Answer: Irreducible complexity
Explanation:
Irreducible complexity can be defined as characteristic of complex system it is impossible to reduce the complexity of the system by removal of any parts to maintain the functionality of the system. The given situation is an example of irreducible complexity. The increased levels of tryptophan will inactivate the synthesis process but it is again reactivated when the levels decreases this is suggestive of the fact that it is impossible to reduce the complexity of the system.

The three types of stress that act on Earth's rocks are compression, tension, and shear.The Earth's crust is broken into several parts which are called plates. When these plates are being pulled or pushed together, the Earth's stress now occurs.
