Complete the following statements. At resting potential, the charge of the outside of the neuron is
and the inside is
.
The sodium-potassium pump helps maintain the resting potential.
The pump will move three
ions out of the cell while it moves two
ions into the cell.
Once a stimulus changes the membrane potential, the neuron conducts an impulse called a(n)
.
This causes the charge outside the cell to temporarily become
and
the inside to temporarily become
.
When the action potential arrives at the axon terminal it reaches a junction called the
Because the nerve impulse cannot cross the synaptic cleft,
are released.

The pea aphid, a type of insect, contains light-capturing pigments in its exoskeleton. pea aphids gained the ability to synthesize these pigments from genes transferred from fungi. while pea aphids do not have chloroplasts or fix carbon, researchers have found that pea aphids with more pigments have higher levels of atp than those with fewer pigments. pea aphids also have been shown to increase production of atp when exposed to sunlight. based on this information, is the pea aphid a true autotroph? a. yes, because the pea aphid can store energy from the sun in atp molecules. b. no, because the pea aphid is unable to use the energy from sunlight. c. yes, because the pea aphid does not need to use energy from food. d. no, because the pea aphid does not store energy from the sun as sugars.
