Answer:

Yes, ink chromatography can be used by the teacher to find out whether or not a student has changed answers after a test has been graded.

Explanation:

Ink chromatography is a procedure of separating out of the desired ink from the mixture of various other types of inks or dyes.  When any ink is mixed with any solvent meant for it, then it dissolves and may be distinguished from the other ink. Also another fact is helpful, which indicates that some ink are water soluble and some are alcohol soluble. Different types of ink pen uses various types of inks, when this is mixed with certain solvents the components of the mixture thus obtained forms a banding pattern which is very unique to that particular. This is also called ink chromatograph.

Explanation:

According to the information we have gathered from the vehicles sent to Mars and the data they collected and analyzed, "Minerals of types known to form in liquid water" on Mars. There is "abundant water ice" and also "dried-up river beds".These statements actually exist.

"Surface pools of liquid water" does not exist on Mars. "A network of straight-line canals", "cities built by an ancient civilization" and "frequent rainfall and snowfall" also do not exist on Mars according to the data.

We do not have any information to prove the existense of "underground pockets of liquid" and "microscopic life" but they are possibilities.

I hope this answer helps.
