Document Summary
Which stage of larval development was used, differences in size so run experiments with comparisons of size. Gut content acts as ice nucleator - possible that fred has fed them and joe had starved them - 2 groups for each, one fed and one starved. Soil/habitat - humid vs dry, carry out experiment at different humidity. Say why and basic principles of how you would test it. Explain as fully as possible, don"t use vague terms. Not all offspring will survive - good thing for population control. Ability to change habitat e. g. frogs terrestrial to aquatic. Recently found fossil insects with great resemblance to fossil plants. Fire ants - sting so bad can enough can cause anaphylactic shock. Caterpillars when attacked rear up and extrude organ which releases odour. Defence carried out in sequence as defence compound production is expensive. If also mimicking the habitat, it can become camouflaged.
