Answer:
Option (3).
Explanation:
The action potential may be defined as the change in the electric potential of the cell that helps in the propagation of the nerve impulse. The resting membrane potential of the cell is -70mV.
Threshold potential may be defined as the minimum potential required to transmit the nerve impulse. If the difference between the excitatory signal and inhibitory signal exceeds the minimum intensity, known as threshold. The propagation of nerve impulse occurs.
Thus, the correct answer is option (3).
Answer: Molarity
Explanation:
Molarity: Is defined as moles of solute/liter of solution.
Molality: Is defined as moles of solute/ mass of solvent.
So if the number of moles is the same considering the total amount of solution, then the molarity would be the same.
Mass and distance
mark me brainliest!!!!!
The cosmological principle makes assumptions that provide scientific guidelines to enable its study.
Answer:
D. 6 CO 2 , 6 H 2O , and sunlight
Explanation:
The reactant are the substances are going under a reaction. They are the "items" needed for a product to form. In which in this case, 6 CO 2 , 6 H 2O , and sunlight are needed to make C 6H 12O 6 + 6 O 2
