The first one is solids since they have no kinetic energy
The second one is chemical since the change of colors shows that there is about to be a chemical change
The third one is C
The Endothermic process definitely fits melting
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.

The correct answer is (c.) unicellular eukaryotes. Unicellular eukaryotes apply to most protists. Protists are grouping of eukaryotic cells that do not form any natural group. These eukaryotes include the Golgi apparatus and mitochondria, and for plants they include chloroplasts.
