ScLi12- Identify the elements in the methods that allow researchers answer their research question A real study aimed to test whether the pattern of resource distribution in an environment affected the number of individuals of a certain species that can be maintained by that environment. Researchers used single-strain populations of budding yeast (microorganism that you use to raise dough) in plates with the amino acid tryptophan (Trp) as the exploited, renewable resource. Researchers set plates with Trp in order to manipulate the supply of the limiting resource. 96 plates were tested. Each plate was divided in 12 sections. Each plate had either a heterogeneous or homogeneous distribution of resources (Trp). A heterogeneous environment was designed by alternating high and low Trp concentrations. A homogeneous environment was designed as having a uniform amount of Trp in all 12 sections. Yeast abundance in each well was quantified every 24 h.
