Can a resistor be used in place of a potentiometer?

Instead of only one resistor, two can be used to substitute a pot. Both would be fastened to the pot's centre pin, and the other two ends would be fastened to the other two pins. Any desired volume level might be selected by sizing up to two resistors. The sum of the two resistors ought to be near to the pot's resistance.

Will LCD function without a polarizer?

Polarizers function by limiting the kind of light that reaches the pixel layer of the LCD. A polarizer is used to produce discernible images. You wouldn't be able to view the images an LCD produces without them.
