treatment of brackish (i.e. contain dissolved salts) water supplies. Distillation is one of many processes that can be used for water purification and can use any heating source. Solar energy is a low tech option. In this process, water is evaporated, using the energy of the sun then the vapour condenses as pure water.This process removes salts and other impurities. Solar distillation is used to produce drinking water or to produce pure water for lead acid batteries, laboratories, hospitals and

dairy carbon footprint study, it showed that carbon footprint of a gallon of milk is approximately 17.6 pounds of carbon dioxide equivalents. This will usually occur during milk freight and distribution. * Water pollution-Disposal of organic wastes without treatment leads to pollution of water resources hence, causing a rapid growth of microscopic algae that kill fishes and other aquatic life. Furthermore, ammonia released from manure can lease to acid rain causing environmental harm. * Land

conclusion of the more pollution, the more the world’s temperature increases but this is all about to change. Global cooling is caused by Global Warming heating up the world and melting the ice caps. The ice caps then release fresh water, which now dilutes into the Arctic waters making it less salty. This means the Gulf Stream will no longer sink to the ocean floor and will not make its return journey to the Gulf of Mexico. As soon as the Gulf Stream switches off there is no warm air reaching the Artic

is for plants who can handle cold weathers. It is said in the article that Plant physiologists have focused on sensory systems and turgor- dependent movements that control the aperture of stomata and influence the conductance to diffusion of water vapor across the epidermis. So it somewhat stated that it focused only on such systems and movements. It didn’t entirely focus on the Plant’s components. One more thing, I can reflect that based on my readings about the article, as observed by

VARIETY OF RESOURCES ON EARTH THE DIFFERENT RESOURCES ON EARTH Human beings, animals and plants need food, water, air and shelter in order to survive. The Earth has the resources needed to sustain life. The resources are air, water, soil, minerals, fossil fuels and living things. Air is needed by all living things to survive. The atmosphere is a layer of air that envelops the Earth. Air is a mixture of gases. Air

lake is under threat from eutrophication that can severely affect the aquatic life living in it and the surrounding vegetation. It has been estimated that there has been changes in the populations of the various aquatic animals living in the lake’s waters. Zooplankton population has faced the greatest changes. The lake experiences winter and summer seasons with full might. Temperatures can go as high as 25.9 degrees Celsius in the summer and as low as sub-zero in the winter. The vegetation

spill over him like a faucet left running (line 62.) like the snow is melting, like his cold and snowy heart. Issy was like fire to him, and he burns himself when he ruins his relationship whit Laurel, it is also why she is killed in a pool, because water kills fire. The Title which is “Save as Many as You Ruin”, maybe means that he saved Lucy, when he ruined his relationship with Laurel, so when he left the love in his life, he got a new one, who is Lucy. And Issy is the one who ruins Laurel and

swam in the ocean water can related to the difference in fresh and salt water. Children visit the beach often and will relate to the difference of the water in a pool and beach water. Besides the difference in taste we will explore the buoyancy force of salt water, which allows things to float with greater ease than is possible in fresh or pool water. Children will also learn that ships also are known to ride higher in salt water than in fresh water. The buoyant force of salt water can be demonstrated

Potassium Permanganate Abstract The glass tube and the agar-water gel test. In the glass tube test, two cotton balls were soaked in two ends of the glass tube. Ammonia (NH3), with the lighter molecular weight value diffused at a faster rate. Thus, resulting in the formation of a white smoke in the glass tube moving closer to the side of the heavier substance Hydrochloric Acid (HCl). The agar-water gel set-up consisted of a agar-water gel in a petri dish. Potassium Permanganate (KmnO4), Methylene
