quiizlet A friend of yours has gone out on a warm day for a relatively long jog. She has taken along water to drink. After about an hour the water is gone, but your friend continues on for another 30 minutes. The entire time your friend has been running, she is also sweating. Her activity has caused a loss of electrolytes, and altered ion concentrations in the fluid surrounding cells. + Consider your friend's current reduced level of circulating K. How does it affect the resting membrane potential compared to normal K + levels? A. Resting membrane potential is less negative than normal. B. Resting membrane potential is more negative than normal. C. Resting membrane potential will be the same as normal.

Jayla Navarro · Answer 1

The correct statement is -

B. The resting membrane potential is more negative than the normal.

Explanation:

According to the question,

That person was out of the water 30 minutes before but she continued her running which let her sweat more.

More sweating will cause more loss of electrolytes. Less water and electrolytes will lower the threshold level of the Resting Membrane Potential. Excessive loss of water and electrolytes will lower the threshold level of Resting Membrane Potential more than normal.
