basic
neutral
acidic
clear selecti
buffers are important in biological systems because they: 2 p
increase the acidity of solutions
eliminate all acids and bases
maintain a stable ph in body fluids
neutralize water in cells

Explanation:

Litmus paper is an indicator. Red litmus paper turns blue in basic solutions. Buffers resist changes in pH. In biological systems, they maintain a stable pH in body fluids which is crucial for proper functioning of enzymes and cells.

Answer:

1. Basic
2. Maintain a stable pH in body fluids
