1. What is the purpose of a dichotomous key (not just this key, but any key)? The purpose of dichotomous keys is to figure out the scientific name of organisms or to recognize 2. Why is a dichotomous key called a dichotomous key? 3. Is it possible to create more than one dichotomous key for classifying and identifying the same group of objects? 4. When two people use the same dichotomous key to identify the same object, is it possible (should it be possible) for them to have different final answers? 5. Why are classification and identification important?

Which statements describe dichotomous keys? Check all that apply. A dichotomous key uses characteristics to separate organisms from one another. A dichotomous key uses characteristics to separate organisms into two groups. Dichotomous keys use questions or statements to identify organisms. Dichotomous keys may be created with yes-no questions. Dichotomous keys may have three or more answers for each question or statement.
A dichotomous key is a helpful identification and classification tool. Scientist also use genetics (DNA) to classify organisms? Now that we know a little more about dichotomous keys, which is a more accurate way to classify organisms? Explain.
