Tucker and Micayla are conducting an experiment with cellular respiration. The purpose of their experiment is to find out if plant cells utilize cellular respiration in addition to photosynthesis. They begin by filling one test tube with glass beads, one with dried (non-germinating) peas,
and one with peas that have been soaked and have begun to germinate.

Which statements best describe the differences or similarities between a comparative investigation and an experimental investigation? check all that apply. experimental investigations are best for showing cause-and-effect relationships, while comparative investigations do not necessarily show this type of relationship. comparative investigations are often impractical and unrealistic, while experimental investigations are the most practical and realistic kinds of investigations. comparative investigations allow for the use of a wide range of variables but do not have a control group, while experimental investigations involve variables that can be controlled. both experimental investigations and comparative investigations are designed to answer scientific questions. both experimental investigations and comparative investigations focus on making observations rather than collecting new data.
