Answer:

Action potential.

Explanation:

Action potential may be defined as the change of the membrane potential of the cell with response to the stimulus. The different ions enter and exit the cells.

Action potential generates in the cell when the threshold voltage - gated channel reaches and opens the voltage gate channel. The opening of voltage gated channel changes the membrane potential of the cell.

Thus, the correct answer is option (4).

What do the different colors of visible light represent?
dybincka [34]

The right answer is Wavelengths of energy.

White light is made up of all colors. The rainbow is actually the decomposition of white light by droplets of water like a prism.

Each color corresponds to an electromagnetic radiation of particular frequency and wavelength.

The sensitivity of the eye is maximum around 550 nm, in the yellow-green. The spectrum of visible light ranges from 400 to 780 nm but its perception depends on each individual (tastes and colors ...).

How do axial filaments differ from regular bacterial flagella? How do axial filaments differ from regular bacterial flagella? Th
aksik [14]

Answer:

The axial filament is located between the cell membrane and the outer membrane.

Explanation:

Axial filaments are structures used for motility too. They wraped around the cell body and are found in spyrochetes. The origin of the flagella is in the periplasmic space, the space between the inner membrane and the outer membrane they differ because other flagellum are near the cell surface, attached to the basal body enclosed in the cell envelope.
