INTRODUCTION Gas exchange is the movement of respiratory gases across a membrane through diffusion. Diffusion is the process of which the respiratory gases across the gas exchange membrane (oxygen from the environment into the body‚ carbon dioxide from the body to the environment). Using the concentration gradient along the gas exchange surface. For gas exchange to occur these three Features are needed; the gas exchange surface needs to be moist so that the oxygen and carbon dioxide can dissolve

Ocean acidification is the ongoing decrease in the pH of the Earth’s oceans‚ caused by carbon dioxide from the atmosphere‚ Seawater is slightly basic (meaning pH > 7)‚ and the process is a shift towards pH-neutral conditions rather than a transition to acidic conditions (pH < 7). Ocean alkalinity is not changed by the process‚ or may increase over long time periods due to carbonate dissolution. An estimated 30–40% of the carbon dioxide from human activity released into the atmosphere dissolves into

function p(t) = −log10t. The variable t represents the amount of hydronium ions; p(t) gives the resulting pH level. Water at 25 degrees Celsius has a pH of 7. Anything that has a pH less than 7 is called acidic‚ a pH above 7 is basic‚ or alkaline. Seawater has a pH just more than 8‚ whereas lemonade has a pH of approximately 3. 1) Create a graph of the pH function either by hand or using technology. Locate on your graph where the pH value is 0 and where it is 1. When y=0 x=1; when y=1 x=0.1 (1‚0)

Global Water Treatment Products Market 2014-2018 Water treatment products are various products that assist in removing the impurities in water. Various types of water such as seawater‚ ground water‚ municipal drinking water‚ and wastewater can be treated using water treatment products. The wide variety of applications for water treatment products is one of the major reasons for the increase in the demand for these products. Water treatment technologies are used to remove or destroy pesticide active

Abrasion occurs when this material is hurled against cliffs as waves hit them‚ wearing the cliff away. | Coastal Transport | Description | Solution | Minerals are dissolved in seawater and carried in solution. The load is not visible. Load can come from cliffs made from chalk or limestone‚ and calcium carbonate is carried along in solution. | Suspension | Small particles are carried in water‚ e.g. silts and clays‚ which can make

Fukushima in 2011 is the worst miserable thing that happened in the past‚ and this disaster have leaked significant amounts of radiation that have affected ecosystems in the region. On March 21‚ 2011‚ TEPCO (Tokyo Electric Power Company) investigated the seawater near the southern discharge port of the Fukushima Daiichi NPS‚ revealed that radioactive substances significantly exceeding safety standard values were detected.

What causes ASS? ASS are any material or sediment that contains iron sulfides that‚ when disturbed or drained‚ forms sulfuric acid. In most cases‚ the iron sulfide present is pyrite (FeS2‚ also known as Iron (IV) Sulfide). This pyrite is very reactive. It is usually the smaller crystals of pyrite found in ASS. The pyrite reacts with oxygen to create sulphuric acid (therefore disturbing the soil creates the acid‚ as the pyrite is exposed to the air). The smaller pyrite framboids (raspberry shaped
