The cytoplasm of a certain cell, such as a neuron, already has a high concentration of K ions. How can K ions continue to enter the cell and continue to increase in concentration

The question is incomplete as it does not have the options which are:

A. endocytosis

B. active transport

C. facilitated diffusion

D. infusion

E. osmosis

B. active transport

Explanation:

The neuron cell involves the influx and efflux of the sodium and potassium ions. These ions move through membrane proteins by facilitated diffusion and active transport.

The active transport allows the movement of ions against the concentration gradient that is even if the concentration of ions is higher.

In the given question, although the potassium ions are higher in the cytoplasm of the neuron, the potassium ions can enter the cell through active transport.

Thus, active transport  is correct.

hi there!

answer: b. nucleolus

explanation: nucleolus is a structure in the nucleus are ribosomes are made.

hope this you!

have a nice day! : )
