The correct answer is option d, that is, leak channels.
The cell membrane comprises protein channels known as leak channels, which permits sodium and potassium ions to leak down their concentration gradients. The membranes of the cell are significantly more permeable to potassium ions in comparison to the sodium ions, due to the presence of more K+ leak channels than Na+ leaks channels.

Answer:
hertz (Hz); decibels (dB)
Explanation:
The Sound Measurement units are: Hertz (Hz) and Decibels (dB).
As you may know, sound travels in waves. The speed of the vibrations of these waves defines the tone of the sound. The tone is measured in Hertz, vibrations per second. The higher the number of vibrations per second the higher the sound. Hertz therefore measures the pitch of the sound. The decibel, in turn, measures the power of the sound, its energy, the stronger or weaker it is emitted. Measures the volume of the sound.
