Oscar and Andre used a microscope to observe a sample of pond water and drew an example of each type of organism they saw. Then they compared their drawings. They discovered that their drawings of a euglena and a paramecium were alike, but their amoeba drawings had very different shapes. What are two things that Oscar's amoeba could have been doing that made his drawing look different from Andre's?
