Discussion 1. Zn0 (s)+ Cu2+S6+O42-(aq) →Cu0(s) + Zn2+S6+O42-(aq) Zn0(s) → Zn2+(aq) + 2e- Cu2+(aq) + 2e- → Cu0(s) Zn0(s) + Cu2+(aq) → Zn2+(aq) + Cu0(s) Oxidant (oxidizing agent) is the element which reduces in experiment.
Viruses are capsules with genetic material inside. They are very tiny, much smaller than bacteria. Viruses cause familiar infectious diseases such as the common cold, flu and warts. They also cause severe illnesses such as HIV/AIDS,
These viruses include the following: herpes, measles, fowl pox, mumps, and equine encephalitis. It was said that Henrietta’s cells helped launch the field of virology. The book also mentions how viruses reproduce by injecting some of their genetic material into a living cell, essentially reprogramming the living cell so it reproduces the virus instead of itself which is a concept we have learned this semester (Skloot, Location
A virus is an infective agent that usually consists of a protein coat with a nucleic acid molecule. Viruses do not reproduce through asexual reproduction. Instead, they attach themselves to the cells in their victim’s body to create more viruses. Over the years, vaccines for certain viruses have been created to help humans combat them. However, for viruses such as Ebola, there have been no drugs approved to cure them.
However, this determination is not always straightforward. Viruses have some, but not all, of the qualities of living organisms, and scientists have long argued whether or not they should be considered as living organisms. In this exercise you will determine whether specimens are non-living, living, or dead. CHARACTERISTICS OF LIFE - STATION LAB Lab Procedures: First, observe the specimens located at each station without touching it.
This is shown throughout the book when the characters think they know something about the virus and then being absolutely wrong. Another big idea is how can Ebola and other Filoviruses go from a myth to reality and back to myth again within months or even weeks. In addition, who is the natural host? The book states that viruses don’t usually kill their natural host, with that in mind, what living organism can contain this dreadful virus? Therefore, the top three main ideas in this book are, not knowing enough about the virus, how it can fluctuate in appearance, and who is its natural
They require end-user activation and can stay dormant for a period of time before activating. A less complex virus may install itself after running the first line of code on an executable. Once it is activated, it will look for other files in order to multiply, such that all the files will become infected. Depending on the virus, there are harmless as the ones displaying a picture on the screen or can be destructive as those that modify and delete files on the hard drive. Very complex viruses cannot be detected because they are programmed to
The argument that all viruses are deadly is incorrect. In the Hot Zone, Preston explained how Ebola and Marburg caused an epidemic that killed over hundreds of people and animals. In the novel, Preston also mentions smallpox and malaria. Being diseases, there are cures for all of them which overtime will eventually prove to be not deadly. Although hundreds of lives were lost against the virus, there came a cure later on.
These examples demonstrated different types of situations that would emerge when a virus breaks out. There are many ways to prevent a virus from spreading as well as many other factors that contribute it to infect people. With this in mind with enough resources and knowledge about medical treatment, a virus outbreak can be
Viruses are parasites that are only able to reproduce inside other cells, meaning they cannot survive on their own. A virus cell must find its way through the human skin and find a cell to infect (reproduce). A virus will find a host cell
Poxviridae are linear, double-stranded deoxyribonucleic acid (DNA) viruses that replicate in the cytoplasm. “Poxviridae consists of 2 subfamilies: Chordopoxvirinae, which infects vertebrates, and Entomopoxvirinae, which infects insects”. (Medscape.com, 2015) Smallpox is a double stranded, 135 to 375 kilo base DNA virus. The virus replicates in the cytoplasm of the host cell and forms B-type inclusion bodies, unlike varicella or herpes viruses which replicate in the nucleus.
So how could a virus kill and come back without living? Also, viruses tend to evolve to explain how an epidemic doesn’t happen every year, which was rejected in a lot of American schools and scientific
What is a virus? A virus is, “an infectious disease that is capable of growth and multiplication only in living cells, and that cause various important diseases in humans, animals, or plants” (“Virus”). In simple terms, this means that it is something that attacks an organism’s cells, takes over the healthy cells and creates more infected cells in return. In general, the main difference between a bacteria and a Virus is; bacteria can thrive on its own without a living host, while a virus needs a living organism to live in. Understanding how a virus works will make the Zika virus much easier to comprehend.
But some zombies can be created by viruses’ and vu do. In the last of us (video game) the zombie outbreak was from a zombie ant. When the zombie ant bite someone fungal residue on a human’s face and other parts of the body. The virus took 60% of the human’s species. If you don’t want to see people grow mushrooms out of head fallow the steps and rules that will tell how to survive the ZOMBIE APOCALYPSE!
It is a malicious codes, malicious programs or malicious software that can infiltrate or damage the computer. It can turn a computer in to a zombie, which is a machine that is controlled externally to perform malicious attacks. It often effects a large user population and harms their computer. Malware always has a damaging function (called Payload) and has different effects.
