The tar contains carcinogenic compounds that increase the risk of lung cancer. The small particles in cigarette smoke‚ including carcinogens‚ irritants‚ and

How a faster pulse rate after exercise affects the amount of carbon dioxide in breath and how males and females pulse rates change or don’t after exercise Introduction There is a chemical reaction that takes place in this lab‚ O2 + C6H12O6 –> H2O + CO2 + ATP. This represents cellular respiration‚ the reaction. The reactants are Oxygen and Glucose. The products are water‚ carbon dioxide‚ and ATP. This reaction is split into 3 stages‚ the Glycolysis stage‚ the Krebs cycle‚ and the Electron Transport

Purpose: To investigate the relationship between the speed of sound in air through the pulse-echo experiment and the measured air temperature. Hypothesis: I believe the measured air temperature will affect the speed of sound because sound waves are longitudinal waves composed of the alternating compressions and rarefactions in air. If the air temperature is below 0°C‚ then the speed of sound would be lower than 331.6 m/s and if the air temperature is above 0°C‚ then the speed of sound would be higher

health Every day‚ one is confronted with smoking and its consequences. On the outside of cigarette packets you can read warnings about the risks of smoking. Constantly there are more and more bans against smoking in cafes‚ school etc. It is especially important to inform the younger generation about the danger and the addiction to smoking. Prohibitions and warnings are the best way in order to reduce the number of smokers. The more information about smoking and its harmful effects‚ the more chances

techniques including hip replacement surgery‚ kidney transplants‚ heart transplants and blood transfusions were all perfected in animals. Thanks to animal research‚ primarily in mice‚ cancer survival rates have continued to rise. Herceptin – a humanized mouse protein – has helped to increase the survival rate of those with breast cancer; it could not have been attained without animal research in mice. Animal research is responsible for the development of asthma inhalers; asthma still kills around 2‚000

I decided to do an experiment on cigarettes after I made eighteen‚ which is the legal age to smoke cigarettes. I told one of my teachers about the experiment and she offered bonus points if I turned

The resulting smoke is then inhaled and the active substances absorbed through the alveoli in the lungs.[9] Combustion was traditionally enhanced by addition of potassium or other nitrates.
