The plants shown in the photo can be classified together because ________ .

• all of them are trees

• all of them produce cones

• all of them reproduce through spores

As part of a unit about organisms, students are trying to develop a model to classify different animals based on their characteristics. One of those characteristics includes determining if an animal can be classified as a vertebrate or invertebrate.

In order to classify an animal as a vertebrate, the students will need to determined if it

________ .

• is cold blooded

• has fur or feathers

• gives birth to live young

• has a backbone and spine

Based on this model, what is happening during the stage of the plant’s life cycle

labeled with the letter ​R​?

• The plant has matured and will begin to flower soon.

• Seeds are produced in the fruit for for reproduction.

• The seedling is beginning to develop into a mature plant.

• The plant is beginning to germinate as it grows from the seed.

Based on the student’s observations, what stage of development is she observing?

• Germination

• Mature Plant

• Seed

• Seedling

Which of the following ​best​ describes the life cycle of an amphibian?

The Arctic fox is a species of fox that lives throughout the Arctic tundra of the Northern

summer, the coat changes to brown.

Which of the following characteristics of the Arctic fox is influenced by its

environment?

• Arctic foxes hunt lemmings.

• Arctic foxes have very sensitive hearing.

• Arctic foxes change color with the seasons.
