- 102Topic: NATURAL SELECTION ACTIVITY Simulate a case of natural selection in a predator-prey situation. STEP 1 Gather your materials. You should have: . 1 fork, 1 knife, 1 spoon, and a length of tape (each will be used toestablish the distinct predator "feeding apparatuses")· 4 cups (each will serve as a distinct predator's "mouth")· 3 types of prey (such as popcorn, macaroni, and kidney beans)· 1 clearly delineated habitat (such as a table, a box, or a roped-off areaof ground). 1 timer that allows for counting by seconds (such as a watch or cellphone) STEP 2 Set up the predators. There is variation in predatory feeding apparatuses in this population. You will choose one of the available predator feeding apparatuses: fork, spoon, knife, or four fingers (with your thumb taped to your hand so that you cannot use it). You will also take a cup, which will represent the predator's mouth. Your goal will be to use your feeding apparatus to collect food and put it inyour mouth. STEP 3 Set up the…1 Fri Mar 1 to C 1 hp + Writing Task: Citing the supplied documents and using your knowledge of natural selection, complete the following tasks. Explain what genetic variation is and how is it beneficial to a population facing an environmental challenge Engage in argument from evidence whether small or large body size is more fit for survival in the fish populations. Predict what is likely to happen to body size for fish harvested by nets if the holes in the nets were to become smaller 10% Done

The researchers looked at a fish's willingness to explore a new environment, which they called boldness. A more bold fish is one that will readily explore when placed in a new setting. Their study considers if boldness may be an adaptive trait, that is, subject to natural selection. The researchers therefore looked at the correlation between parent and offspring boldness scores, as shown in the figure. A. What pattern is illustrated by this figure? What factor(s) necessary for natural selection are shown in this graph? The association between the boldness scores OF Parents & Children is depicted in the image.

The Grants' study on the island of Daphne Major studied what organisms? 3. Where did the 13 species of finches on the islands come from? 4. How did the Grants catch the finches? 5. What features did they measure? 6. What happened in 1977 to the island? 7. What type of birds were more likely to survive after this event? 8. After the El Nino event in 1983, which birds were more likely to survive? 9. What keeps different species from mating on the Galapagos islands? 10. The most likely scenario explaining the different finches on the islands is that: a) different birds migrated to different islands b) one species evolved into many different species 11.
