7. Picture of Species Food Web
8. Explanation of how the resistance could potentially affect the food web (some species will be negatively affected and some will be positively affected)
9. Explain human involvement in the resistance. How are we affecting the species? What is our role in this species' environment? COMPLETE SENTENCES
10. SURPRISE ME!!!!!!! Make this whatever you want :) make sure this portion is of educational value.
11. Make sure you ORGANIZE your page and answer all the questions the way I have taught you--complete, well-thought answers

H.I.V. stands for (H)uman (I)mmunodeficiency (V)irus.
HIV, seen as small spheres on the surface of white blood cells.
Hiv/aids and the environment
HAfter HIV enters the body, it piggybacks onto a T cell and works its way inside of that cell. Once inside, the virus completely takes over the T cell and uses it as a virus-making factory to make a lot of copies of itself. The newly made viruses then leave the T cell and go on to infect and destroy other healthy T cells as they continue to multiply inside the body. T cells invaded by the virus can no longer properly fight infections lives in the blood stream of its host. It attaches itself to a blood cell and injects it with its DNA an produces more HIV cells.
biotic factors
the biotic factors includes humans,monkeys,animals and etc.
Abiotic factors
Levels of virus remain relatively stable in blood at room temperature, and HIV may persist for at least a week in dried blood at 4°C. Blood containing HIV used for laboratory experiments is stored at –70°C without any loss of viral activity
It is known that HIV can live in needles for several days, however, it can live for several minutes outside the body.n certain conditions, the virus can survive outside the body for several weeks. Survival depends on which body fluid it is in, volume of the body fluid, concentration of the virus within it, temperature, acidity, and exposure to sunlight and humidity.Longer survival of HIV was also associated with lower storage temperature (less than 4°C); at higher temperatures (27 to 37°C) survival was not detected beyond seven days.
How it is resistant
The ability of HIV to mutate and reproduce itself in the presence of antiretroviral drugs is called HIV drug resistance. The consequences of drug resistance include treatment failure, increased direct and indirect health costs associated with the need to start more costly second-line treatment for patients, the spread of resistant strains of HIV and the need to develop new anti-HIV drugs. The extent of HIV drug resistance resulting from recent ART scale up in resource-limited countries has not systematically been quantified due to the lack of reliable data and information.
The benefits of it being resistant.
Since drug resistance was first described in HIV in 1989, great progress has been made in our understandingof its genetic basis and molecular mechanisms. Despite these advances and the introduction of many newantiretroviral drugs, resistance remains prevalent. The types of drug resistance tests and their relativradvantages and disadvantages are reviewed. How and when these tests should be used to inform HIVclinical practice and their place in anti-HIV drug development are considered.
Positives and Negatives
Negatives
The impacts of hiv/aids on the envir-onment are becoming more prominent among the longer-standing socio-economic analyses. For example, food security may be threatened as reductions in the labour force may reduce agricultural productivity, whilst poor nutrition renders people more susceptible to hiv infection1Within a few weeks of being infected with HIV, some people develop flu-like symptoms that last for a week or two, but others have no symptoms at all. People living with HIV may appear and feel healthy for several years.
Many people with HIV, including those who feel healthy, can benefit greatly from current medications used to treat HIV infection. These medications can limit or slow down the destruction of the immune system, improve the health of people living with HIV, and may reduce their ability to transmit HIV. How HIV Affects Your Body3 Your immune system has different kinds of cells that work together to fight infections. CD4 cells are one kind of immune cell. These cells make the proteins your body needs to fight germs and infections. CD4 cells are sometimes referred to as "helper CD4 cells" because they make other types of cells in the immune system work better.
When HIV enters the body, it attacks the CD4 cells. The virus takes over the CD4 cells by making copies of itself within the CD4 cell. When this happens, the CD4 cell can no longer help your body fight infections. Instead, each HIV-infected cell produces more HIV in the body.
At first, the body is able to create enough CD4 cells to make up for the cells lost to HIV. As the virus continues to take over the CD4 cells, there are fewer and fewer CD4 cells left to fight HIV in the body. Eventually, your immune system is weakened. And your body is less able to fight infection.
If the number of healthy cells in your body continues to decline, your HIV status will change from HIV positive to AIDS. Acquired immune deficiency syndrome (AIDS) occurs when the number of CD4 cells in your body drops below a certain amount. When this happens, your body can get HIV-related infections, also called opportunistic infections. For many people it takes a long time for AIDS to develop, for others it takes less time.

Human food web./ Human involvement
The HIV can be transmitted by needles,sexual contact. If an animal that a human eats is infected,then eating it will tranamit is if it is eaten raw however if the animal is cooked, this may kill it but you still might be able to get it.
How we affect it.
We affected it in that some people do not care so they go around spreading it to numerous peropl without caring. It is not cureable so that hurts alot of people.

ways we can prevent it
we can make sure we do not spread it to other people in any way if one has it. We can make sure that our partner is nor affected. we can also make sure we use protection every time with unknown partners. We can also do everything to keep needles clean and make sure the needle is clean when used.
surprising facts
33.4 million people live with HIV/AIDS worldwide, the vast majority of whom are in low- and middle-income countries. An estimated 2.7 million people were newly infected with the virus in 2008.
HIV/AIDS is the world’s leading infectious killer claiming—to date—more than 27 million lives. An estimated 2 million people die every year from HIV/AIDS
Combination antiretroviral therapy (ART) prevents the HIV virus from multiplying in the body. If the reproduction of the HIV virus stops, then the body’s immune cells are able to live longer and provide the body with protection from infections.
More than 2 million children are living with HIV/AIDS, according to 2008 figures. Most of the children live in sub-Saharan Africa and were infected by their HIV-positive mothers during pregnancy, childbirth or breastfeeding. Almost 1200 children become newly infected with HIV each day. The number of children receiving ART increased from about 75 000 in 2005 to 355 000 in 2009.
