A scientist adds 5 mcg of the mineral cadmium to the daily diet of 100 4-week-old laboratory mice. After twelve weeks, the resea
rcher weighs and takes blood samples from each mouse. According to her findings, the mice lost weight during the 12-week period and they have abnormal levels of certain hormones in their blood. Based on this information and your knowledge of scientific research, what would you tell the researcher about her findings?
The information is not complete and the way she designed her study is not only valid but also not useful findings.
She did not take any normal control to check the status of normal mice along with subject mice or tested mice. Along with this she did not mention the results in details only said about the weight loss and hormone disturbances.
In research when a significant result is found that means it has been shown through statistical tests that one variable has had an effect on another. If it is a low effect size though it means that the effect is not large enough to prove a hypothesis.
D. Chemical mediators are released from presensitized mast cells.
Explanation:
mast cells play an important role in allergic reactions and responsible for releasing histamines and potent mediators tat directly affect inflammatory cells. the chemical mediators released by presentized mast cells play important role in etiology of the acute response phase of extrinsic (atopic) asthma.
