... decomposers. A dead organism holds valuable nutrients, all of which remains intact without the activity of putrefying bacteria (decomposers). Decomposers are saprophytic organisms whish exploit the energy source and break down the organic compound of which the dead organism constitutes. ...

... selected for use in that application. The two yeast here compared, have two such different applications. The first yeast from the Saccharomyces cerevisiae variety is of the Hansen strain and is used in the baking industry, whereas the second also of ...

... process of photosynthesis. In order for these organisms to achieve Autotrophic nutrition, they must gather together many raw materials from its environment for photosynthesis to occur. Plants require a source of carbon dioxide and water, chlorophyll to collect absorb the ...

... The outer surface of the shell is greyish white, sometimes with a yellow tint, and has crude radiating ridges and well-marked growth lines. The inner surface is smooth and greenish-grey in colour. The sole of the foot is yellowish, dull ...

... associated with searching for food.ÝÝ The optimal foraging theory assumes that animals feed in a way that maximizes their net rate of energy intake per unit time (Pyke et al. 1977).Ý An animal may either maximize its daily energy intake ...

... 10 to 18 year old boy would differ from that of a 10 to 18 year old girl with the same body mass and PAL as the boy, the girl would need less energy than the boy would. That of an ...

... by highly specific enzymes. When only one phosphoryl group is added to the ribose sugar and base adenine, the nucleotide adenosine monophosphate (AMP) is formed; adding a second phosphoyrl group makes adenosine diphosphate (ADP); and adding a third makes ATP. ...

... organism to do work endergonic reactions must be linked with exergonic reactions. The energy that the body requires is provided by respiration where the aerobic oxidation of a glucose molecule provides 2870 kJ of energy. Respiration is not just one ...

... has no smell. It only occurs naturally in small amounts. Caffeine has tiny crystals on it that look like needles. Caffeine was produced from plants in the pure form in 1820. Caffeine is used in prescriptions for some disorders to ...

... There are different kinds of energies like kinetic, thermal, heat, electrical, solar, potential and many more. These energies are transferred and obtained from different sources, which are namely classified as renewable and non renewable sources of energy. It is recognized that ...

... across the globe caused the year-round temperatures to shoot up unstoppably. If the human race does not change the current lifestyle, this sad tale could one day be a reality. To prevent this from happening alternative energy sources should be ...

... can be only refined using huge amounts of electricity and electricity did not become readily available until this century. Thus, it is known as the metal of the 20th century. There are three process involved in the manufacture of Aluminium: ...

... detrivores and fungus-eaters. Since energy is lost in each step, populations are necessarily smaller at each higher level of the pyramid. ...

... potential energy. the first step of respiration is glycolysis.the process converts glucose in to puruvic acid which needs 2 molecules of atp to iniate the reaction and consequently produces 4 molecules of atp. Thus produces a net gain of 2 ...

... same throughout the experiment whilst taking results as if they are not the results may be inaccurate and inconsistent in respect to what they should be. I think that as wind speed increases the rate of transpiration will increase, this ...

... healthy, bad disease causing bacteria can take over the intestinal tract and cause gastro-intestinal disease and cancers. Waters are the main solvent for food to dissolve in and to be carried around the body. Most of the human body is ...

... no oxygen present. When Yeast cells respire anaerobically they produce energy (ATP), alcohol and carbon dioxide.(2) C6H12O6 2C2H5OH + 2CO2 Microbes such as yeast have optimal temperatures within which they work most efficiently, the reason for this is that the enzymes within ...

... different from biotic factors in that they don't involve other organisms. This means that anything, which affects an organism in its ecosystem that is not living, is classed as an abiotic factor. Popular examples of abiotic factors include the climate ...

... the amount of work that the body can as it falls towards the Earth under the pull of gravity. Potential energy, like kinetic, can be used to do useful work. In a hydroelectric generating static for instance, water falls from ...
