The life stages of two animals are shown. Which statement best describes a stage in the animal's development?

• Animal 1 changes form to become an adult.

• Both animals look like the adult while growing.

• Animal 2 reaches adulthood in a shorter period of time.

• Both animals have young (offspring) that live in similar habitats.

The life stages of two animals are shown. Which statement best describes a stage in the animal's development?

• Animal 1 has complete metamorphosis, while animal 2 has incomplete metamorphosis.

• Animal 1 has incomplete metamorphosis, while animal 2 has complete metamorphosis.

• Both animals have complete metamorphosis.

• Both animals have incomplete metamorphosis.

A gardener plants seeds in the garden. After the flower stage, the fruits and vegetables grow. A table of how many days are needed for some plants to be ready to harvest is shown. Which statement is supported by the data shown in the table?

• Pumpkins take the most time to sprout and to be ready to harvest.

• Green bean seeds sprout faster because they are smaller than other seeds.

• Cucumbers are ready to harvest in less time than watermelons.

• Watermelon seeds take longer to sprout because watermelon plants produce large fruits.

Students observe these diagrams showing the life cycles of an oak tree and a lady beetle.

Which inference can be made by comparing these diagrams?

• Plants require less energy than insects require to undergo changes from a young organism to a mature (adult) organism.

• Insects and plants follow a series of changes that allows them to survive and reproduce.

• Insects are more likely than plants are to adapt to changes in the environment to survive.

• Insects and plants are dependent on one another for survival.

Lacewings are insects that hatch from eggs. Which of these correctly compares the LACEWING life cycle with the FROG life cycle?

• Adult lacewings lay eggs, but adult frogs give birth to live larvae.

• When they hatch, young lacewings and young frogs look different from their adult forms.

• When they hatch, both lacewings and frogs have long legs for jumping.

• Both adult lacewings and adult frogs have more legs than they had as larvae.

The abalone is a type of sea snail. Adult abalones slowly crawl over rocks near the shore, while larvae float in the water. Which organisms have a life cycle that is most like that of abalones?

• humans

• frogs

• birds

• snakes

One stage in the life cycle of an apple tree is the release of seeds. Which of these animal activities is most like the stage of the life cycle in which seeds are released?

• A snake shedding its skin

• A bird laying an egg

• A swarm of bees leaving a hive

• A tadpole growing into an adult

Some students are investigating the life cycle of the spotted salamander. They learn that these salamanders must live close to water and lay their eggs in water. After 20-60 days the eggs hatch as larvae that must stay in the water until they mature (grow) into adult salamanders. The students infer (guess) that the life cycle of the spotted salamander is similar to the life cycle of the FROG, because both animals -

• have long tails and strong jumping legs as adults

• live near water and produce larvae with wings

• lay eggs in water, which hatch into larvae that live in water

• produce offspring that hatch from eggs and look like adutls

Some species of rain forest frogs reproduce in the moist leaf litter on the forest floor. These frogs do not need a nearby body of water to complete their life cycle. Which stage of the typical frog life cycle is most likely missing from their life cycle?

• egg

• tadpole

• froglet

• adult frog

At which stage in the life cycle of a plant are seeds produced?

• 
• 
•
