F214 Communication, Homeostasis and Energy Module 2 Excretion 4.2.1 Excretion a. Define the term excretion Excretion-The removal of metabolic waste from the body which are by products or unwanted substances from cell processes. b. Explain the importance of removing metabolic wastes, including carbon dioxide and nitrogenous waste from the body Carbon dioxide Excess carbon dioxide is toxic and has three main effects: The majority of carbon dioxide is carried in the blood as…

utilize traditional whitener such as chlorine, thereby creating less air and water pollution2. Furthermore, the company have been developing efficient and sustainable energy strategies that not long decrease the cost of manufacture but also creating less environmental destruction. By using most optimized technology, renewable energy source and cogeneration power supply, the company committed high environmental goal and is running at the pioneer role in paper production industry. However, VKP…

James Hardie Building Products revolutionized the siding industry with the introduction of HardiePlank, a fiber cement siding that provides superior resistance to fire and insects. The texture of HardiePlank closely mimics traditional wood siding, and the product is available in a wide range of colors or primed so that homeowners can paint it to match or contrast with the rest of the exterior. Due to its strength, durability and classic appearance, HardiePlank has become the most popular siding…

the volume of water is unable to seep in to the ground efficiently and runoff is created. Runoff is when the water travels across the ground surface and flows in to storm drains, streams, or other direct routes to significant water sources. As researchers May, Horner, Karr, Mar, and Welch state, urban development increases the amount of impervious surfaces which, while it does not contribute to pollution, alters the physical behavior of water systems (May, Horner, Karr, Mar, & Welch, 1997).…

Steps I would take to evaluate the land conditions is to analyze and determine the main causes of the issue at hand by determining the causes of the degrading over overgrazing and invasive weeds that are replacing native grasses. By doing this we can analyze the causes of grazing by ranchers and study how restoring these lands through the restoration process that can be used in order to provide a positive effects and outlook on the environment. Some approaches we can take when evaluating…

The need for agricultural resources is as old as American itself. Since our arrival and birth of our great nation, man has had a need for cheap, durable sustenance that could be produced locally and efficiently. With the expansion of our nation, so has the expansion of supply and demand for agricultural consumer goods, which led to technological advancements to mass produce and shipment. It was not noticed that this drive for agricultural needs would have a devastating impact on the environment…

Fig. 6 shows the results of air permeability, total water absorption, and voids. R mortars had lower permeability than the mortars with WTS. Air permeability of R was 1.13 x 10-13 m², a value 5 times higher than L60. The air permeability increased with increasing WTS content. The water absorption values ranged from 10.6% to 13.7%, and the voids from 9.6% to 12%. The results show that WTS replacement increased the porosity and permeability of geopolymer mortars. The geopolymer binders with WTS…

Background information on the area affected by the disaster: The diseases were first identified in the city of Minamata, Japan in 1956 which is Kumamoto Prefecture in the island of Kyushu and next it was at Niigata City, Niigata Prefecture, Japan. Minamata diseases are a neurological syndrome that results from pollution and environmental contamination. Types of ecosystems: Mercury contamination occurs through aquatic ecosystems in this case of Minamata Japan. Inorganic waste, like mercury,…

The Susquehanna River is home for many: animals, fish and people alike. It is also a key contributor to the Chesapeake Bay, being the largest tributary within the watershed. The pollution of the Susquehanna directly impacts the health of the bay. To understand the importance of the river to the bay, it is necessary to understand what is causing pollution and what solutions can be introduced to lessen the negative impacts. Pennsylvania is a large participant in rural farming as well as urban…
