B) Neurotransmitter attaches to receptors on a muscle, neuron, or gland cell

I) Action potential reaches synaptic knob

Explanation:

it cools slower in the earth meaning the crystals have more time to form than lava on the surface

the farther away the object is from the central star (the sun) it's gravitainal pull on the object is weaker when it is farther
