The sodium-potassium pump is involved in active transport that moves 3 sodium ions from the cell for every 2 potassium ions it m
Ugo [173]

Answer:

The sodium-potassium pump is an active transporter because it needs to move sodium and potassium ions against the concentration gradient.

Explanation:

You have to think of it as outside vs inside the cell.

Outside the cell, you have 5mM K and 150mM Na. Inside the cell, you have 100mM K and 10mM sodium. Without the transporter then the ions would go from greater concentration to lower concentration.  Energy keeps the ions going from the way they would naturally happen.

What is the shortest period in which a population of darwin's finches can evolve?
Studentka2010 [4]
Darwin's finches are a gathering of around fifteen types of passerine winged animals. They are outstanding for their exceptional decent variety in nose frame and capacity. They are regularly named the subfamily Geospizinae or tribe Geospizini. 
After an immense dry spell, the greater hooked finches lived and the littler ones passed on. So two years after the fact finches har mouths that were somewhat greater.
