- Structures support survival. Breathing is essential for whale survival.
- Identify the structure that supports behavior by allowing a chameleon to capture insects quickly.
- A long, sticky tongue. The sticky surface traps prey when extended rapidly.
- Which four life needs can structures support in an argument?
- Survival, growth, behavior, and reproduction. These are the four main ways structures help organisms.
- Which structure best supports an argument that a frog can catch moving prey?
- Long, sticky tongue. Specialized for catching fast-moving insects.
- What is the best claim about how a spider web supports survival?
- It traps prey, providing food for the spider. Sticky silk catches insects for food.
- Which option is the best evidence sentence for the claim "Structures support reproduction"?
- Pollen sticks to bees, helping plants make seeds. Shows how a structure directly helps plant reproduction.
- Which option is the best evidence to support the claim that teeth structure affects diet and survival?
- Sharp canines help tear meat; flat molars help grind plants. Tooth shape matches food type for efficient eating.
- What does the term structure mean in life science?
- A body part or feature that helps an organism do a job. Structures are physical parts that perform specific tasks.
- What is the best definition of function when describing a structure?
- The job a structure does for the organism. Function describes how a structure helps the organism.
- Which claim best matches this evidence: "Thick fur helps an animal stay warm in winter"?
- Structures support survival. Fur provides insulation from cold, helping survival.
- Which claim best matches this evidence: "Egg shells protect developing chicks"?
- Structures support reproduction. Shells protect offspring during development.
- Which plant structure supports growth by making food using sunlight?
- Leaves. Photosynthesis in leaves creates food for plant growth.
- What is the best claim about how an egg shell supports reproduction in birds?
- It protects the developing embryo while allowing gas exchange. Hard but porous structure shields developing chick.
- Which claim best matches this evidence: "Seeds have a coat that protects the baby plant"?
- Structures support survival. Protection helps the embryo survive until germination.
- What is the best claim about how a flower supports reproduction in many plants?
- Flowers attract pollinators and help make seeds. Bright colors and scents draw pollinators.
- Which claim best matches this evidence: "A cactus has a thick stem that stores water"?
- Structures support survival. Water storage helps survive dry conditions.
- What is the best definition of function in life science when discussing structures?
- The job a structure does for an organism. Function refers to what a body part does to help the organism.
- Which claim best matches this evidence: "A porcupine has sharp quills that discourage predators"?
- Structures support survival. Quills defend against predators, aiding survival.
- Which structure best supports an argument that a mammal can feed its young after birth?

- Which claim best matches this evidence: "A chameleon changes skin color to blend in"?
- Structures support survival. Camouflage helps avoid predators, aiding survival.
- Identify the structure that best supports survival by reducing water loss in desert plants.
- A waxy leaf coating (cuticle). The cuticle prevents water from escaping in dry environments.
- Which structure supports reproduction by allowing pollen to reach an ovule in flowering plants?
- A flower (including stamens and pistil). Flowers contain reproductive organs for pollination.
- Which claim best matches this evidence: "Roots absorb water and minerals from soil"?
- Structures support growth. Roots help plants grow by providing essential nutrients.
- Identify the structure that supports reproduction by carrying seeds to new places using wind.
- Winged seeds (such as maple samaras). Wings help seeds disperse far from parent plants.
- Which claim best matches this evidence: "A duck has webbed feet that help it swim"?

- Which structure best supports an argument that a plant can grow taller and reach light?
- Stem. Provides vertical support and transport for height.
- Which structure supports survival by helping an owl capture prey at night?
- Large eyes for good night vision. Enhanced vision helps owls hunt in darkness.
- Which structure best supports survival by protecting a turtle from predators?
- A hard shell. The shell acts as armor against predator attacks.
