(25 ) sending information to the hippocampus allows your brain to a) get did of the old information it no longer needs. b) make more connections to create more memory c) send messages to the neurons when the brain is full. d) try something new and relieve any stress you may have.

Since the hippocampus' involvement with the brain is to do with memories, I would go with B.) The Hippocampus acts as a "memory index" of sorts, and if you send information to it, it would make connections to, in a sense, help remember it.

it is b

Explanation:

answer: option c. i.e. electric current flowing “downhill” from the negative electrode to the positive electrode in a battery

explanation:

the water analogy to the circuits define the pipes (water flows) to the electric current. now, we know that the electric current flows from the positive terminal to the circuit (as shown in the diagram attached).

hence, option c is the correct answer.
