Electrolyte is a scientific term for salts‚ specifically ions. The term electrolyte means that this ion is electrically-charged and moves to either a negative or positive electrode. Ions that move to the negative which are called cations are positively charged and Ions that move to the positive which are called anions are negatively charged. They can be divided into acids‚ bases‚ and salts‚ because they all give ions when dissolved in water. Electrolytes are present in the human body‚ and the balance

ENVIRONMENTAL ISSUES IN DAIRY PROCESSING The dairy industry handles large volumes of milk‚ and the major waste material from processing is the water. The water removed from the milk can contain considerable amounts of organic milk products and minerals. In addition cleaning of plant results in caustic wastewater. This article discusses the impact wastewater would have if released in the environment‚ methods to minimise the amount of both the organic and inorganic material in the wastewater

The rise of toxic Microcystis algae blooms in Lake Eerie A combination of climate change and agricultural practices have led to an excess run off of phosphorus in Lake Erie‚ resulting in excess algae blooms spread across the surface of the water. Phosphorus is the key nutrient that dictates algae growth and abundance. Microcystis‚ a species of cyanobacteria characterized by its blue colour continually contaminates the waters‚ and damages marine ecosystems‚ due to its toxicity. Being the smallest

nutrition. One disease young children are at risk for is rickets. Rickets is caused by a vitamin D‚ calcium‚ and phosphorus deficiency. Rickets is the softening and weakening of the bones in children. Skeletal deformities and fractures can occur because the bones are so soft and weak. Rickets is seen during periods of rapid growth because during growth a great deal of vitamin D‚ phosphorus‚ and calcium are needed. “The predominant cause is a vitamin D deficiency‚ but lack of adequate calcium in the

phosphates are the key to the activity of ATP. The Phosphorus Cycle The fact that ATP is Nature’s ’universal energy store’ explains why phosphates are a vital ingredient in the diets of all living things. Modern fertilizers often contain phosphorus compounds that have been extracted from animal bones. These compounds are used by plants to make ATP. We then eat the plants‚ metabolise their phosphorus‚ and produce our own ATP. When we die‚ our phosphorus goes back into the ecosystem to begin the cycle

Another benefit of phosphorus and nitrate is that they improve fertility. Phosphorus and nitrate are both key elements to fertilizer. Phosphorus is needed for plant growth. Phosphorus makes plants grow faster and stronger. This helps farmers to
