Give the full form of CT and MRI. How are they different from each other? Where are they used?
CT-Computed Tomography. It uses X-rays to generate 3-D images of internal organs. MRI-Magnetic Resonance Imaging. It uses strong magnetic fields and non-ionising radiations to detect pathological and physiological changes in the living tissue accuratily.
Both are used in cancer detection.
Many secondary metabolites of plants have medicinal properties. It is their misuse that creates problems. Justify the statement with an example.
