I’m desperate pls Neurons, by some estimates, spend up to 40% of their energy maintaining a resting membrane potential of
about -70 mV. Why is this a worthwhile investment? What would be the impact on our behavior if the
resting membrane potential was shifted either more negative, to about -90 mV, or more positive, to about
-65 mV? (Assume that everything else about the neuron, including threshold, remains unchanged).

Fruit bats in central america eat bananas and other fruits. banana plants rely on bats for pollination. what would be the most likely consequence on the banana crop if fruit bats were eliminated from the area? the banana crop would increase because bats would stop eating the crops. the banana crop would decrease because bats would no longer pollinate the crops. the banana crop would remain constant because bees would replace the bats. the banana crop would remain constant because the plants would adapt using asexual reproduction.
