1.1 Identify the differences between bacteria‚ viruses‚ fungi and parasites Bacteria are a single celled organism that multiplies by themselves. The majority of bacteria’s are harmless and beneficial to the human body but some can cause infectious diseases. A bacterium usually affects one part of the body and doesn’t spread across or through the body. Bacterial infections are normally treated with a cause of antibiotics Viruses are made up of genes and proteins that spread throughout the body

ends of the blood capillaries. • Absorption of water by the alimentary canal — stomach‚ small intestine and the colon. Osmoregulation Osmoregulation is keeping the concentration of cell cytoplasm or blood at a suitable concentration. (a) Amoeba‚ living in freshwater‚ uses a contractile vacuole to expel the excess water from its cytoplasm (thus need more respiration/O2/ATP than isotonic (marine) Amoebae). (b) The kidneys maintain the blood (thus‚ whole body) at the correct concentration.

glucose cannot be used by cells until it is stored in ATP. Cells use ATP to power virtually all of their activities—to grow‚ divide‚ replace worn out cell parts‚ and execute many other tasks. Cellular respiration provides the energy required for an amoeba to glide toward food‚ the Venus fly trap to capture its prey‚ or the ballet dancer to execute

main parasites include ectoparasites‚ which are those living on the external of the host (mosquitos‚ ticks) and endoparasites‚ which live internally in the host (worms). Nematodes or roundworms‚ cestodes or tapeworms and trematodes or flukes are the three categories in which endoparasites can be divided. Barbers Pole Worm is a nematode which attaches to and causes lesions to the fourth stomach or abomasum of sheep‚ and obtains nutrients through the blood. Large infestations of the parasite

Hepatitis C Cause The biggest cause of Hepatitis C contraction is when a person comes into contact with the blood of someone who already has Hepatitis C. The most common cause of Hepatitis C via blood is through the sharing of needles and other equipment such as cotton‚ spoons and water that are used to inject illicit drugs.

unit 4222- 265 1 1.1: identify the differences between bacteria‚ viruses‚ fungi and parasites. Bacteria are living things that are neither plants nor animals‚ but belong to a group all by themselves. They are very small--individually not more than one single cell--however there are normally millions of them together‚ for they can multiply really fast.Bacteria are prokaryotes (single cells that do not contain a nucleus). Every species has a great ability to produce offspring and its population
