Below are sample questions representative of the exercises included on this worksheet and related 3.23 Metamorphosis in Insects and Amphibians skill assessments:

Problem 1Difficulty: Mastery
Which summary is the most complete and accurate?
AOnly frogs start life as eggs.
BGrasshoppers and butterflies both have tadpoles.
CButterflies, grasshoppers, and frogs all use the same stages.
DButterflies use complete metamorphosis with egg, larva, pupa, adult; grasshoppers use incomplete metamorphosis with egg, nymph, adult; frogs change from egg to tadpole to froglet to adult.
Solution & Explanation:This choice correctly names and compares all three life cycles using the right stage terms.
Problem 2Difficulty: Mastery
Use the side-by-side butterfly and grasshopper comparison image. Which improvement would make it more useful for comparing the two life cycles?
AHide the egg stages.
BRemove all stage names.
CUse matching arrows and clear labels so the order of changes is easy to compare.
DShow only the adult animals.
Solution & Explanation:Matching arrows and labels make it easier to compare stage order and life cycle structure.
Problem 3Difficulty: Mastery
A poster title says, 'All animals have larva and pupa stages.' Which evidence from this skill disproves the title?
ASome insects have wings.
BGrasshoppers have nymphs, and frogs have tadpoles and froglets instead.
CAdult frogs can jump.
DAll butterflies begin as eggs.
Solution & Explanation:The title is too broad. This skill shows examples where animals use nymph, tadpole, and froglet instead of larva and pupa.
