What if you didn’t have enough water to do your daily activities. California is in a humongous drought. The egocentric farmers are using water for the food‚ but the people need water for themselves. Like taking showers‚ and water for washing their clothes. There isn’t enough water for the people to use the aquifer for their needs. The citizens go months or weeks without showering. The people even have to use bird baths to shower. California should control the aquifer use. Moreover‚ since the farmers

However‚ according to the data released by Water Environment Partnership in Asia (WEPA) in 2005‚ 42.89% of the waters in the Philippines are contaminated. These contaminated waters have not only been continuously harming people‚ but also the aquatic

BIOCHEMICAL IMPORTANCE OF WATER Of all the simple chemicals that are found in abundance on Earth‚ only water is liquid under normal pressure and temperature. When life first appeared on planet Earth‚ water has played an important role in creating the first organic compounds. The organic compounds later‚ formed the first prokaryotic organisms. Life began‚ as the modern theories support‚ in water and developed for three billion years in it before spreading on land. It is no coincidence that the

in a fluid‚ such as water. Since virtually every living organism requires oxygen to survive‚ it is a necessary component of water systems such as streams‚ lakes and rivers in order to support aquatic life. The dissolved oxygen is measure in units of ppm—or parts per million. Examine the data in Table 2 showing the amount of dissolved oxygen present and the number of fish observed in the body of water the sample was taken from; finally‚ answer the questions below. Table 2: Water quality vs. fish population

Importance of Water for Living Organisms Water is made up of two elements‚ 2 positively charged hydrogen molecules and one negatively charged oxygen molecule. Water molecules have uneven charge distribution as one end of the molecule is slightly positive and the other slightly negative‚ this is called polar. Ionic substances such as sodium chloride dissolve easily in water because the positively and negatively charged ions are separated due to the dipole nature of water. As water is dipolar‚

____________ Properties of Water Lab Introduction: Water is a simple molecule‚ yet itʼs most vital to all living things. It has the highest specific heat of everyday substances. Unique properties of water enable it to carry out functions that no other substances can. In a neutral aqueous solution‚ five molecules of water are bonded together by weak hydrogen bonds. Furthermore‚ due to the electronegativity of oxygen‚ water is a polar molecule. Due to its polarity‚ water is classified as the universal
