Is it possible to make a photo's EXIF look like it was taken with a DSLR?

Yes, it is possible. But you should not do this. Being dishonest with your teacher is never a good move. If you have a mirrorless interchangeable lens camera with a large sensor, you may be able to ...

Do mirrorless cameras have more sensor noise because they are constantly exposed to light?

DSLR camera sensors are only exposed to light when the picture is taken, so the sensor presumably produces less noise than if it was always exposed to the light. I find support for this in the way ...

Why do lenses for larger sensors tend to have shallower angles?

This is simply where the market is converging to at the moment. The typical kit lens is still 18-55mm on an APS-C sensor but most people find wider angle more useful, so some manufacturers made a few ...

What's the advantage of a DSLR's "previewer" viewfinder, since I have observed that mirrorless cameras appear to have the same thing?

DSLRs have a direct, optical path through the lens. (Well, a reflected direct path.) You are seeing the scene with your eyes. Mirrorless cameras with a viewfinder actually use a small LCD screen — ...
