Mutations of any different species of different backgrounds, will affect the growth of an animal. For instance an organisms DNA affects how it looks, behaves and its physiology. So the change in the organism's DNA can cause in all aspects of its life. A mutation itself is vital, or essential to evolving. Its a raw material of a genetic variation.
Answer:
-70 mV.
Explanation:
The membrane potential is important for the generation of action potential. This helps in the transmission of signals in the body and helps in the communication.
As the cells is in the resting membrane potential, Marcus recording shows the -70mV. The cells at the resting membrane potential has the membrane potential with -70mV. This potential is maintained due to the leaky voltage gated potassium channels.
Thus, the correct answer is -70mV.
It's more accurate, especially since heart rate is almost universally measures in beats-per-minute, than, say, timing your pulse for a [factor of 60] seconds (30 seconds, 20 seconds, 15 seconds, 12 seconds, etc.).
