Plants and other multicellular organisms through the process of photosynthesis
A heterogeneous mixture composes of non- uniform components, so the concrete would be the answer, because you can tell the components from one another.
Mono or root systems have fibrous roots These fibrous roots occupy the upper level of the soil in comparison to dicot root structures that dig deeper and create thicker systems.
A disadvantage is that this type of root is not favourable to the water scarce area or drought. So such plants live in the areas where water is easily available.

evolution of populations over time
You should pick both colonies for the further analysis. Colonies are white or blue depending on their possibility to metabolize X-gal product (the blue colonies can metabolize X-gal product, and they encode for lacZgene). Whether it encodes or lacks the lacZ gene, it can still uptake the antithrombin gene and grow on the medium through electroporation.
