Luke recently moved to a new apartment and wants to grow houseplants but isn’t sure which room will be the best fit for them. Apply your knowledge of the scientific method to recommend a strategy for Luke to follow when determining the ideal location for houseplants in his new apartment.  What order should he use to perform the following actions? A. Luke should compare the growth and health of each individual to determine if his hypothesis was correct and to ultimately determine which location in his apartment is ideal for the selected houseplant. B.  He should  form a hypothesis based on his research that a specific plant will do best in a specific location in his apartment. C. He should test his hypothesis by acquiring several individual plants of that type which are potted in identical containers with identical soil. D. Luke should place each plant in a unique location in his apartment, with one plant being located in the spot that he predicted would be ideal. E. He should test his hypothesis by acquiring several individual plants of that type which are potted in identical containers with identical soil. F. Luke should perform research on the needs of various houseplants and determine which type of houseplants might be best suited to his apartment. G. Luke should maintain the plants identically over the study period and observe each for growth and overall health.
