Water Balance Adipose tissue is one of the most hydrated of all tissues in the human body. False The most abundant cation in intracellular fluid is sodium. False Electrolytes determine most of the chemical and physical reactions of the body. True Solutes‚ regardless of size‚ are able to move freely between compartments because water carries them along the osmotic gradients.False The thirst center in the brain is located in the hypothalamus.True Dehydration can be caused by endocrine disturbances

Have you ever dropped oil on your hands and tried to wash it off? What happens? Does the water slide off? Or what about when a drop of oil falls in a glass of water? Why does it float to the surface‚ and not mix? The answer to this is simple: polarity. What exactly is polarity? A polar bond is when there is a difference in electronegativity‚ which means the tendency of an atom to attract a bonding pair of electrons. When two atoms are bonded together and one attracts more electrons‚ this results

properties of water were tested and proved. These trials and experiments were able to verify the adhesion‚ cohesion‚ polarity‚ temperature stabilization‚ solvency‚ and density changes exhibited by water. During the glass and wax paper lab‚ we observed the adhesive properties of water. When a droplet of water touched the glass‚ it dispersed immediately. The droplet placed on the wax paper remained intact and in droplet form. Also‚ when the glass and wax sheets were flipped‚ the water remained on

is called simmering. Simmering is cooking the chicken with chicken broth or water. This makes the chicken tender and soft‚ ready to be fried. Firstly‚ rinse each chicken breast. If the breasts are frozen‚ allow them to fully defrost before boiling. The chicken breast can also be defrosted in the microwave‚ in the refrigerator‚ or by soaking it in a bowl of cold water. After defrosting the chicken is soaked in salt water it take the slimly taste out of it. Most Africans do this before cooking any

The Biological Importance of Water! The ultimate importance of water is none other than the fact that life cannot exist without it. Water being the major component of our body cells‚ typically making 70-95% of it‚ constructs the body mass with approximately 80% being water. Humans are not the only ones who contain the valued material but other creatures like the jellyfish hold 96% of water as their body mass. The structure of the water molecules enables it to have extreme properties that are

Our Earth is a place where beauty exists‚ a place where 6.6 billion people and 15 million other species live‚ a place filled with 1.4 cubic kilometers of water. Although 70% of the planet’s surface is blanketed with deep oceans water‚ freshwater only form less than 3% of the total water and the rest are saltwater. Besides that‚ only 30% of the

97% of the water on the Earth is salt water and only 3% is fresh water which the majority of human uses require; slightly over two thirds of this is frozen in glaciers and polar ice caps. The remaining unfrozen fresh water is found mainly as groundwater‚ with only a small fraction present above ground or in the air. However‚ water is now being heavily polluted by nobody else but human. So what are the causes and effects of water pollution? The causes of water pollution vary. However‚ we can sum

before it reaches the aquifer. Uses include water for garden‚ water for livestock‚ water for irrigation‚ etc. In many places the water collected is just redirected to a deep pit with percolation. The harvested water can be used for drinking water as well if the storage is a tank that can be accessed and cleaned when needed. advantages • Makes use of a natural resource and reduces flooding‚ storm water runoff‚ erosion‚ and contamination of surface water with pesticides‚ sediment‚ metals‚ and fertilizers

of saving water 1.0 Introduction In our life‚ water plays an important role. It is the source of life. It is a irreplaceable element with human survival and development. Our life can not without water‚ depend on research‚ human can’t without water more than 72 hours‚ fish can’t without water more than 20 minutes‚ plants can’t live without water also‚ on the earth‚ where has water‚ there has life. Life originated from water. 65% of our weight is water‚ there into‚ 75% of brains is water‚83% of blood
