An action potential traveling along the entire length of an axon demonstrates <u>continuous</u> propagation.
Propagation of action potential:
- An action potential is created by the rapid input of Na+ ions and the slightly slower outflow of K+ ions.
- Action potential initiation occurs in the axon's first segment, and as action potentials spread throughout the axon, cells can convey their output to synapses located further distant from the cell.
- The action potential conducts continuously in unmyelinated axons, whereas it conducts rapidly and saltatorily in myelinated axons where sodium channels are concentrated near the nodes of Ranvier.
- The action potential always advances in the same direction whenever a local current begins to form due to the prior axon segment still being in the absolute refractory period. As a result, action potentials travel away from the location of their generation and do not change course.

Answer:
1. mushroom
2. nucleus
3. eukarya
4. animalia
5. button mushroom
Explanation:
1. Mushroom because everything else in the list is an animal, while a mushroom is a fungi.
2. Nucleus because eukaryotic and prokaryotic are types of formations of a cell, while a nucleus is part of a cell and not a cell formation.
3. Eukarya because the Eukarya include all animals, plants, fungi, and protists. These organisms are eukaryotes, meaning they have membrane-enclosed nuclei within their cells. The Bacteria and Archaea are both considered prokaryotes, because their cells lack true nuclei, meaning a membrane does not enclose their genetic material.
4. Animalia because fungi and plantae are stationary organisms, while animalia are mobile. (ex. fungi and plantae= roots and animalia= feet/ not attached to one place)
5. Button mushroom because sunflowers and oak trees are producers, while a button mushroom is a decomposer.
