For an experiment I am growing 12 cherry tomato plants. My hypothesis is Tomato plants will grow will grow faster if full concentration of fertilizer is used, and my aim is: to determine if using fertilizer will effect the growth rate of tomato plants. 3 of the plants aren't getting fertilized, 3 are only getting 1/3 of full concentration, another 3 are getting 2/3 of full concentration while the last 3 are getting full concentration of fertilizing. Which 3 are the independent variables, the dependent variables, the controlled variables and the experimental variables? and is my hypothesis and aim written correctly?
biology help pleasee?
