A student while experimenting on carbon dioxide is given out during respiration, he forgot to take two precautions as given below :

a) To hang a test tube containing KOH solution in the conical flask.
b) To put moist seeds in the conical flask.

State the result of the experiment due to the mistakes caused by him.
