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:
Over millenia, these rocks get pushed back into the Earth's mantle, and get pushed into a volcano heating it up and turning it into magma.
Explanation:

C - P waves move quickly and S waves move slowly through solids.
There are two known gene products, RNA and protein.
The regulation of gene expression is important because in different moments of human deveopment different substances are needed and also during the stable fase of human development (adulthood) necessities are dieverse.
The regulation of gene expression is what makes cells and an tissues different and that is why it's also so important.
This question is indeed not east. Hope I suplied enough information according to your needs (there is still way more info on the subject).
Hope it helped,
Happy homework/ study/ exam!
Hi there! The reason cells undergo mitosis is for cell repair and for growth. I hope this helps!
