Answer:
active transport
Explanation:
they are using energy to move across the membrane, using energy means its active Hope this helps
Answer:
dark blue: denser oceanic crust is subducting...
Explanation:
Controls what enters and leaves the cell
Answer:
True, by active transport
Explanation:
The influx and efflux of molecules through the cell membrane depend on the concentration gradient.
When the molecules down their concentration gradient that is from higher concentration to lower concentration are known as passive transport but sometimes the cell has to transport the ions against the concentration gradient.
When the ions move against the concentration gradient, they use energy in the form of ATP molecules and then transport the ions. This is known as active transport.
In the given question, since the sodium ions move inside the cell against the concentration gradient by the active transport.
