CA-4 = CA-2 + CA-3, is best regarded as an option, and not as an equation, since its execution depends on  system context. .On one hand it creates a CA-4, while on the other, it kills it. The second option eliminated also the injured CA-4. Yet when failing, the injured process continues growing chaotically, like in the next experiment in which CA-1 failed to kill the injured CA-4.

In order to protect itself,  stem process kills any process which survives longer than a given time, This mechanism is called apoptosis. It guarantees that all processes in a system are solutions. If left alone a perturbed process assumes four kinds of behavior:

1. Does not change
2. Becomes a different solution.
3. Becomes a non-solution (chaotic).
4. Dies

Apoptosis eliminates non-solutions. If killing a damaged process too soon, it may eliminate a solution with a longer period.. On the other hand, a prolonged non-solution threatens to wipe the system out.

Proliferon

A zygote is planted, and becomes a stem process, which plants stem cells of transient processes, and controls them. Ultimately the proliferon finds its solution, called Homeorhesis, and maintains it until an injury has changed it.
