is Eukaryote that is the sea spiders' domain
Due to the lack of the choices, let me just give you here the definitions of appositional and interstitial growth.
Appositional growth happens when the inner layers of the cell divides into chondroblasts, increasing the cartilage mass.
Interstitial growth happens when the chondroblasts in the cartilage divide to form new small groups of cells.
