Viruses: A virus needs a host cell to replicate. Viruses are immune to antibiotics and are spread in the air or by direct contact, which mean they probably are more commonly caught from each other. They can lead to serious or sometimes deadly diseases such as aids. Virus can also cause chickenpox, common cold and influenza. Parasites: A parasite is an organism that lives in another organism.
In today’s society “We have a modern arsenal of chemical weapons to fight off these invaders and we use them lavishly” (D.Suzuki). All this fear and disgust is caused by the way we, as children, have been conditioned by society. David believes this is slowly destroying our planet, and is the cause of hundreds of
So the immune system responds by making antibodies that attack the body’s normal cells. If you have lupus something is wrong with your immune system and it attacks healthy cells and tissues. Lupus has tripled since 1970. Lupus can range from mid-to life threatening and should always be treated by a doctor. With good medical care, most people with lupus can lead a full life.
Bacterial infections are normally treated with a course of antibiotics. Viruses are made up of genes and proteins that spread throughout the body by invading the body’s own cells so they can reproduce and multiply in the body. They use the body’s cells as a host because they are unable to multiply on their own. They are normally spread directly from human to human. Viruses can be very tough and there are not many effective medicines available for viral diseases.
To be pathogenic, a parasite must invade the host, resist internal defenses long enough to begin growing, then harm the host in some way. Pathogenic prokaryotes cause about half of all human diseases. Opportunistic pathogens
Preston also produces an effective atmosphere of fear by displaying that doctors, who are almost always viewed as being heroic, can just as easily, if not so faster than any human being, get the virus. Preston constantly reminds us of how tiny and how dangerous a virus is. The impact of Ebola or Marburg could extinguish the entire planet if it got a grip. “Within 24 hours, a virus could make its way out of Africa on a plane and into such places like London, Paris, or New York and then spread out to the rest of the world.” The tiny HIV virus has already spread damage throughout the human population of the world, and this is a point the author makes numerous times. A very minute amount of contaminated blood is enough to infect a human with the Ebola virus, so those working in the Hot Zone must always be careful for the smallest little tear that might allow it into their space suits.

“Meth causes the blood vessels to constrict; it cuts off the steady flow of blood to all parts of the body. Heavy usage can weaken and destroy these vessels, causing tissues to become prone to damage and inhibiting the body's ability to repair itself.” (Visible Signs, paragraph 1) A really big appearance change that happens when using this drug is the aging process. The body loses the elasticity and luster that causes you to look young in such a short amount of time. Another really bad thing that can happen to your body with all the Methamphetamine use is the hygiene of the mouth. “The drug causes the salivary glands to dry out, which allows the mouth's acids to eat away at the tooth enamel, causing cavities.” (Meth Mouth, second

This a sport that is appeals to a huge audience and is found disgusting to parents with young children and a variety of politicians.

Drowning in Plastic It’s hard to imagine life without plastic. It’s everywhere: covering our food, holding our purchases, protecting our loved ones, saving patients in hospitals and floating along our waterways and oceans. The thought of living in a world surrounded by toxic chemicals and pollution is a thought which many would rather not think about. Plastics have revolutionised the world in which we live, but with dire consequences. The production of these toxic-filled substances continues to lead the human race on a path of natural destruction; with thousands of animal sea-life dying annually from plastic consumption.
