As the demand for mobile computing and all-electric cars increases, the limitations of current battery technology presents a roadblock. Invented in the 1790s by Italian physicist Alessandro Volta, the electric battery has been the workhorse of numerous gadgets, devices, and machines. As consumer devices have become smaller and their uninterrupted use before recharging more important, it has also become increasingly important for batteries to become both miniaturized and more energy efficient. This

battery is an equipment or device that accumulates chemical energy and makes it accessible in electrical form. It is an integration of one or more voltaic cells, each of which is composed of two half cells connected in series by the conductive electrolyte. I have chosen to investigate and conduct my research project with two different cells namely-Duracell and Energizer .I have chosen these two because they’re the most popular and recommended cells globally .Duracell works for a maximum of 7 hours

Body fluid compartment and water balance The human body fluids are divided two major fluid compartments. Fluid compartments are mainly used to compare the situation. It is the intracellular and extracellular fluid. These two fluid compartments are account for total body water. The two main parts of the body fluids are watered and make up the body's tissues. Fluid compartments are a location relative to the membrane of the cells. The intracellular fluid system includes all fluids in cells plasma membrane

are thus capable of producing an electric current and are called electrolytes. The amount of electricity produced is directly proportional to the concentration of ions in solution. With regard to electrolytes we have learned previously that strong acids and strong bases ionize completely, and are therefore strong electrolytes because they produce a large electric current. Soluble salts are the other type of strong electrolytes. We also learned that weak acids and weak bases ionize only partially

Homeostasis Homeostasis can be defined as the body's ability to maintain a regular internal environment. This is done by maintaining a body temperature within a certain field. An internal environment means the environment inside an organism. Negative feedback ensures that, in any control system, changes are reversed and returned back to the set level. The negative feedback keeps our body temperature at a constant 37°C. If we get too hot, blood vessels in our skin vasodilate (become larger) and

athletes often crave on their meals when their bodies sodium levels are low. It is vital to maintain the sodium level to ensure that the fluids in athlete’s bodies are sent to the correct places and used effectively. When athletes train a water or electrolyte fluid is needed to ensure they do not become dehydrated. At the same time athletes must make sure they do not over hydrate. Both dehydration and overhydrating can cause a loss or excess of sodium and therefore muscle cramping. This research task

Case Study for Final Exam Myasthenia gravis is a chronic autoimmune neuromuscular disease characterized by varying degrees of weakness of the skeletal (voluntary) muscles of the body. The name myasthenia gravis, which is Latin and Greek in origin, literally means "grave muscle weakness." With current therapies, however, most cases of myasthenia gravis are not as "grave" as the name implies. In fact, for the majority of individuals with myasthenia gravis

blood in the efferent arteriole will eventually exit the kidney via the renal vein. The renal vein is responsible for sending filtered blood back in circulation. Before leaving the kidney, the efferent arteriole will release and absorb minerals and electrolytes due to the close proximity to the loop of Henle. This is regulated by hormones, the body’s level of dehydration, and blood osmolality. After a brief overview of the anatomy and physiology of the kidney, we can go into further detail regarding
