Answer
Water is really important for existence of life in this universe and without water life is not possible.
Work Step by Step
Water is found everywhere on earth-snow-covered mountains, hydrothermal vents, arid desert. if there is the existence of water anywhere in the universe then we can expect the existence of life there there is many properties of water that make the existence of life on earth's planet. All life on the earth planet uses a membrane that separates the organism from its environment.to stay alive, the organism takes in important materials for making energy while removing out the toxic substances such as the waste product for whole this process water is essential because water is liquid in nature at earth like temperature .as water can flow so it can provide an efficient way to transfer substances from a cell to the cell's environment. water can transfer things in and out of the cell. water is the most precious resource and abundant compound on the earth's surface, covering more than 70 percent of the planet. In nature, water exists in three states such as liquid, solid, and gas. it is in dynamic equilibrium between the liquid and gas states at standard temperature and pressure. many substances dissolve in water and it is commonly referred to as the universal solvent and this property play an important to make water the most important factor in the existence of life water is made up of 2 hydrogen atoms bonded to an oxygen atom and the way they are bonded together makes the water as the wonderful universal solvent water with it's amazing dissolving properties, is the perfect medium for transmitting substances such as the phosphate or calcium ions into and out of a cell. as water can exist in all 3 stages under a wide range of pressure creates many opportunities for life to flourish .water also has an important structural role in biology water fills cells to help maintain shape and structure water allows everything inside cells to have in the right shape at the molecular level. as the shape is critical for biochemical processes, this is also one of water's most important roles to make it essential for life existence .it also contributes to the formation of membranes surrounding cells .every cell on earth is surrounded by a membrane, most of which are formed by 2 layers of molecules called phospholipids. the phospholipids, like water, have 2 distinctive components -a polar head and nonpolar tail. due to this the polar head interacts with water, while nonpolar tails try to avoid water and interact with each other insted,due whole this interaction phospholipid form bilayer with the head facing outwards the surronding water and tails facing inwards excluding water.this bilayer surrounds the cell and selectively allows substances to enter or exit cell. water also impact some fundamental components of every cell -: DNA and protein .proteins are produced as a long chains of building blocks called amino acid and need to fold into specific shape to function correctly water drives the folding of amino acid chains as different types of amino acid seek and avoid interacting with water. these proteins play important role in the contraction of muscles ,communication,digestion oof nutrients ,excretion process so to continue all these processes strucre of protein should be maintain and to maintain the structure water is really needed Therefore from from above all discussion it is clear that water is really important for existence of life in this universe and without water life is not possible.
