Introduction: The purpose of the two lab experiments conducted in this study was to observe the temperature preference of Tenebrio molitor, commonly known as mealworm beetles. Specifically, their preference for room temperature or cold/warm temperature. In addition, the independent variable in this experiment is the temperature of the environment (room temperature, cold, or warm). The dependent variable is the temperature preference of the mealworm beetles. Furthermore, the null hypothesis for both experiments was that the temperature of the chambers would not have a significant impact on the amount of time the beetle spent in either chamber. Then the alternative hypothesis for both experiments was that the temperature of the chambers will have a significant impact on the amount of time the beetle spends between the two chambers. Moreover, mealworm beetles prefer dark environments because they have a negative phototactic response, meaning the mealworm beetles are attracted to darkness and seek out areas with lower levels of light. This behavior may be a result of the beetles' natural habitat, which is typically underground or in dark, sheltered areas such as burrows or rotten logs (Balfour & Carmichael, 1928). Dark environments provide mealworm beetles with protection from predators and help regulate their body temperature and moisture levels (Balfour & Carmichael, 1928). It is also found that mealworm beetles exhibit a strong humidity preference and are more likely to move toward areas of higher humidity, which are often found in dark, sheltered environments. This preference for darkness may also be linked to their natural behavior of seeking out dark, damp places to lay eggs and protect their offspring (Gunn & Pielou, 1940). Introduction: Explain your results in terms of purpose. Try to address each of the following: 1. Evolution: explain how evolutionary principles apply to beetle diversity and adaptation, identifying specific traits that have evolved in response to environmental pressures. 2. Structure and Function: describe various beetle anatomical features and their roles in survival, reproduction, or behavior. 3. Information Flow, Exchange, and Storage: investigate how beetles communicate, perceive their environment, or store genetic information, linking these processes to their survival and reproduction. 4. Pathways and Transformations of Energy and Matter: explore how beetles obtain, use, and store energy, discussing the implications of these processes for beetle ecology and conservation. 5. Systems: considering interactions between beetles, their environment, and other organisms.
