Answer:
The correct answer will be option-E
Explanation:
The neuron is the functional unit of the nervous system which transmits the signals to and fro the tissue and nervous system. The neurons transmit the signals in the form of an electrical impulse as a result of the movement of the ions across the neuron.
When a neuron does not transmit any signal therefore it is known to be at rest but at rest, the movement of ions takes place but very slowly. The movement ions lead to the accumulation of sodium ions inside than outside whereas potassium ions are concentrated outside as compared to inner.
This charge difference leads to the disequilibrium in the charges and hence a potential gradient is created. This potential is known as resting potential.
Thus, option-E is the correct answer.

Answer:
Acclimatization
Explanation:
Acclimatization is the change in the body of an organism in response to changes in the environment to maintain equilibrium (homeostasis). In the case of the salmon, when the environment changes from fresh to salt water and back, the chemical homeostasis would be altered if the fish didn't adjust. The adjustments in the fish gills are the response of the fish to acclimatize to the changes in the chemical environment in order to maintain homeostasis.
Answer:
The most important reason for learning about environmental systems is due to the fact that we should know what's going on in the world around us. If we were to travel to Asia, we should know the forests that lie there to pack appropriately. It's also important to just be aware of how the world works. It's also good to know what rock type you'll be walking on, so you can pack shoes accordingly. Overall, it's better to know the world around you than to live in ignorance.
