Directions for the Game: #1. Mini- white boards can be used to have the teams write their answers. After they have their answers hold the board up for the teacher to see. #2. Write your team number on top of your board. #3. Every team that answers the question correctly gets the points, however, the first team that answers correctly gets control of the board. #4. Start every category at 100 points and work you’re way down to 500 points. #5. Click categories at the bottom of each slide to take you back to the categories page.

West Indian manatees are large, slow-moving aquatic mammals that make their home in the rivers of Florida. Hundreds are killed each year by watercraft, and the habitat of these animals in Florida is threatened. Scientists and conservationists interested in saving this animal from extinction have been studying the manatee and have found very little genetic variation among the remaining populations. Why is this a cause for concern? A. It is not a cause for concern. Only the fittest will survive to pass on their genes. B. Lack of genetic variation will lessen the ability of the manatee to be trained. C. It is more difficult to clone organisms that do not express genetic variation. D. Genetic diversity is necessary to adapt to changing environments and react to disease. Categories

D. Genetic diversity is necessary to adapt to changing environments and react to disease. Categories
