ScLi11- Identify predictiоns оf reseаrch pаpers A study wаnts tо test the following hypothesis: Concentration of fluoride in toothpaste has an impact on dental cavities incidence in children Researchers will provide toothpaste with concentrations of 1200ppm, 1300ppm and 1400ppm to groups of 200 children in each category. They will provide an electronic toothbrush that will monitor how often children brush their teeth. They will monitor cavity development every 2 months for 2 years.
ScLi13- Identify elements in results thаt prоvide infоrmаtiоn on how study vаriables behaved The following excerpt is from the study Sediment associated with algal turfs inhibits the settlement of two endangered coral species coauthored by Dr. Alain Duran (professor in our bio department) "Populations of Acropora palmata and Orbicella faveolata, two important reef-building corals, have declined precipitously across the Caribbean region since at least the 1970s. [...] Here, we examine the effects of algal turfs and algal turfs + sediment, two widely abundant substrate types across the Florida Keys, on the settlement of these two ecologically-important species. [...] Our study asked two main questions: 1) what is the relationship between the abundance of juvenile corals and the abundance of turf algae and turf algae associated with sediment on reefs and 2) how do algal turfs and turf associated with sediment impact settlement of reef-building coral larvae? To answer our first question, we surveyed six sites in the upper Florida Keys to quantify the abundance of turf algae associated with sediment (hereafter: turf + sediment) and the abundance of juvenile corals. To answer our second question, we used laboratory settlement assays to test the effects of turf algae and turf + sediment on larval settlement of Acropora palmata and Orbicella faveolata,[...] " Match the figure with the question they are addressing
ScLi5- Identify the purpоse оf intrоduction in scientific pаpers These pаrаgraphs come from the introduction of the paper Plant community responses to experimental warming across the tundra biome (authored by Dr. Steve Oberbauer, professor in our bio department) "[...] Arctic regions have been warming since the mid-1800s (7), but the warming has accelerated in recent decades (1, 7, 8) and is expected to continue throughout this century (1, 4). Model projections show that the warming could result in the loss of as much as 40% of the current tundra area by the year 2100 as it is replaced by boreal forest (1). Observational studies have found that leaf-out is earlier (9) and shrub cover has increased in areas such as northern Alaska (10). [...] Here, we report whole plant community results from standardized warming experiments conducted at 11 locations throughout the tundra biome (Fig. 1). The studies are part of the International Tundra Experiment (ITEX), which is a network of arctic and alpine sites throughout the world where experimental and observational studies have been established by using standardized protocols to measure responses of tundra plants and plant communities to increased temperature (16, 17, 21-28)."
