Why is water important for living organisms? Water is very important in all living organisms‚ it is vital for many different things. Around 70% of our body weight is due to water. The quantity is high in organs such as lungs and brain and fluids such as blood‚ lymph‚ saliva and secretions by the organs of the digestive system. First of all water is vital in the regulation of body temperature to depending on the temperature mammals will alter the amount they sweat. If they are to warm the amount

The Process of Osmosis and its Importance to Living Organisms. Osmosis is the diffusion of water through a semipermeable membrane that does not allow dissolved solids (solutes) to pass. Osmosis refers only to diffusion of water and the direction of movement is from the area of higher concentration to the area of lower concentration. This migration of water from a region of higher concentration to a region of lower concentration is spontaneous and although water molecules move in both directions

Adenosine Triphosphate‚ also known as ATP‚ is the molecule responsible for the energy that we‚ and all other organisms‚ need to survive. It is produced primarily in the processes of aerobic and anaerobic respiration by oxidative and substrate phosphorylation. 4 molecules of ATP are produced from 4 ADP and 4 inorganic phosphates in glycolysis in the cytoplasm of every cell‚ by the oxidation of a triose phosphate into two molecules of pyruvate. In anaerobic respiration these are the only 4 ATP

evaporate sweat that forms on the surface of the skin from the sweat glands and this results in a reduction in body temperature as energy is used up. Also‚ cells are made up of 80% water and the specific heat capacity of water means that bulky organisms have fairly stable temperatures. Support is vital to both plants and animals and often water plays a significant part in this. In plants water is responsible for making the cells of the plant turgid by osmosis and therefore providing support‚ particularly

Process of Diffusion and its importance in living organisms Diffusion is the movement of molecules or ions down a concentration gradient i.e. from an area of high concentration to an area of low concentration. For a diffusion system to be efficient‚ it should have a large surface area so that high amount of substances can be exchanged at a time. It should also have a thin membrane and a continuous supply of substances‚ as a thin membrane means that the diffusion pathway would be short‚ and the continuous

Acid rain does not only degrade the environment‚ it causes negative issues on political‚ social and economic factors. Forests are affected greatly by the impacts of acid rain. Through years of research‚ scientists‚ foresters and environmentalists have discovered how acid rain has slowed down the growth of some forests and plants. The effects acid rain has on trees is change of colour and in some extreme cases the individual trees die off completely. Soil degradation is also an effect of acid rain

Abstract Acid Rain has a lot of effects on living organisms and on the environment. This experiment has two purposes. One is to determine the acidity of rainwater in certain areas in the Philippines. Another purpose is to determine which type of area-urban or rural- is more subjected to acid rain. The experiment was done by first collecting rainwater from selected rural and urban areas. After the collection was done‚ the rainwater samples were tested using a pH meter. The results of the pH test

Lab 4: Fungi Non-filamentous forms — Single-celled Yeasts Do an Internet search for a microscopic image of baker’s yeast‚ Saccharomyces cerevisiae (Ascomycota). Answer the following questions: 1. Do the yeast cells have a definite shape or is there considerable variation? Yeast cells seem to vary in shape‚ some look to be more oval and round‚ although. some slides did show pear and cylinder shapes. 2. Can you detect any subcellular structure? I cannot detect a clearly visible
