The correct answer is option C, that is, from negative to positive.  

Action potentials are those electrical impulses, which transmit signals around the body and are nothing more than a temporary shift, that is, from negative to positive in the neuron's membrane potential resulting due to the flowing of ions in and out of the neuron suddenly.  

During the resting state, that is, prior to an action potential, all of the gated potassium and sodium channels are closed. They open once an action potential has been initiated. The sodium channel opens and more sodium ions move within the cell, making the charge more positive.

sleet_krkn [62]

In the dark, an object is more clearly seen when viewed in peripheral vision than when viewed directly, this phenomenon occurs because the rods located in the retina are:<u> more </u><u>sensitive</u><u> in the dark than </u><u>cones</u>.

The retina extends through the posterior portion of the eyeball is the innermost layer and in it are the photoreceptors: cones and rods.

Rods and cones are the two types of photoreceptor cells in vertebrates that capture light energy (photons) and convert it into electrical signals.

  • The rods are sensitive to changes in light, since their detection thresholds are low, so they only come into operation when the light intensity is low (scotopic vision or night vision).

  • Scotopic vision has relatively low acuity, as the details of an object cannot be discerned or its color appreciated.

  • On the contrary, cones have a much higher threshold for light, they are responsible for daytime vision (photopic vision) and their mission is to detect colors and shapes (details).

Therefore, we can conclude that in the dark, an object is more clearly seen when viewed in peripheral vision than when viewed directly, this phenomenon occurs because the rods located in the retina are: more sensitive in the dark.

How long does it take for chicken and dumplings to spoil?
dezoksy [38]

Well, the technical rule of thumb would be that if it is raw, it has about a good 2-3 days before it goes bad. If it's cooked, it has about 3-4 days before it spoils. If they are leftovers, you have, at the latest, a total of 4 days before they aren't "safe" to eat anymore. Hope this helps!
