Seems like an open ended question, the habitat organ was the ocean, more specifically is probably the sea floor, since that it is where sponges (basal animals) live
<span>Cells that have differentiated still have most of their genes and they </span><span>can still express those genes.

Independent variable is the one that can be changed to test the prediction.
<u>Explanation:</u>
In order to test the prediction in an experiment, the independent variables are always changed. This is because the independent variable are the one that is always produces different cause and effect in an experiment.
They are not dependent on the outcome of the experiment but can alter the experiment to any extend when they are altered. Hence we can conclude independent variable as right answer.
