Before conducting this experiment what would be the most important thing to check to ensure accurate results f. the diameter of the objects used g. the table where you will record the data h. the weight of the objects used j. the motion detector 55. According to Data Table I what was the difference in velocity between minutes 3 and 4 a. m s b. m s c. m s d. m s Passage IIX One phenomenon studied by ecologists is the growth and regulation of populations. Population growth can be restricted when resources are limited. Competition for resources can also have an effect on population growth. Three experiments were conducted on various insects to test the validity of these statements. The table that follows is a summary of all three experiments. Experiment 1 Two beetle species and caterpillars were studied Six of each insect were grown in .
