Answer:
Luciferin is used, for example, in reporter gene assays to study gene regulation and function where expression of the luciferin-tagged reporter is a marker to indicate successful uptake of the gene of interest in recombinant DNA techniques. Luciferase is a heat-sensitive protein that is used in studies on protein denaturation, testing the protective capacities of heat shock proteins. Luciferase is an enzyme used for bioluminescence by various organisms in nature, most famously the firefly. The scientist produces a construct in which the regulatory region of a target gene is fused with the DNA coding sequence for luciferase

The correct answer is option B
B. The treated glioblastoma cells were cultured in the presence of an inhibitor from umbilical cord stem cells, but the control cells were cultured without the inhibitor.
Answer: C. Positive feedback mechanisms are overwhelmed.
Explanation:
Homeostasis, is the maintenance of a normal internal environment, in the face of external and internal disturbances, so that the functions of cells and systems of the body are preserved. This is accomplished primarily through feedback systems, so when a system is disturbed, a diversity of local responses, systemic reflexes (rapid reactions and automatic stimuli) and long-term adjustments are activated to bring the system back to its normal equilibrium point.
Most systems are controlled by negative feedback mechanisms, with the controlled variable being able to "turn off" its release, in the same way as a thermostat controls the temperature of a room. So, in this context, too much positive feedback would be related to harmful effects, such as homeostatic imbalance.
