When an action potential arrives at the axon terminal of a motor neuron, which ion channels open?
HACTEHA [7]

Answer:

Calcium voltage gated ion channels

Explanation:

There are two types of ion channels involved in the neuromuscular junction and end plate potentials: voltage-gated ion channel (responsive to changes in membrane voltage which cause the voltage gated ion channel to open) and ligand-gated ion channel (responsive to certain molecules such as neurotransmitters).

The resting membrane potential of a motor neuron goes from -70mV to -50 with a higher concentration of sodium outside and a higher concentration of potassium inside. <em>When an action potential propagates down a nerve and reaches the axon terminal of the motor neuron, the change in membrane voltage causes the calcium voltage gated ion channels to open allowing for an influx of calcium ions. </em>These calcium ions cause the acetylcholine vesicles  to release acetylcholine via exocytosis into the synaptic cleft.

I hope you find this information useful and interesting! Good luck!

What is one similarity between natural selection and artificial selection?
Tpy6a [65]

Answer:

B- environmental factors do most of the “selecting.”

Explanation:

Natural selection is the environment that the organism lives in, and the process which that organism changes by.

Artificial selection is when humans intervene and create an organism that isn't suited for their specific environment, but rather for the humans own liking.

Think of breeding dogs to be smaller, or more fluffy and adorable. These are not traits to help them survive in where they original environment was.
