Jackie read that aloe vera promote healing of burned tissue. she decided to investigate the effect of varying amounts of aloe vera on the regeneration of planaria (a freshwater flatworm), regeneration is the process of growing back a lost body part. jackie bisected (cut in half) five planaria to obtain 10 parts (5 heads and 5 tails) for each experimental team. she applied concentrations of 0%, 10%, 20%, 30%, and 40% aloe vera to the teams. fifteen milliliters of aloe vera solutions were applied. all planaria were maintained in a growth chamber with identical food, temperature, and humidity. on day 15, jackie measured the amount of regeneration of the planaria parts and categorized regeneration as full, partial or none.1. what is the hypothesis (if/then statement) for this particular experiment? 2. what are the dependent variable and the independent variable? 3. what controls are they using in their experimental setup? 4. when they performed the experiment, they collected the data shown below: percent aloe vera count of regenerated planaria0% 210% 520% 730% 35. should the hypothesis be supported or rejected based on the experiment? why?
