Outcome 1 Understand the cause of infection 1.Identify the difference between bacteria, viruses, fungi and parasites. Bacteria Bacteria is a single celled organism, bacteria have evolved to thrive in almost any environment and can be found in almost any substance/surface and also in the human body, only 1% of bacteria is actually harmful. It's bad or infectious bacteria that cause illness as they rapidly reproduce and produce a toxin that kills or mutates cells, bacteria is also self sufficient. Viruses A virus is a small capsule that contains DNA or RNA, viruses, unlike bacteria are not self sufficient and need a host in order to reproduce I.E a human body. When a virus enters the body, it enters some certain cells and takes over making the now host cell make the parts the virus needs to reproduce, the cells are eventually destroyed through this process.
In fact only 1% of bacteria are harmful. Viruses can only grow inside the cells of living organisms. They are not living in their own and in that way are different to bacteria, parasites and fungi. All living organisms can contract viruses: humans, plants, fish and animals. Viruses are spread from host to host.
Spiny Anteater The unusual animals called echidnas are also known as spiny anteaters even though some eat mostly earthworms. The echidnas and the platypus are the only living mammals that lay eggs. Until recently scientists believed that there were only two species, or kinds, of echidnas—the long-nosed echidna and the short-nosed echidna. In 1999 a new species of long-nosed echidna was identified, but little is known about it. Where echidnas live Echidnas usually live in forests and meadows, often at high elevations.
Identify the differences between bacteria, viruses, fungi and parasites Answer: Bacteria Bacteria are single-cell microorganisms which generally exist in large numbers and are microscopic in size. Bacteria can be either beneficial (bacteria in the intestinal tract aid digestion and are part of the normal body flora) or can be the cause of disease (for example pneumonia, food poisoning or bacterial meningitis). Viruses A virus is an infectious agent which can only live and replicate inside organism cells. The main difference between viruses and bacteria is that they are unable to reproduce in food – they need a living host cell to replicate. They replicate by infecting and taking over the functions of the host cell.
1) 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). They are ten to 100 times larger than viruses.
Most of the E. coli are normal inhabitants of the small intestine and colon and do not cause disease in the intestines (non-pathogenic). Nevertheless, these non-pathogenic E. coli can cause disease if they spread outside of the intestines, for example, into the urinary tract (where they cause bladder
By examining the bones of food waste found in and around the site, it is known that wildlife was an important part of the diet in Jamestown. Animals are believed to have composed approximately half of the food included in their diets. The people of Jamestown rarely ate communally and were often expected to fend for themselves, with the gentlemen eating at separate tables and of their own private stocks of food. The commoners often used large cast-iron pots to cook one-pot meals such as stew, soup or “potage” over fires. This was convenient as they required little attention and were easy.
The wall of a jellyfish body is very fragile. Their bodies are much different then that of most animals. They have no brain, no respiratory system, and no circulatory system. The average length of a jellyfish tentacle is one to ten meters long. The tentacles of a jellyfish in some cases can grow to a massive length of 100 feet!
Iowa grows the most corn of all 12 states. They grow the majority of corn produced in the States. 8) Corn is used for a variety of non-food sources form adhesives to explosives. It is also used in plastic and has a total of about 400 non-food uses. 9) Corn as we know it was not found in nature, but was developed over
The Arthropod I chose to research is Scorpions. Scorpions are a member of the Arachnida class. They are closely related to spiders, mites, and ticks which are multicellular, eukaryotes, have an exoskeleton made of chitin, and have jointed appendages. These insects have been around for hundreds of years. There are almost 2,000 scorpion species, but only 30 or 40 have strong enough poison to actually be able to kill a person.
