Water is also involved in many chemical reactions in our body, without it our body cannot function. Everyone and everything needs water to survive. Water is our most important resource that is required to ensure our survival. This resource is something that we use every day in our lives and it serves many different purposes. We use water to take showers, to flush the toilet, cook dinner, to drink, and to clean. It is used in agriculture, industries, transportation, and as an alternative energy source (eg electricity).
Some plants and fish are made up of 90% of water. There are many reasons why water is important to all living organisms. Metabolic role of water -Hydrolysis: Hydrolysis is the reaction of a compound with water,usually resulting in the formation of one or more new compounds. Hydrolysis is an important reaction in plants and animals. The action of certain enzymes allows the hydrolysis of proteins, fats, oils, and carbohydrates. Medium for chemical reactions: All chemical reactions take place in some kind of liquid medium.
Diffusion and Osmosis: Water is necessary for osmosis and diffusion to take place through surfaces, for example in the lungs with oxygen. Photosynthesis: Water is extremely necessary in photosynthesis. Water as a solvent -Water is a good liquid to dissolve other substances into. Transport: The blood plasma, tissue fluid and lymph is mostly made up of water. Therefore it is a good place for substances to dissolve, and then move around the body. Removal of wastes: Water is used to carry both ammonia and urea, which are waste products from the body’s metabolism.
Purpose: Try to have a chemical reaction between Alka seltzer and water be controlled so that the lid of the canister pops of in exactly 15 sec. Hypothesis: If a 1/4 of a solid Alka-Seltzer tablet and 15 mL of hot water is added then the lid of the film canister will pop off in exactly 15 seconds. Introduction: v Temperature- causes atoms to move faster v Surface area- more space to react in v ...
Secretions: Water is also used to secrete substances in the body. For example in tears, which mostly consist of water. It seems like there are endless sources of water since we’re surrounded by it every day. Remember that 97% of the water is saltwater from the oceans and 2% is icecaps. Only 1% is fresh water and also from that only a small percentage is accessible. And from what’s accessible, 98% water is used for agriculture and industrial use. There has also been a decrease in annual rainfall.
There’s a limited resources of fresh water. It has also been predicted that with the increase usage of fresh water, there will be a shortage in the next decade. Water is made up of hydrogen and oxygen. Without this this, life on Earth would be nonexistent. It is essential for everything on our planet to grow and prosper. We as humans recognize this, but we disregard it by polluting our rivers, lakes, and oceans. We are slowly but surely harming our planet to the point where organisms are dying at a very high rate.
In addition to innocent organisms dying off, our drinking water has become greatly affected as is our ability to use water for recreational purposes. There are three categories of water resource problems: too much water (salt water & ice caps), too little water (fresh water), and poor-quality water (polluted water).
In order to prevent water pollution, we must understand the problems and become part of the solution. Because…. EVERYONE NEEDS WATER! Thank you
