Influenza Virus (Bird-Human) transmission
Influenza viruses have viral envelopes covering their protein capsids. The virus envelopes are derived from host cell membrane and viral glycoprotein. Functionally, viral envelopes are essential for entry into host cells. lipids are involve in attachment ,signaling, replication and budding processes.
During transmission even if the virus transmit from eukaryotic to eukaryotes cells the attachment of virus to the host cell may be different because the cell membranes of different host cells have different composition and types of lipids.
In another view virus can change their structure and composition during transmission from host to host and during different seasons.

    Viruses – A viruses is a small capsule that holds DNA or RNA, viruses, unlike bacteria are not self-sufficient and need a ‘host’ in order to reproduce, for example: ‘Human Body’. When a virus enters the body, it enters some certain cells and takes over making them the new ‘host cell’ which makes the parts the virus needs to reproduce, the cells are eventually destroyed through this process. The most common virus is the ‘common cold’ which has no cure.…

    Gender Roles in “the Odyssey”, by Homer

    Some structures of organelles are membrane bound. The Plasma Membrane is a membrane boundary of a cell, and sorts cell transport and is the outermost cell surface. It separates the cell from the external environment. The plasma membrane is made mostly of proteins and lipids, especially phospholipids. The lipids occur in two layers (a bilayer). Proteins embedded in the bilayer appear to float within the lipid, so the membrane is constantly in flux. The membrane is therefore referred to as a fluid mosaic structure. Within the fluid mosaic structure, proteins carry out most of the membrane 's functions (prokaryote and eukaryote cell structure, 2000.).…

For example, the quantitative method in this study gives the statistical data that was analyzed in the results. This approach as used makes it possible to give conclusive results. The qualitative method provides an in-depth analysis of the naturalistic form of testing for results. It allows the participants to have their point of view being put on research. Mixed method is important as it gives a broader and deeper sense of information. Further, the method provides in-depth information, and the knowledge of the problem is well articulated through the different data sets.…

    Virus is a toxin or poison. It is a microscopic organism consisting of genetic material. They cannot reproduce without a host cell. When it gets this host cell, it takes over its functions. The cells then continue to reproduce, and reproduces more viral protein. Viruses can spread from person to person, and by exchange of salvia, coughing, sneezing.…

    Lipid Vesicles: Lipid Enhances Infection

    Lipid vesicles are thought to enhance infection because when the Enteroviruses are released in the lipid vesicle there are numerous viruses within the vesicle, because of this it causes the lipid vesicles to have a higher chance of infecting a host cell and allowing the virus to survive. Lipid vesicles also help protect the enteroviruses from the infected hosts cell immune system.…

    Cell Virus Research Paper

    New viruses are being constructed in the world almost every second; they are present in the body at any given moment. The rate at which these viruses are being transmitted from individual to individual is increasing and it is becoming more harmful to every organism. The benefits that occur from host transfers are that viruses that infect organisms cause one infection; there is a less likely chance of an epidemic within the host cell. This article talks about how viruses are transmitted from host to host and how they can cause epidemic diseases. Through the environment, specific hosts, hospitable binding sites, and other factors, the spread of viruses can be controlled. Viruses that have caused epidemics in the past have had an established animal reservoir and have switched hosts to humans. By studying theses effects on viruses, it helps us to better understand viruses and how to control future epidemics in the world.…
