Problem: Relying on an animal to come by is risky. A flower may have to wait a long time for the right animals to come by. What if one never passes close enough to the flower? Hoping the wind will blow is also risky for a plant. What if the wind does not blow? What if the blowing pollen does not land on another flower? The wind could even blow the pollen over the ocean where it is wasted. Giving free nectar is costly. It is not a good use of the plants energy. A plant uses a lot of energy to produce nectar. Some animals may just drink the nectar. They may not carry off any pollen in return. To improve their chances, plants evolved special traits. For example, they developed ways to hide their nectar. Only certain animals were able to get at the plants hidden nectar. These specific animals might be more likely to visit only flowers of the same species. This was also a benefit for some animals. Animals also evolved special traits to get to the nectar.

Question: "What problems could arise if a plant waits for the wind to help it?"

Answer: "The plant might be crushed"

Problem: Captured Moments by Will Shetterly I remember Papa's stopbox, a teal blue Tiempo Capturado that Mama brought home for his birthday. It was huge and inefficient, and she should never have spent so many pesos on a toy, but Papa would not let her return it. He used it to preserve baby tomatoes, cucumbers, and strawberries in translucent cubes that he stored in the pantry for spring-time meals in the middle of winter. Mama kept her mink jacket, a family hand-me-down, safe from time in a stopbox, and lent the capturador to my uncle for his stamp collection. Sometimes they would let us little ones to seal a treasured toy or a last piece of birthday cake until we begged them for its release, usually a few hours after enclosing it. When my father died, a year after my mother, my sisters and I cleaned out their apartment. We found our baby shoes protected in stopboxes. I took mine home, where they sat above my computer while I worked on my first play. One night when I did not believe love had ever existed for anyone, I used my own capturador, a sleek titanium Sanyo Tardar Ahora, to undo the stopbox. Bringing my face close to the shoes, I breathed deeply of air that my parents had trapped while closing up that symbol of their love for me. The instant would have been improved had my baby shoes been cleaned before they were encased. But as soon as I coughed, I laughed, and I did not try to kill myself that night.

Question: "What sat on the computer?"

Answer: "Stopboxes"

Problem: Earth processes have not changed over time. The way things happen now is the same way things happened in the past. Mountains grow and mountains slowly wear away. The same process is at work the same as it was billions of years ago. As the environment changes, living creatures adapt. They change over time. Some organisms may not be able to adapt. They become extinct. Becoming extinct means they die out completely. Some geologists study the history of the Earth. They want to learn about Earths past. They use clues from rocks and fossils. They use these clues to make sense of events. The goal is to place things in the order they happened. They also want to know how long it took for those events to happen.
