Benedict solution. This is a test for the presence for glucose. Remember, diabetes is when there is too much glucose in a persons body and so it is present in the urine as well. Once benedict solution is added the colour changes opposite the colour spectrum depending on how much glucose is present. It changes from blue back to green to yellow all the way to orange and red as more glucose is present.
The scientific reasoning behind this is because benedict solution contains copper. Glucose tends to give electrons away and so is called a ‘reducing sugar’. The electron is given to copper and this as a result is a cause for the change in the colour of the solution.
I think the answer is emphysema. the definition of it is "a condition in which the air sacs of the lungs are damaged and enlarged, causing breathlessness."
the definition for asthma is "a respiratory condition marked by spasms in the bronchi of the lungs, causing difficulty in breathing. It usually results from an allergic reaction or other forms of hypersensitivity."
pneumonia is an infection where the lungs start to fill with fluid.
Cancer is usually a tumour inside the lungs.
The answer would be A
Answer is Positron Emission Tomography.
Positron emission tomography (PET) is an imaging test based on nuclear medicine. In PET imaging a small amount of liquid radioactive material such as simple sugar (glucose) called fluorodeoxyglucose (FDG) is injected into the bloodstream. It is accumulated in the body and emit gamma rays which are detected by PET. Many diseases such as cancers, brain diseases and heart diseases are diagnosed by the PET imaging.
