(Use the fоllоwing infоrmаtion for the next two questions) The emerаld аsh borer is considered one of the most destructive invasive species for trees in North America, specifically targeting ash trees. Most of the damage comes from the larvae which bore inside the tree for nutrients while disrupting the tree’s nutrition and water transport systems, ultimately leading to the tree’s death. Dr. Garnet wants to test whether a new injectable insecticide is effective against the emerald ash borer larvae. This insecticide prevents the larvae from feeding, ultimately leading to their starvation. To test the insecticide, Dr. Garnet finds a forest plot containing 50 infected ash trees. Dr. Garnet injects 25 of the trees with the 100 mL of the new insecticide and the remaining 25 trees with 100 mL of a neutral aqueous solution (similar to saline for humans). Dr. Garnet then determines the percent of larvae killed by counting the total number of living and dead larvae in the sample of trees.Which of the following is the best scientific mechanistic hypothesis for Dr. Garnet’s study?
