VIRUSES

20070207_virus.jpg <<<<This image shows a bacteriophage injecting the DNA into a cell. An infected cell makes more genetic material and viral protein instead of the usual products. Some viruses stay in host cells for long periods of time, causing no obvious change to the host cell. {This is the lysogenic phase} Until it is stimulated-then it enters a new phase. That's when new viruses form, self assemble, and burst out of the host cell, killing it and and moving on to infect other cells. This is called the lytic phase. Viruses cause alot of different diseases in eukaryotes, in human they can cause
  • smallpox
  • chickenpox
  • influenza
  • shingles
  • herpes
  • polio
  • the common cold
  • rabies
  • ebola
  • hanta fever
  • AIDS

Even some kinds of cancer {not all, but some} have been traced back to viruses.



Bacteria

leptospira.jpg<<<<<<<<This is an image of Leptospira, which causes very serious disease in livestock. Bacteria cause disease for animals and humans. One special type of bacteria called the actinomycetes, it produces antibiotics such as nocardicin and streptomycin. That is one purpose of it, the other function is living symbiotically in the guts of animals and any other places in their bodies. They also live on the roots of certain plants, converting nitrogen into a usable form.

Archea

Archea was discovered and named in the 70s. Archea lives in some of the most extreme environments in the world, from hto springs, to mud in marshes, to the bottom of the ocean. They are also found in the digestive tract of cows, marine life, and termites, where they successfully produce methane. Archaeans may be the only organisms that can live in extreme habitats such as thermal vents or hypersaline water. They are remarkably diverse sea and land organisms. Archea, typified by the methane-producing microbes discovered clustered around hot deepsea vents, where temperatures may exceed 400°C. It is not their rugged constitutions that place these miniscule forms of life in a new category; it is their genomes. They are radically different from those found in prokaryotes and eukaryotes. The genome of one species of Archea collected from a hot vent 3 kilometers deep in the Pacific has been sequenced.

DOLPHIN.jpeg <<<<<<< LIVING ORGANISM
I love dolphins because they are cute and entertaining!! I've raised money for them because they are important to me. People kill them everyday =( I am going to swim with a dolphin this summer in Jamaica [yay!] They are my favorite animal and have been for 7 years. They are fun to watch and learn about.

Important Facts:

  • the dolphin shown above is a bottle nosed dolphin

  • the most common type of dolphin in the US is the bottle nosed dolphin, it is also the most familiar

  • there are 32 different species of dolphins in the world

  • dolphins love to interact with humans and are used in shows and other entertainment around the world

  • dolphins are one of the most intelligent mammals in the world
