Experiment to test level of carbon dioxide in water

HAEMOGLOBIN CONCENTRATION Introduction Red blood cells contain the protein molecule haemoglobin (Hb); it is made up of four polypeptide chains and contains iron. Its function is to carry oxygen from the lungs to the bodies tissue and to carry carbon dioxide from tissue back to the lungs. Anaemia can be caused when there is a lack of iron in the body which leads to a reduction in the number of red blood cells. Iron is used to carry oxygen in the blood so If you have fewer red blood cells than is…

earthworm’s skin is preserved by a thin cuticle and remained moist by a slimy mucus. This lets it absorb the oxygen it needs and eliminate carbon dioxide. If a worm is dried up by the sun, it will die since the exchange of gases cannot occur . However to…

animals each year are killed in the U.S laboratories for drug, food, chemical, and cosmetic testing (People for Ethical Treatment of Animals)? These animals are used to test safety of products for human use, toxicity levels of medication, and many other types of scientific and commercial testing. “95% of animals used in experiments are not protected by the federal Animal Welfare Act (AWA)” (Procon). AWA is the only law that regulates treatment of animals in research testing. Animal testing is…

In a separate beaker of 200 ml of fish water, a 50mg caffeine tablet was dissolved. To accurately test the effect of caffeine on oxygen consumption, the same two fish were used for both the control and experimental trials (Trial 1). After receiving our data from LoggerLite and transferring it on an Excel sheet, 100mL of fish water was removed from the oxygen chamber and 100 mL of caffeine-treated fish water was added to the chamber. Once the plunger was placed back on the…

EXPERIMENT SETUP A single-cylinder, 4-Stroke, water-cooled diesel engine of 5 hp rated power is considered for the experimentation. The engine is coupled to a rope brake dynamometer through a load cell. It is included with a data acquisition system to store the data for the off-line…

Southern Maine to feed into Nequasset, the lake that supplies our water. Any pollutants that get into these tributaries will eventually make their way into Nequasset, and the many ecosystems inside them play a small role in the overall…

physical motion is produced (Greeshma, 2016). ADP can be converted back to ATP so that it can be used again, this is known as the ATP-ADP cycle (Figure 1). The mitochondria of the cell produces ATP under aerobic conditions where there is a sufficient level of oxygen available. This process utilises glucose,…

Many devices, medications, makeups, and other things that are used by humans on a daily bases are tested on animals. These things are all created in labs and go through so many trial and error experiments that the scientists and manufacturers do not want to have to use humans to see if they are safe or not. Instead, they use animals to do their research. But who is to say that testing on animals is the best way to go. There are many other means of testing medications and other products rather…

Photosynthesis is a biochemical process from light using energy from sunlight and carbon dioxide from the atmosphere as reactants to produce oxygen and organic compounds like carbohydrates (Campbell et al. 2015). Photosynthesis takes place in photoautotrophs including all plants, algae, some kinds of bacteria, and protists. The simplified equation is: CO2 + H2O → carbohydrates + O2. (Sadava et al. 2014). It is broken down into two parts: light reaction and light-independent reaction (Campbell…
