Organism Physiology Paper Dolphins are one of the most familiar and unique marine mammals known to people and occupy all the major oceans and seas of the world. Some species are even known to live in larger river systems. Dolphins belong in the kingdom anamalia; phylum‚ corata; class mammalia; order‚ cetacean; sub-order‚ odonteceti; family‚ delphinidae; genus‚ delphinus; and species‚ delphis. Dolphins are believed to have a long evolutionary past dating back several‚ tens of millions of years

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

Introduction Genetically Modified Organisms (GMO)‚ are organisms whose genetic material has been artificially manipulated in a laboratory through the means of Genetic Engineering. It is when a gene from one organism is taken and inserted into another in order to improve and produce a desired trait for that certain organism. Sometimes it is known as "transgenic" for transfer of genes. Mostly‚ GMOs are done with agricultural crops and animals that are consumed for food. Food‚ most needed by humans

Enzymes are biological catalysts‚ large protein proteins that have a very specific three-dimensional shape which makes them highly specific and only work on one or a few similar chemical reactions. Enzymes themselves are not consumed in the reaction‚ but they help attract substrates into correct position to undergo chemical reaction. Enzymes greatly speed up the rate of biological reactions by lowering the energy of activation. To get a sense of the speed and efficiency of enzymes‚ substrates can

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

Kranworth Chair Corporation produced a range of high-quality‚ trendy yet portable folding chairs. The company was protected by patents and had been enjoying sales growth. However‚ the company started experiencing changes in the environment‚ such as expiration of patents‚ having more competitors and even worldwide recession in the 2000s‚ resulting to a drop in profits. Kevin Wentworth‚ CEO and co-founder of KCC‚ decided to change their strategy from increasing quantity of sales to improving quality

The FDA lists consultations on GMO foods and what was genetically modified in the food to warrant the safety consultation on its website. GMOs‚ or “genetically modified organisms‚” are plants or animals that have been genetically engineered with DNA from bacteria‚ viruses or other plants and animals. These experimental combinations of genes from different species cannot occur in nature or in traditional crossbreeding.

with changes that occur in environmental temperature‚ wavelength of light‚ and light intensity. Using a photosynthetic organism of your choice‚ choose only ONE of the three variables (temperature‚ wavelength of light‚ or light intensity) and for this variable. • Design a scientific experiment to determine the effect of the variable on the rate of photosynthesis for the organism • Explain how you would measure the rate of photosynthesis in your experiment • Describe the results you would

Chemistry 12 Formal Report Measuring Reaction Rate using Volume of Gas Produced By John Doe 23th October 2012 Introduction An essential element of chemistry is finding reaction rates. This is because chemists need to know how long a reaction should take. In addition to needing to know the rate of a reaction at any point in time to monitor how the reaction is proceeding. Many factors effect reaction rates‚ two shown above include temperature and concentration. Concentration affects the

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‚ which means the soil in which the vegetation grows has been implicated with acidic chemicals from the rain. The acid in the rain does not kill the trees directly. Instead‚ it slowly damages and injures the tree’s leaves and parts by limiting them from their nutrients
