Bad White [126]

Answer:

True.

Explanation:

The interference theory explains the memory of the human brain. These memories are long term memories. Two main types of interference are proactive interference and retroactive interference.

The retroactive interference means when the older memories vanishes due to the learning of the new memory. The previously learned memories are forgotten by the individual. The same thing has happened with Mimi as she forgot the previous recipe due to the new memory.

If you pumped contaminated water from an aquifer, cleaned the water and pumped it back in what would happen?
SashulF [63]

Answer:

It’s impossible to know what would happen

Explanation:

If contaminated water is pumped form an aquifer, cleaned and pumped back, it would be impossible to know what would happen unless the source of the contaminant is known.

If the source of the contaminant is not known, it would be difficult to predict what would happen.
