ScLi5- Identify the purpоse оf intrоduction in scientific pаpers The following pаrаgraphs belong to the introduction of A comparative examination of odontogenic gene expression in both toothed and toothless amniotes. In this study, Dr. Lainoff (professor in our Bio department) and colleagues investigated the genetic underpinnings of the lack of teeth in turtles. "Two key problems at the intersection of evolutionary and developmental biology are how complex organs such as teeth are formed and how variable morphology is generated. One method for identifying unknown components of complex genetic pathways is to investigate examples in nature where development has been disrupted. Despite the strong selective pressure on teeth, several vertebrates have lost their dentitions during evolution, including birds, baleen whales, anteaters, several lineages of fish, and turtles. Discrepancies in genetic pathways or in developmental timing between toothed taxa and toothless taxa can be used as tools for identifying aberrant changes linked to tooth agenesis. [...] Studies conducted in mouse models suggest that the position where teeth will develop is established by the interactions of two mutually antagonistic signaling molecules, FGF8 and BMP4 (Neubüser et al., 1997). Early in development, the oral epithelium of the mouse mandible is broadly divided into two domains: Fgf8 and Fgf9 mark the proximal (lateral) region, defining the presumptive molar field, while Bmp4 marks the distal (mesial) area, delineating the presumptive incisor field (Åberg et al., 1997; Kettunen and Thesleff, 1998). [...] In this study, we first investigate potential mechanisms underlying the loss of teeth in turtles during evolution by examining the red-eared slider turtle, Trachemys scripta elegans, for histological and molecular evidence of tooth development. Additionally, we take a preliminary step towards addressing whether the antagonistic initiation of tooth development by BMP4 and FGF8 is conserved across amniotes, as well as whether limited Bmp4 expression is a good indicator of subsequent tooth loss, by determining whether Bmp4, Msx1, Msx2, and Fgf8 expression is conserved in an edentate reptile (T. scripta), a toothed reptile (the American alligator, Alligator mississippiensis), and a toothed non-placental mammal (the gray short-tailed opossum, Monodelphis domestica) during developmental stages equivalent to embryonic stage 10.5 (E10.5) in mice."

ScLi-7 Identify hypоtheses аnd оbjectives in scientific pаpers The fоllowing is а hypothetical study in STEM education. Current research in STEM education is focusing on strategies to improve student engagement and learning outcomes in science, technology, engineering, and mathematics. While traditional teaching methods have relied heavily on lectures and standardized testing, recent studies highlight the effectiveness of active learning, project-based learning, and the integration of technology in the classroom. However, there remains a significant gap in understanding how these innovative teaching methods impact different student demographics, including underrepresented minorities and women in STEM fields. Furthermore, the long-term effects of these educational strategies on students' career choices and success in STEM careers are not well understood. Addressing these gaps is crucial for developing more inclusive and effective STEM education practices. What is the most likely hypothesis of the study?
