Question

please its urgent que ans me que = to show experiments that carbondioxide is given out during respiration ​

Answer 1

Answer:

The rise in the level of water indicates that CO2 is produced by germinating seeds during respiration. Actually, the germinating seeds respire and produce CO2, which is absorbed by KOH solution. This creates a vacuum in the conical flask. The air present in the bent glass tube moves into the conical flask.
