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:
b. testing new conditions.......
Answer:
They regulate the cell cycle by phosphorylating other proteins
Explanation:
they are serine-threonine kinases, they play an important role in the phosphorylation of other proteins. Cyclin-CDK complexes phosphorylate substrates appropriate for a particular cell cycle phase and without that, the cycle cannot continue.
Answer:
they tend to overlook details
