Answer:
After about a week you will find that the lime water turns white in the test tube with sprouts. Lime water turns white when CO2 is dissolved in lime water. It means that carbon dioxide gas was produced by the sprouts. Carbon dioxide is produced by breathing of sprouts which take oxygen and breath out CO2.

Answer:
The germinating seeds will have a higher rate of oxygen consumption than the non-germinating seeds because the germinating seeds are living and need extra oxygen so that they can grow, whereas the non-germinating seeds are not nearly as active and won't respire as much.
