| Rina set up the apparatus for demonstrating that \[C{{O}_{2}}\] is released during respiration of germinating seeds. After 2 hours when she observed the setup she did not find the water to rise in the bent tube from the beaker. The reason could be because: |
 |
| (a) the beaker has coloured water. |
| (b) The set-up is air tight. |
| (c) no oxygen is available to seeds for respiration. |
| (d) carbon-dioxide is not being absorbed. |
Answer:
(d) carbon-dioxide is not being absorbed.
