Six bean seeds were left to soak in cold water. Three of these were then boiled and allowed to cool. The boiled seeds and the unboiled seeds were cut into small pieces and placed on the top of agar jelly that contained starch. After two days, all the seeds were taken away and the jelly was tested using iodine solution. The diagram illustrates the outcome of the experiment. What is the explanation for the results with the non-boiled bean seeds?
- AThey absorb iodine.
- BThey absorb starch.
- CThey contain acid.
