Answer:
Comparative and experimental investigations are investigations which are performed to address the questions of natural phenomena. Both of these investigations follow scientific procedures.
Comparative investigation refers to the type of scientific investigation, in which two or more object, organisms or features are compared under different conditions such as temperatures, times of year and locations. In this investigation process control group is not used. It is a comparison based study. Experimental investigation refers to the investigation in which the variables can be changed and manipulated in order to determine the effect of such condition only on a single object, feature or organism. In this investigation is a control group is used. Independent and dependent variables are used in both type of investigations. Experimental investigation derives the relation of two or more variables. Independent variables are those, which can be changed and manipulated in an experiment to show it's effect on the dependent variable.
On the basis of the above information, the similarities and differences between the comparative and experimental investigation can be described as follows:
Experimental investigations are best for showing cause-and-effect relationships, while comparative investigations do not necessarily show this type of relationship.: This describes the difference between the two 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.:This describes the difference between the two investigations.
Both experimental investigations and comparative investigations are designed to answer scientific questions.:This describes the similarity between the two investigations.

Explanation
The process of mitosis generates new cells that are genetically identical to each other. Mitosis helps organisms grow in size and repair damaged tissue. Some species of algae are capable of growing very quickly.
