Answer:
The neurons interact with each other at synapse through action potential generated in response to the stimulus. At the resting phase, all the ion channels remain closed and the cell maintains a high amount of Na⁺ ions outside the cell and a high amount of K⁺ ions inside the cell. This difference maintains the membrane potential at -70mv.
When a stimulus activates a cell receptor, it causes the opening of the sodium channels in response to either mechanical stimulus or neurotransmitter released due to stimulus. The opening of the sodium channels leads to the influx of Na⁺ ions which changes the potential from -70 mv to more positive value. When this change in membrane potential reaches - 55 mv it leads to the opening of the voltage-gated channels which causes an influx of Na⁺ ions. This more influx of Na⁺ ions leads to depolarization when the membrane reaches above the threshold and the action potential is generated in the neuron.
B. Energy is needed for both reactions

Evolution; one organism adapting to better survive new conditions.
Answer:
Willa's Continuous use or high dose of aspirin can lead higher risk of blood vessel closure in her developing foetus it can also lead to increased risk of bleeding in the brain
Explanation:
Although low dose of aspirin can be used during pregnancy to prevent or delay onset of preeclampsia, high dose or continuous use of it is not advised during pregnancy
