Answer: It is True species richness grows twoards the poles
Answer:
Option (2).
Explanation:
The cell potential or membrane potential may be defined as the difference in the electric potential between inside and outside of the cell. The membrane potential of the cell changes during the propagation of action potential.
The resting membrane potential is -70mV. The influx of sodium ions causes the depolarization of the cell membrane. The cell potential changes from -70mV to + 30mV. The membrane potential becomes more positive during the depolarization phase.
Thus, the correct answer is option (2).
Answer:
Option A, Competition has restricted the ranges of both species
Explanation:
When two species which depend on the exactly same kind of resources, get into a mode where they prefer to stay in two different ecosystems without interfering each other’s circle and thus they get excluded from each other due to competition. This phenomenon of the ecosystem is called Competitive exclusion
According to Gause's Law of competitive exclusion two species which are competing for similar kind of resources are unable to stay together.
Hence, option A is the correct choice.
