The correct answer is the mountain frogs in a lab setting with no UV rays exposure.
The frog populations, which do not acquire the ultraviolet radiation would function as a good control group. In this case, as the influence of the radiation is the variable under examination, thus, a group that acquires no radiation would exhibit no variation, and thus, would function as a control group that could be compared against the frogs, which do receive the radiation.
Answer:
The immune system initiates inflammatory response while the immune response involves how this harmful substances are recognized and destroyed.
Explanation:
The inflammatory response is the normal response of the body's immune system to injuries to tissues by bacteria, trauma, toxins, that enter the body.
