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:
The given question says that a student has constructed a model of cellular transport using fences and several gates.
This model can be used to demonstrate the cellular transport.
The gates of the fences can be supposed as the protein pumps and the other fence demonstrates the lipid bilayer.
Let’s suppose in the fence, there are many cattles, and outside, there are less cattles, but the student open the gate and bring more cattles inside the fence. In this case, the transport of the cattles is similar to the active transport of the molecules using protein pumps. At cellular level, the energy for the active transport is provided by ATP molecules.
Now, let’s say, the student wants to feed the cattles with some nutrition rich food, which can help in maintaining the health of the cattles. The student fills his car with the cattle food and he enters inside the fence through gates. In this case, the food was not present in the fence, but was abundant in the outside environment, so, the diffusion would occur. But food cannot come self, without help of others, so, the movement is facilitated by the car, as it is done by the carrier proteins. Hence, it is an example of facilitated diffusion.
