Open Ended/Essay Section

Each of the following essay questions is worth 20 pts. You must do all essays.

Take the time to read them and answer each part of the essay that is asked.

Write your answers right under the question.

Open Ended 1: Classification

An expedition has just discovered what looks to be a new species in the artic ice. The leader of the expedition has asked you to go to Antarctica (because you are the leading taxonomist in the world, thanks to Mr. Rose) to verify whether the species is new or was already discovered.

Since it is finals week right now you can not go to Antarctica to help them. Instead, to help them, you are to make a list of 5 questions that will help you get an idea of what the organism is. The questions will be used to classify the organism into one of the 6 kingdoms. After each question, tell why you would ask that question. You are NOT making a Dichotomous Key

Open Ended 2: Evolution

Using your Knowledge of evolution, explain why both predator and prey need each other to survive and evolve. Show the relationships between predators and their prey while explaining your answer.

Be sure to include:

- The predator vs. prey relationship

- How nature will select the traits the surviving animals will

have.

- How the prey and predators will evolve together due to

hunting and hiding on each other.
