PLEASE ANSWER ! When Francisco heard that plants compete for space, he decided to test this idea. He bought a packet of marigold seeds and some potting soil. He set out 30 plastic drinking cups. In five cups, Francisco placed 200g of potting soil and planted 1 seed in each cup so they were buried in 1cm deep in the soil. He then watered the seeds with 50mL of distilled water and placed them on the windowsill. In another group of five cups, Francisco placed 200g of potting soil and planted 2 seeds in each cup so that they were buried in 1cm deep soil. He then watered the seeds with 50mL of distilled water and placed them on the windowsill. Keeping the same procedure, Francisco planted 4 seeds in another five cups, 8 seeds in another five cups, 16 seeds in the next group of five cups, and finally, 32 seeds in each of the last five cups. Each cup was watered every other day with 50mL of distilled water for 50 days. As the experiment progressed, Francisco recorded the color of the plants and the height of the plants every 5 days for 50 days 1:What is the NULL hypothesis?

2:What is the control group?

3:What is (are) the experimental group(s)?
