PLEASE ANSWER ALL PARTS OF THE QUESTION AND USE THE IMAGE FOR A GUIDE A biologist is studying the effect of fertilizer on a species of endangered plant in a specific area of land divided into 32 equal sized plots. (See diagram.) Plots numbered 1—16 are in deep shade from the trees for most of the day while periodic flooding occurs in the areas numbered 17—32.   The biologist chooses 16 plots at random and applies organic fertilizer. The other plots receive non-organic fertilizer. At the end of the study period, the percentage increase in the number of this plant is measured in each plot and compared for each type of fertilizer. Is this an experiment? Briefly explain your answer.     A biologist is studying the effect of fertilizer on a species of endangered plant in a specific area of land divided into 32 equal sized plots. (See diagram.) Plots numbered 1—16 are in deep shade from the trees for most of the day while periodic flooding occurs in the areas…

High-Speed Train Company The tourism director for a hlgh-speed train company was Interested in flnding out the precise time the train passed by some special landmarks. To help her figure this out, she began by collecting some data for the Palmetto traln that originates from New York City Penn Station and ends at Richmond, VA, stopping at varlous locations along the route.
