Organisms can have positive or negative impacts on the ecosystem they live in. the cane toad, or rhinella marina, was introduced to the hawaiian islands in 1932 by sugar cane farmers. farmers released the toads in their crops to control pests that were damaging the sugar cane. the cane toad has few natural predators, as it secretes a poisonous toxin from its skin that deters larger organisms from eating it. as a result, the cane toad population thrived and grew to number hundreds of thousands by 1935. width="379" which role does the cane toad play in the hawaiian islands?
a. native species
b. invasive species
c. uncontrolled species
d. endangered species

Turtle hatchling survivorship rate is low in many turtle species due to predation. amanda researched the predatory rate on a species of turtle eggs in the red river. the eggs were harvested from trapped turtles and the egg's cloaca film (reproductive discharge) was either washed off or left on once gathered. research suggests that predators use the female's cloaca scent to locate the eggs. the eggs were only handled when wearing gloves and then reburied along islands where the turtles were trapped. the nests were monitored by cameras and manually on foot and data on nest predation were recorded. a. based on the experimental design, what is the dependent variable? b. based on the experimental design, what is the independent variable? c. based on the experimental design, what is the control?

Which statement best describes a typical difference that could be found between the "analysis" and "conclusion" sections of a lab report? a) only the "conclusion" describes errors that occurred during the experiment, and only the "analysis" section suggests further research.b) only the "analysis" section includes specific data comparisons, and only the "conclusion" section suggests further research.c) only the "analysis" section discusses whether the original hypothesis was supported, and both sections include graphs of data.d) only the "conclusion section discusses whether the original hypothesis was supported, and both sections suggest further research.(the answer is b i just took the test)
