Answer:a stationary front.
Explanation:
they allow repeated thunderstorms to move across the same area.
Answer:
Sub-threshold
Explanation:
If the stimulus is too small to generate the action potential, it is considered as subthreshold stimulus. Subthreshold stimulus causes the opening of small number of sodium channel i.e. not enough to generate action potential because action potential is generated by complete reversal of membrane polarity. Slight depolarization is caused by subthreshold stimulus by the opening of inadequate number of sodium channel but its magnitude is not enough to reach the threshold voltage. Consequently the action potential is not generated.
The response produced by subthreshold stimulus is called as local response or local depolarization because it could not travel further. The minimum stimulus required to generate the action potential is call as threshold stimulus and stimulus greater than threshold stimulus is called as suprathreshold stimulus. It changes the frequency of generated action potential.
I believe the correct answer is natural selection.
Natural competition and the fight for “survival of the fittest” is what pushes diversity the most.
1,560,000 milliseconds is 26 minutes and 26 minutes is about .43 hr
so the second one is the correct answer
Selective permeable means it selects what goes out and comes into the cell. If the cell membrane wasnt selective then things could enter the cell and destroy it.
