He went to the Galapagos Islands and studied different species of finches and plants that had adapted differently on the different islands.
Answer:
The correct answer is the first statement.
Explanation:
A fundamental stimulus-response coupling mechanism that helps various species to react and sense different modifications taking place in various distinct environmental circumstances is known as a two-component regulatory system. Though this system is found in almost all the domains of life, however, it is generally witnessed in species like bacteria, mainly in the Gram-negative and cyanobacteria.
In case, if the response regulator turns completely phosphorylated because of the absence of phosphatase activity, the cell would become insensitive towards the environmental stimulus. This generally happens as the cell will lose its tendency to sustain the response cycle because of the imbalance in the dephosphorylation and phosphorylation system that helps in sustaining the response of the cell towards a specific environmental stimulus.

- Compression of the nerves, for problems such as a spinal cord injury or a pinched nerve in the neck or back
- Dehydration
- Low levels of electrolytes such as magnesium, potassium or calcium
