(2 points) Discuss the arguments for and against the classification of viruses as living organisms. For: viruses are classified as living organisms due to their possession of DNA or RNA in their systems. DNA and RNA are essential components of any living organism.…
A “virus” is defined as: “an infective agent that typically consists of a nucleic acid molecule in a protein coat, is too small to be seen by a light microscope, and is able to multiply only within the living cells of a host” (Document B). Originating from Uganda, the Zika virus was first discovered in 1947 in an infected money in the Zika forest, where its name originates. The Zika virus is a typical one-stranded RNA virus with nucleotide sequences relating it to other African and Asian virus strains. It is capable of infecting other species such as monkeys, elephants, lions, zebras, and rodents. Primates, like humans and monkeys, are known to be the primary hosts and reservoirs.…
The Variola Virus The Variola virus, which exists in two strains, Variola Minor and Variola Major, has been the cause of one of humanity’s most devastating diseases -- smallpox. This disease is around 200-400 nanometers small and is oval or brick-shaped. The Variola virus, and including all other viruses, are not considered alive. They reproduce by coming in contact with a host cell (for the Variola strains, human animal cells) and injecting their DNA into the host to take its functions over.…
The definition of a virus from the Oxford Dictionary is, an infective agent that typically consists of a nucleic acid molecule in a protein coat, is too small to be seen by light microscopy, and is able to multiply only within the living cells of a host: To me that means that they are these tiny molecules that are not cells, but able to multiply, but only inside of the cells of the person the virus has gone into. Viruses are not living things. They do have many things inside them that a living thing may have like proteins, nucleic acids, carbohydrates and Lipids. the problem is that they can't function…
Viruses “rely on their hosts to carry them around and introduce them to new hosts” (Survival of the Sickest, paperback, p. 119). The cold virus knows that its host has to be relatively healthy so its ride can be mobile (Survival of the Sickest, paperback, p.119). The virus has evolved with humans to allow it to reproduce faster and survive more efficiently. If you take the host out of the picture, the cold virus could never survive or reproduce. The rabies virus is another manipulative virus.…
In this essay of Roe V Wade, I believe that the court made the correct judgment. There are many topics that are heatedly debated in today’s society. Abortion, however, is a topic that never seems to get settled. With so many people from different walks of life residing in the United States, there are bound to be several clashing views and opinions on the subject of abortion. The court case of Roe V. Wade has to be the greatest stepping stone in the subject of abortion.…
In World War Z, by Max Brooks, a zombie virus ravages the lands leaving all in its ways in ruins. Human society is on the break of collapse and a solution must be formed before the human race becomes extinct. Natural selection and genetic engineering are both front runners in theories of solution to the problem however natural selection move the human race further with less consequences in the future. The solution of the zombie virus is to allow natural selection to take its course and allow those who are less dependent on society to live and flourish through the chaos. Living through natural selection will require several conditions to be met for a human to survive.…
For a very long period of time, pathogens, or disease-causing organisms and substances, have truly devastated humanity. Numerous prominent personalities of history have been afflicted by such complications. George Washington, in the early years of the American Revolution, was bothered by one of the notorious variola diseases through the course of time: smallpox. He described such conditions caused by these viruses as a potentially greater threat; greater than “the Sword of the Enemy”. This virus not only threatened his life, but it compromised their victory of Washington’s army as well, when they were fighting for independence from Britain (Mount Vernon Ladies’ Association, 2015).…
Abortion is very common. In fact, three out of ten women in the United States will have an abortion by the time that the are 45 years of age. but abortion is nothing new. In fact, abortion first abortion happened in the late ninth century. Since the 1970, nearly one and a half billion unborn children have been lost to abortion worldwide.…
Current Events of the Bubonic Plague-CNN 2015 The CNN article is describing the Bubonic Plague. The Plague continues in our country today and nearly fifteen people die every year because of it. Not many people are suffering from it today, however a fourth of all people that continue to get it today, die.…
The 1918 “Spanish flu” Pandemic was caused by an avian-like influenza virus that gained the ability for efficient and sustained human-to-human transmission and then spread globally, killing 20-50 millions. Fortunately, viruses with pandemic potential are rare occurrences and ongoing surveillance of human and avian viruses is being done globally in preparedness for an influenza pandemic. Vaccines and anti-viral drugs may be available, if needed and time permits. Both kinds of therapies have shown some effectiveness against the 1918 pandemic stain. As a post -doctoral fellow at St Jude Children’s Research Hospital in Memphis, TN in the laboratory of Dr. Yoshiro Kawaoka, I studied host range restriction and receptor specificity of influenza…
Abortion has been allowed every since Roe vs Wade trial in 1973 (McBride). It was decided that the only way for abortion to be legal is if it was deteriorating the mother’s health (McBride) But if one whole is in the house and one mouse comes in, the rest are right behind it. These different morals contradict one another when considering abortion. One main controversy is over at which point does a group of cells become a baby: at heart beat, upon conception, when born?…
Introduction The movie ‘Outbreak’ came out in cinemas in 1995 shortly after the discovery of the Ebola HF virus in the late 1970s. This movie dramatizes the Ebola HF virus and portrays it as the fictional Motaba virus, it shows in a dramatic Hollywood way how the US would react to a deadly disease outbreak. Of course, being a Hollywood movie there are some facts and many fallacies in the finer, more scientific aspects of the disease. The biosecurity facilities used to control the spread of the disease are not accurately portrayed and the evolution of the disease is ridiculous and very inaccurate. Scientific Information Viruses In and Out of the Movie…
Viruses; Who is the Beholder? The greatest threat to humanity can’t be seen by the untrained eye. It could lay dormant for millions of years and evolve into the most terrifying form of itself. These infectious viruses create worldwide terror. The 2011 film Contagion by Steven Soderbergh does an incredible but also frightening job of revealing how a lethal virus would impact the Earth.…
The possibility of being capable of changing the human genome to prevent or treat devastating illnesses and serious inherited diseases has always being in the mind of many people and scientists. However, two important events may contribute to make this idea a reality in the near future. One is the decoding of human genome. This has allow scientists the opportunity to comprehend how the genetic information controls the growth, configuration and function of the human body; and at the same time, to understand how variations within our DNA sequence cause diseases.…
