Neural impulses are transmitted to bipolar cells when light energy enters the eye and triggers ________ in the rods and cones.
lana66690 [7]

Neural impulses are transmitted to bipolar cells when light energy enters the eye and triggers CHEMICAL CHANGES in the rods and cones. This process is known as phototransduction.

Phototransduction refers to the process by which photoreceptors convert light into electrical signals.

Photoreceptors (i.e., rod and cone cells) are specialized cells in the retina of the eye which are capable of converting light into electrical signals and thus trigger different physiological processes.

Phototransduction is triggered by the activation of signaling proteins, that open or close ion membrane channels in photoreceptor cells.

DNA samples are added into wells with the help of electric current.

<h3>How dna samples added to the wells?</h3>

DNA samples are added into wells at one end of a gel whereas an electric current is applied to pull them through the gel. DNA fragments are negatively charged, so they move towards the positive electrode.

So we can conclude that DNA samples are added into wells with the help of electric current.
