Microbial Fuel Cells (MFCs) which capable of harvesting electricity from renewable biomass and organic wastes arise as a promising yet challenging candidate to the existing sustainable energy portfolio (Picioreanu‚ et al. 2010). II. Historical Overview of Microbial Fuel Cells The idea of extracting energy from organic matters through the catalytic reactions of microorganisms emerged a century

Sickle Cell Anemia Sickle cell anemia is an inherited blood disorder‚ identified by the sickle shape of red blood cells which carry less oxygen and break easily‚ causing anemia. The sickling trait‚ the less serious form‚ occurs from the inheritance of only one parent; however‚ both parents must exhibit the disease in order for full symptoms to take place. It is caused by an error in the gene that tells the body how to make hemoglobin. The disorder is usually found in people of African descent

Are Cell Phones Dangerous? Are cell phones dangerous? Cell phones are dangerous because of many reasons. One reason that cell phones can be dangerous is because if the GPS is on‚ then people can track someone just by the GPS being on. When the GPS is on the predators act like police and know how to track people by the GPS‚ also by photo posts especially when the post is on the photo map. A photo map is used to see where a picture was taken. The next reason why cell phones can be dangerous

Do you like to look up stuff on your cell phone? I think cell phones should not be used in class because of distractions‚ Students will text in class and then cell phones keep kids from their work. First reason I disagree with cell phones in class in because they might distract students from doing there work in class then if that happens then the students is grades are going to go down and cell phones might make students fail there class if they ain’t going to do there work and just text

Cells and Movement of Substances All living things are formed by cells‚ the structure of these cells varying depending on their function. Animal and plant cells have common features such as a nucleus‚ cytoplasm and cell membrane. Dissolved substances pass into and out of cells by diffusion Diffusion Diffusion definition: Diffusion is the movement of molecules from a high concentration to a low concentration. Dissolved

After reading the “‘Bubble baby’ stem cell” paper I have come to the conclusion that stem cell research is an excellent thing. The reason why I think that is if we never do research and create a cure for “Bubble baby disease” then we will continue to lose babies. But‚ if we risk a few lives of babies for research in the long run it will save millions if not billions of lives. In this essay I will give three reasons on why I think stem cell research is a great thing. “Bubble baby disease.” In my

Besides‚ cell phone prices were became more affordable than the first generation. At that time‚ the cell phone industry was beginning to take off. The Third Generation or 3G‚ is what we currently use today. This technology is not only capable of transferring voice data (phone call)‚ but also able to transfer

Impact of Technology on Cell Theory Technology has had a profound impact on the development of cell theory‚ allowing scientists to view the components of organisms on an unprecedentedly small scale. Before the creation of microscopes‚ misconceptions about how organisms were originated arose. The idea of spontaneous generation‚ a theory held for nearly two millennia‚ proposed that organisms originated from inorganic matter. The lack of technology impeded on the development of cell theory‚ until the creation
