An organism that has chloroplasts and vacuoles and moves using a flagellum would be classified as an autotroph.
<h3>What is an autotroph?</h3>
An autotroph is an organism that can generate its own food, which is due to a chemical process called photosynthesis.
Photosynthesis occurs in a specialized organelle called chloroplast that traps sun radiation to convert it into chemical energy.
In conclusion, an organism that has chloroplasts and vacuoles and moves using a flagellum would be classified as an autotroph.

<h3>
Answer:</h3>
The generation of local currents.
<h3>
Explanation:</h3>
An action potential at the axon hillock generates local currents that depolarize nearby sections of axon to threshold. This change in membrane potential causes voltage-gated Na+ channels to open in the adjacent axon segment. This generates/regenerates the action potential in the adjacent segment, causing the action potential to propagate away from the axon hillock.
