4. Dr. Luis designed an experiment to determine the effect that
ethylene has on the growth of the Justicia mirabiloides plant, an
endemic plant in Puerto Rico. For this, Dr. Luis made sure that all
the plants (5 plants) in the experiment were under the same
conditions, such as: pots, soil, temperature and humidity. However,
Dr. Luis did not have the expected results. What would be a
possible explanation for the doctor not obtaining the expected
results?(choose the best option)
a. Genus and species
b. Humidity and temperature
c. The sherds and the floor
d. The amount of plants
Answer- b - humidity and temperature.
As it is mentioned the plant is endemic to puerto rico , meaning it is found just commonly in that region . It might be due to the climate , soil and other external factors . An endemic plant will have best growth in its natural habitat to which it is adapted . Changing the habitat affects the dependant variable which is growth.
Hope this helps,if it does please give it a positive rating thank you!

The researchers designed this experiment to test their hypotheses: They grew ragweed plants in growth chambers at three different levels of CO2: the pre-industrial level, 280 µmol mol-1 the level in the year 2000, 370 µmol mol-1 the level projected for the middle of the 21st century, 600 µmol mol-1 They then measured the amount of pollen produced by sample plants grown under each condition and determined the concentration of protein allergens in that pollen. Here are the data they...
