What does the presence of blue color means in variegated leaf experiment of photosynthesis?
By blue color I assume you mean an added dye that shows how some parts of the leaf can photosynthesize and others not. The easiest of these experiments is to place the leaf in boiling ethanol (alcohol) and when drained of colour spread out on a flat surface. Soak the leaf in iodine and the green parts will turn blue/black and the non green parts will stay the yellowish brown colour of iodine. The green parts contain starch (a more compact form of glucose) which makes iodine turn blue/black. The blue/black is what will show starch is present.

Why do they put dye through your veins?
Medical procedures involving the use of "dye" through your veins enables the veins to show up more clearly when scanned by a CT/MRI machine, or similar. This is useful when assessing levels of blood-flow around the body, and will show up where any "blockages" may be occurring. Similar procedures involve ingesting (swallowing) a small amount of "dye"; this type of process would be used to assess the stomach, small intestine and colon. Usually the "dye" is actually a non-harmful radioactive substance, as opposed to a liquid of a concentrated colour (which is how most people consider "dye"). It is completely harmless, and breaks down within a few hours of being injected.

What is a Tri-phasic ct scan?
A tri-phasic CT scan is a scan which will show three different stages of dye uptake in the body. The first phase will be before the injection of the dye, the second stage will be for when the dye is in the arteries (roughly 20 seconds after injection) and the third phase will be when the dye has reached the veins (a few minutes later). Sometimes a fourth scan is also done to show the dye uptake in the kidneys and bladder. A tri-phasic scan clearly delineates lesions in the liver and will show problems and irregularities in the arterial and lymphatic system.

Often an x-ray after the bladder has been emptied is taken as well.
