write the introduction of my biology report

Write your introduction as three connected paragraphs that follow a funnel structure, starting broad and becoming more specific. Begin by introducing the general issue of global warming and why temperature is important for ectothermic organisms, then explain key concepts like thermal tolerance, acclimation, and CTMax to establish background knowledge. In the second paragraph, summarize what previous studies have found about acclimation and thermal tolerance, including mechanisms like heat shock proteins, and identify the research gap by explaining what is still unknown about short-term acclimation. In the final paragraph, narrow the focus to your specific study by introducing the crayfish and describing the experimental setup, then clearly state your research question and hypothesis using We hypothesize that. Throughout the introduction, write in past tense, avoid direct quotes, and include a total of five properly formatted citations.
