Answer:
Option (4).
Explanation:
Cell membrane potential may be defined as the difference in the electric potential between inside and outside of the cell. This potential is important for the action potential.
The resting membrane potential of the cell is -70mV. This membrane potential is maintained by the potassium ions of the cell. The cell membrane are almost 40 times more permeable to potassium ions than sodium ions and makes the cell membrane potential negative.
Thus, the correct answer is option (4).
For the answer to the question above, p<span>unctuated equilibrium (also called punctuated equilibria) is a theory in evolutionary biology which proposes that most species will exhibit little net evolutionary change for most of their geological history, remaining in an extended state called stasis. When significant evolutionary change occurs, the theory proposes that it is generally restricted to rare and rapid (on a geologic time scale) events of branching speciation called cladogenesis. Cladogenesis is the process by which a species splits into two distinct species, rather than one species gradually transforming into another.</span>
The correct option is RESILIENT.
The Alaskan forest usually undergo fire incident every year in order to enhance nutrient cycling of the ecosystem. Alaskan spruce is one of the plant find in the Alaskan forests and it is a very resilient plant, in that, when it is destroy by fire incident, it quickly grow back.
