The diagram below shows the interrelationship between two processes.
arrows pointing in the clockwise direction are shown along a circle. on top of the circle is the label process a and moving clockwise we see an arrow, the label oxygen and glucose, another arrow, the label process b, another arrow, the label carbon dioxide and water, and another arrow point back to process a.
within which organelle do process a and process b occur?
both occur within the mitochondria.
both occur within the chloroplast.
process a occurs within the chloroplast and process b occurs within the mitochondria.
process a occurs within the mitochondria and process b occurs within the chloroplast.

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.
