Explain why the absence of water halts photosynthesis

1. If you don’t water a plant, it will eventually die. Explain why the absence of water halts photosynthesis. Also, cells that use aerobic cellular respiration, like humans, do not produce ATP at normal levels without oxygen gas. Discuss why this is so. (two scholarly sources)

2.  Genetically modified organisms (GMOs) are used to create human growth hormone, insulin and clotting factor proteins that are used to treat dwarfism, diabetes and hemophilia respectively. Several crops such as corn and soybean have also been genetically modified in order to facilitate either the management or growth of these crops. Why do you think there is push back or opposition against the use of GM food crops but not in the use of products such as insulin, which is also created using GMOs? (two scholarly sources)

3. Do you think it is important that all species be prevented from going extinct? Explain your reasoning. Also, there is a process called “extinction” where scientist use DNA from an extinct species and genetically “recreate” that species. Do you think this is a good idea? Explain you reasoning.(two scholarly sources)
