The picture shows the grasshopper’s stages of incomplete metamorphosis. Grasshopper Metamorphosis.

Why are the grasshopper's changes considered incomplete rather than complete metamorphosis?

• Grasshoppers are insects.

• Grasshoppers hatch from an egg.

• Grasshoppers have an adult stage.

• Grasshoppers have 3 stages of metamorphosis.

In what way are ferns different from flowering plants that produce seeds?

• The stems of ferns are woodier than the stems of seed producing flowers.

• The leaf of a fern does not include structures to move nutrients through the plant.

• Ferns reproduce using spores rather than seeds produced by most flowering plants.

Many kinds of animals live in the Everglades, including alligators, Florida panthers, and manatees. What characteristics do all three of these animals of the Everglades share?

• They all eat only fish.

• They all have a backbone.

• They all give birth to live young.

• They all make their homes in the water.

Complete metamorphosis and incomplete metamorphosis describe how some insects develop from egg to adult. Which statement correctly describes these life cycles?

• Complete metamorphosis requires the insect to develop into a pupa before becoming a larva.

• Complete metamorphosis requires the insect to develop into a pupa before becoming an egg.

• Incomplete metamorphosis requires the insect to develop into a nymph before becoming a larva.

• Incomplete metamorphosis requires the insect to develop into a nymph before becoming an adult. 

Metamorphosis refers to the way that certain organisms develop, grow, and change form. What are the stages of incomplete metamorphosis?

• egg, larva, adult

• egg, nymph, adult

• egg, larva, pupa, adult

• egg, pupa, larva, adult

 When the wind blows, Aaron sees small, brown objects falling off of a maple tree in his backyard. The falling objects spin like helicopter blades and can be found throughout his neighborhood. Which part of plant reproduction is Aaron observing?

• seed production

• seed dispersal

• germination

• pollination
