Answer 30

true

Question 31

How does creating multiple neural pathways protect against memory loss and cognitive decline?

Answer 31

It allows for more ways to connect things and less of a risk of forgetting if there are multiple connections. If a bunch of synapses are damaged but 1, you still have that one connection

Question 32

What type of memory is this? You know that Joseph Robinette Biden Jr. is the 46th president of the United States.
