(you can trust my answers if YOU want too)
-coconut
coconut is right but some of the questions are changed.
10. During which phase of Celluar Resperation is Carbon Dioxide released? (Krebs Cycle)
12. How many glucose molecules can undergo cellular resperaation when 13 O2 molecules are available to react? (2)
15. Which activity uses ATP to lower body temperature? (panting)
100% correct, thanks again coconut!
thank you so much coconut again you are a grade saver
also if u have nevada conecctions, #8=electrolysis
So the conclusion I've come to is to 100% trust coconut

Does someone have the answers for the short essay questions? Here are the questions...
1. Plants in different environments have challenges that only they have. For example, the growth of a plant in a rain forest (e.g., an orchid) might be more affected by different things than a plant in a desert (e.g., a succulent). In three to five sentences, compare environmental challenges that could affect the photosynthetic process of a rain forest plant versus a desert plant.
2. In 3 to 5 sentences, describe the relationship between a glucose molecule and the products it makes during cellular respiration.
3. Remember the law of conservation of mass. The human body uses cellular respiration to make energy. Using the chemical equation for cellular respiration, explain how the amounts of oxygen and carbon dioxide inhaled by the lungs is different from the amounts exhaled. Explain your answer in 1-2 sentences.
4. Dragonflies are flying insects. In the summer, dragonflies can be seen perched on tree branches in an obelisk pose (i.e., a handstand position with the tip of their abdomen pointing upward). In 3–5 sentences, describe how dragonflies might control their body temperature and give reasons for why they might perch in this pose.
