Based on the diagram, which statement best compares the life cycles of these two types of organisms?

• Young ladybird beetles take many years to develop into adults. Young grasshoppers develop into adults quickly.

• Young grasshoppers live in a habitat that is different from that of adults. Young ladybird beetles live in the same habitat as adults.

• Young grasshoppers undergo incomplete metamorphosis to become adults. Young ladybird beetles undergo complete metamorphosis to become adults.

• Young ladybird beetles have a nymph stage before becoming adults. Young grasshoppers are larvae before becoming adults.

• A Conduct five trials, using a different scale to pull each block of wood

• B Conduct five trials, pulling a different side of each block each time

• C Conduct five trials, using a different table for each trial

• D Conduct five trials, pulling each block of wood in the same way for each trial

• F Heat from the sun warms the ocean, causing water to evaporate. The water vapor then condenses to form a cumulonimbus cloud.

• G Heat from the sun causes clouds in the area to gather over the ocean and form one large cumulonimbus cloud.

• G Heat from the sun causes clouds in the area togather over the ocean and form one large cumulonimbus cloud.

• J Light from the sun causes ocean water to reflect water vapor into the air and gather over the ocean into a cumulonimbus cloud.

• A Stir the liquids, let them settle, and then identify the bottom layer as water

• B Drop a piece of ice into the graduated cylinder, let the ice settle, and then identify the layer just above the ice as water

• C Add water to the graduated cylinder, let the mixture settle, and then identify the layer that increases in volume as water

• D Carefully pour each layer into separate plastic containers, place the containers in a freezer, and then identify the liquid that takes the longest to freeze as water
