Why Are Viruses Alive
What are viruses? An infective agent that typically consists of a DNA acid molecule in a protein coat, is too small to be seen by a microscope, and is able to multiply only within the living cells of a host; viruses are smaller than any infectious bacterial particles. Viruses rely on the host cells they infect to reproduce. While outside of host cells, viruses are protein coats or capsids, sometimes inside a layer of film.
1. A viruses is a non-living infection agent and can be found anywhere. it has no cell organelles. They are eliminated by the immune system. Viruses are the smallest in size of all the microbes.
They weren’t cancerous cells, since they didn’t spread. After Special Circumstances had attacked the Smoke to find Tally Youngblood, Shay, one of Tally’s friends and a runaway, was turned pretty. “I woke up and the whole city was on fire.” said Youngblood, “I tried to escape, I was almost there when one of the specials caughts me. They took me to a rabbit pen, where I saw Shay and the rest of my friends, and she was an ugly.
Dr. George Gey, a doctor and cancer researcher at Johns Hopkins, was presented with cancerous cells that not only survived outside its host but also managed to continue to grow. These cells almost doubled in numbers after being outside of the body for a little under 24 hours. Not only
In the US, cancer is the second major cause of death. Cancer is the uncontrolled division of somatic cells caused by defective cancer cells. Usually, when cells divide, they begin to form a layer. Normal cells will experience contact inhibition, where cells can cease to replicate once there is no more space for it to inhabit. However, cancer cells cannot control their division.
Katherine’s Story By: Kendal Engel Katherine is a sweet, brave girl who loves playing soccer and being outside. At soccer practice she started to feel very ill with a headache and a stomach ache. Her mother took her back home and she started to vomit uncontrollably. “Honey it’s all fine you probably just have the stomach virus that is going around,” declared mom. “Are you sure mom?”
Viruses are obligate intracellular parasites which means they can only reproduce inside a living cell, this means they need a cell to multiply. They do not grow or develop. They maintain the same size. Viruses do not respond to the environment. They do not have energy metabolism, therefore, they do not obtain and use energy.
And this is happening when we have the best of treatments available not just for diagnosing the disease in its infancy but also for making the life as normal as can be with an extended survival and a very good quality of life. I want to ask that when we don’t call a patient a hypertension survivor, a cardiac survivor or a diabetes survivor, then why this discrimination with a cancer patient? It is also like any other chronic disease. Will you help me change this mind-set of the society please?
Viruses do not have the characteristics of a living thing. They have no energy metabolism and they do not reproduce independently. As a result, scientists considered viruses as a non-living thing. Viruses are not living things and they can’t to anything. On the other hand, after they enter a living cell, everything changes and they become living things.
The word Cancer originally comes from a Greek word that means, “a growth, lump, or protuberance” (Sontag 10). Tuberculosis comes from a Latin word that means, “a morbid swelling, protuberance, projection or growth,” (Sontag 10). Both diseases were regarded as diseases that consumed the body however, tuberculosis is a disease that affected the lungs, while cancer can affect any part of the body. Although both have had similar metaphors used, tuberculosis and cancer are almost complete opposites. Tuberculosis has visible symptoms, such as coughing and fevers, while cancer symptoms are typically undetectable until it is in the later stages.
In order to be considered alive, an organism must have the 7 characteristics of life. These characteristics include having structure and organization, response to stimuli, growth and development, removal of waste, obtain and use of materials and energy, the ability to reproduce, and the ability to evolve. Viruses are not living because they do not meet all of these requirements. Cells are the simplest and most basic unit of life. All living things must contain some organized formation of cells.
On a dark early school morning I wake up to feel a bump on my neck. I think to myself “Is this cancer?” I have this minor issue that I always self diagnose myself. One little faintly bump on my neck and I will be researching what it could possibly be for hours on end.
Many people believe if the drug companies find a cure, the patient base goes away. It is much more profitable to keep a steady stream of cancer patients alive, but sick, so that they will keep going back for more drugs. Is this not the same formula for many other modern chronic diseases, such as diabetes? Do not ever believe that if you get cancer, it is merely the draw of bad luck or it is inevitable. The most common cause of cancer, in 90-95% of all cases, is acquired mutations, which are directly caused by dietary and lifestyle factors.
Cancer is an abnormal production of cells that divide uncontrollably within the body (Black & Hogan 2006). What is more vaguely understood are the mechanisms the underlie this, the different effects on each patient, and how to stop it. Some common types of cancer are breast cancer, prostate cancer, skin cancer, leukemia, and brain cancer. Each of these various diagnoses cause different biological and psychological stresses on the patient. Because old cells do not die and instead grow out of control, often, a mass will form, otherwise known as a tumor.
It might not cure cancer but maybe in the near future it might surprise
