dichotomous keys are most often used for identifying plants and animal species based on their characteristics
|
|
the use of dichotomous keys can sometimes experience errors because closely related species may share many of the same characteristics
|

In this round I am going to be presenting you with statements. When you receive a statement, please consider the statement very carefully and let me know whether it's true or false. If you are right, two points. If you are incorrect you lose a precious point. You may choose not to respond in which case that statement becomes available to the two other schools. A school may ring and attempt an answer if
