They coat themselves in mucus to allow the passage of dissolved oxygen into their bloodstream. The earth transports oxygen and carbon dioxide through the earthworm’s skin by diffusion. For diffusion to occur‚ the earthworm’s skin must be kept moist or

and another Cyril West were appointed to study ways to improve fruit storage. Applying information obtained while studying seed germination‚ Kidd and West demonstrated that fruit ripening could be retarded by increasing carbon dioxide and lowering oxygen in the storage atmosphere. And‚ from that day onwards and still ongoing‚ constant efforts are being made to control the atmosphere surrounding commodities and fruit‚ to help improve business logistics and better serve the customer.

interferes with cellular respiration. If inhaled‚ Hydrogen Sulphide combines with haemoglobin in the bodies of human beings and other mammals. haemoglobin is the substance in blood which carries oxygen to tissues. In combining with the haemoglobin‚ hydrogen sulphide prevents the transportation of oxygen. Without oxygen‚ people cannot live. Although hydrogen sulphide is very foul smelling‚ it can quickly paralyse the sense of smell‚ overcome the victim‚ and cause death.It also causes irritation of mucous

The initial research of sports science was to ensure energy levels and oxygen consumption to decrease fatigue and risks of injury (Hendricks). Latest in sports technology includes the RespiBelt. It acts as a free-weight made of elastic bands that strengthens breathing muscles. Breathing comes easy at rest‚ but as physical activity

Interestingly‚ it is also this ultraviolet radiation that forms the ozone in the first place. Ozone is a special form of oxygen‚ made up of three oxygen atoms rather than the usual two oxygen atoms. It usually forms when some type of radiation or electrical discharge separates the two atoms in an oxygen molecule (O2)‚ which can then individually recombine with other oxygen molecules to form ozone (O3). The ozone layer became more widely appreciated by the public when it was realized that certain

experiment was conducted to see if the brain would perform better in mathematical tasks‚ if there was an increase in blood flow through exercise. The increase in blood flow should help the brain to perform better as it receives more oxygen. This is because all cells require oxygen for cellular respiration. To test this‚ three females‚ aged 16-17‚ were asked to answer four mathematical questions for four trials. As each trial progressed‚ subjects had to run on the spot for an extra 30s. It was clear from

formed from reaction of ammonia and oxygen. Nitric acid is a colourless acid when it’s pure‚ or can be found yellow or red. This acid can be very corrosive to eyes and skin and can cause severe burns to human skin and tissues. It is miscible to water‚ and has a very pungent smell. Nitric acid is very reactive and can is able to melt many metals‚ and non metals. As a solution‚ nitric acid is known as a good conductor of electricity. When combining ammonia and oxygen‚ water and nitrogen‚ it is known
