Title:Research Using Scientific Method<br>Description:<br>A. Research Using the Scientific Method<br>Many researches had made use of the scientific method to device a scientific query that will test the effect of different substances to the cell division by observing changes in<br>the organisms' physical attributes. In this activity, two substances, A and B, are tested on their effects on the cell division of onion plant. Onion bulbs were submerged and<br>allowed to grow together with the test substances and the length and number<br>experiment. Use the table and analyze before you answer the questions that follow.<br>Here is a video that shows the procedure of growing onions using water. The experiment is based on this. Use only as a reference. https://www.youtube.com/watch?<br>v=QroXnfmhVTg<br>growing roots and shoots were measured.
