The EBOLA VIRUS Disease Every few years‚ a new pandemic hits the globe and sends shivers down everyone’s spines. The latest one making headlines is the Ebola virus‚ that has infected and killed thousands of people in 5 West African countries‚ since the latest outbreak began in March 2014. So what is this disease that scientists have yet to find a cure for‚ and how do people catch it? Background & History The Ebola virus causes a serious and severe illness which is often deadly if untreated.

Deadly Invaders Project 1. A virus is an infective agent that has a nucleic acid molecule in a protective coat. They generally range in 20 to 300 nm‚ has RNA or DNA that multiplies in a cell. A lytic phase in a virus is when the conditions for infecting are favorable‚ when there are many “victim cells” and good conditions outside the cell. 2. Viruses are not alive‚ as they only have DNA/RNA and few other necessary ingredients of a cell. They lack too many things to be called living. Viruses reproduce

The rabies virus is a zoonotic virus that kills an annual 55‚000 people in countries like Asia and Africa. The amount of deaths is so high in these two countries because they’re not as advanced in medicine as us and vaccinations aren’t as easy to get there Japan is a rabie free country leading with less than 5 cases the past 50 years. The reason why Japan has almost no cases of rabies is because they have a strict policy on domestic animals making sure they have all their shots and are not infected

AIDS is caused by the human immunodeficiency virus (HIV). By killing or damaging cells of the body’s immune system‚ HIV progressively destroys the body’s ability to fight infections and certain cancers

Effects of Crossing Over in Sordaria fimicola Abstract Sexual reproduction in organisms is a cause for genetic variation. This can be seen through the process of meiosis in Sordaria fimicola because of the effects of crossing over and independent assortment that occur in meiosis I. Before performing this experiment we hypothesized that we would be able to see that crossing over did indeed occur in the S. fimicola. We tested our hypothesis by growing our own culture and observing it under a

Biology Research Task- Lucy Kerslake What causes antibiotic resistance? Antibiotic resistance occurs when an antibiotic is no longer effective against a particular bacteria‚ making that organism resistant to the effects of the antibiotic. Bacteria become resistant due to selective pressure. Those organisms which resist the antibiotic‚ and do not die from it ’s effects have a greater chance of survival within the host‚ therefore allowing them to reproduce and spread it ’s resistance to other

What is a genetically modified organism? A genetically modified organism (GMO) is an organism whose genetic material has been altered using techniques in genetics generally known as recombinant DNA technology. Viruses‚ bacteria‚ fungi‚ plants‚ and animals are all examples of organisms that have been engineered so that they contain genes from at least on unrelated organism. To create a genetically modified organism a molecule from a different source are combined into another molecule to create

DISEASE PREVENTION AND CONTROL DISEASE A disease is an abnormal condition that affects the body of an organism. It is often construed as a medical condition associated with specific symptoms and signs. It may be caused by factors originally from an external source‚ such as infectious disease. “Disease" is often used more broadly to refer to any condition that causes pain‚ dysfunction‚ distress‚ soci al problems‚ or death to the person afflicted‚ or similar problems for those in contact
