While observing some ants, a group of German scientists noticed that the ants had an excellent sense of distance. Wondering how
this was possible, they decided to perform an experiment. First, the scientists taught ants to retrieve food from a feeder placed near the ants' home. Then, they removed the lower portion of some of the ants' legs to make them shorter. They also attached tiny stilts to some of the other ants' legs to make them longer. Finally, the scientists watched the altered ants attempt to retrieve food from the feeder. After several trials, the scientists found that the ants with shortened legs walked toward the feeder but stopped short of it. On the other hand, the ants with lengthened legs walked past the feeder. Which of the following conclusions can be made given this information? A. Altering an ant's leg length has no effect.
B. The ants on stilts were more off balance than other ants.
C. The ants were no longer interested in the food.
D. Ants count their steps while walking.
The answer would be D, that ants count their steps whole walking, because the amount of steps are either longer or shorter depending on whether the ant has stilts or not, and this is caused by the ants counting their steps.
The conclusion is that the ants counts their steps while walking and because of this there was no difference in the number of steps they walked.
The ants with smaller legs stopped before food and the ants with larger legs moved ahead from food.
The study and the experiment shows that the ants count their steps while moving forward. They track the path of other members that move forward them by counting steps.
