4 Points Observation: Red-eyed tree frogs lay clusters of eggs on leaves overhanging bodies of water. The eggs develop for 6-8 days before hatching as tadpoles. However, if the egg cluster is attacked by a predator, such as a snake, before development is complete, the embryos will rupture their eggs and hatch prematurely. Question: Why do snake-disturbed red-eyed treefrogs hatch prematurely? Hypothesis: Tree frog embryos sense olfactory cues produced by the snake and respond by rupturing their eggs prematurely. Examine the following statements and indicate which are alternatives to the above hypothesis and which are not alternatives Q7.1 Tree frog embryos have an innate ability to hatch prematurely when they sense the presence of a predato 1 Point O Alternative Hypothesis O Non-Alternative Hypothesis Q7.2 Tree frog embryos rupture their eggs prematurely in response to visual cue of a snake attacking. 1 Point Alternative Hypothesis O Non-Alternative Hypothesis

Q7.3 Tree frog embryos rupture their eggs prematurely in response to tactile cues (e.g., they feel vibrations) produced by a snake attacking their egg cluster. 1 Point O Alternative Hypothesis O Non-Alternative Hypothesis Q7.4 The ability to hatch prematurely in response to a snake attack decreases the risk of predation on tree frog embryos. 1 Point O Alternative Hypothesis O Non-Alternative Hypothesis
