Answer:
The options are
a.cooling of the power plant
b.mining of uranium
c.storage of radioactive waste
d.monitoring the reactor
The answer is b.mining of uranium
Explanation:
Uranium is known as a radioactive element which is used as a fuel to power a nuclear energy plant. Mining of uranium could cause it to mix with air and water which results in contamination.
When contamination occurs and it gets into the body of humans or animals by inhalation or ingestion it poses a high risk of cancer and kidney damage.
 
        
             
        
        
        
Answer:
is common because it promotes homeostasis
Explanation:
The negative feedback loop is a mechanism wherein a change in some condition stimulates a response to counteract the changed condition and thereby, the homeostasis is restored. 
For example, an increased blood glucose level above its homeostatic level stimulates the secretion of insulin hormone from the pancreas which in turn stimulates the absorption of glucose from the blood into the cells (specifically the liver and muscle cells) and thereby restores the normal blood glucose levels. 
Most of the processes in the human body are regulated by negative feedback loops to maintain the homeostasis.
 
        
             
        
        
        
Answer: 
To maintain homeostasis
Explanation:
Effectors are organs, cells or tissues that provides the required output after receiving a feedback from the control center. Nerve impulse instructs the effector to bring things into balance and required range. They then influence the magnitude of stimulus and maintain homeostasis.
