Neurons produce an action potential at the same time or none at all
Answer: c) and b) are correct.
The brain is encased in a protective bony or cartilaginous housing in craniates.
The anterior end of the nerve cord is elaborated to form a brain in craniates.
Explanation: The craniates include the chordata with well-defined heads. This includes mammals, reptiles and fishes. So we can discard the other answers. Because most craniates have functional jaws, and the adults do not lose their chordate characteristics. The last one does not apply as a specific feature because the tunicate have neural crest but are not recognized as craniata.
(b) electrolytes are what sodium, chloride, and potassium in cells and body fluids are examples of.
When dissolved in water or bodily fluids, a substance called an electrolyte separates into ions (particles having electrical charges). The ions sodium, potassium, calcium, chloride, and phosphate are only a few examples.
The many electrolytes include sodium, calcium, potassium, chloride, phosphate, and magnesium. They come from the meals you consume and the liquids you drink.
Your body's electrolyte levels might get too high or too low. When your body's water balance changes, this may occur. The amount of water you consume and lose should be equal. If something throws off this equilibrium, you can be dehydrated or have too much water on your body (overhydration).
