This means the object has behaviours attached to it.

You can see these on the object properties tab for Qualifiers and Behaviours. Behaviours are events which can be attached to objects, and run for every instance of the object individually. So, for example, if you have a behaviour to add 1 to a global value, on an object which has 20 duplicates, your global value willnend up at +20. Similarly if you set an alterable value of the object with a behavior to a random number, each duplicate will get its own random number, rather than having to loop through all of the duplicates one by one in the main events.
