Questions 12 - 14 refer to the following scenario. Write your answers to the questions in the

space provided. (1 point each)

The Blob from Planet XImagine that you are watching the "Blob from Planet X" in a movie theater. The Blob

mysteriously appears one night out of a lake on the edge of town. As it begins to move toward the town, it eats trees, cars, and even buildings! Nothing seems to be able to stop the Blob! Fire does not burn it, but it does cause it to retreat back toward the lake. Finally, as the sun begins to rise in the morning, the Blob disappears back into the lake. Everybody hopes that it will not reappear, but the next night it is back, swallowing up more cars and buildings. Finally, the hero of the movie manages to cut the Blob in half. But, now there are two Blobs! The next morning, both Blobs disappear back into the lake.

Scientists work frantically the next day. They must find a way to stop the Blob. They compare the Blob with living things to try to discover what the Blob really is. You must help the scientists find out if the Blob really is a living thing.

_____ 12. Give one characteristic of life that the Blob has (based on the scenario).

_____ 13. Based on the scenario, give one reason that the Blob is not living.

_____ 14. As a biologist, describe a test/experiment that you could do in the lab to prove that

the Blob was a living thing? (Be specific!)
