What direction foes the electrical signal travel through the neuron?

• From dendrites, down the Axon, and out Axon terminalsThis is a correct answer

• From Axon terminals, down the Axon, & out of the dendrites

• Any direction up or down the cell

• From the Axon, to the Dendrites, and out the Axon terminals

What does high concentration of IAA do in the shoot of plants?

• promote cell elongation

• inhibit cell elongation

• promote cell division

• inhibit cell division

What does high concentration of IAA do in the root of plants?

• promote cell elongation

• inhibit cell elongation

• promote cell division

• inhibit cell division

How does IAA move in a plant shoot

• diffusion

• active transport

• osmosis

• endocytosis
