|
|
Term
|
Definition
| One of the fastest evolving entities known. It reproduces sloppily, accumulating lots of mutations when it copies its genetic material. One single virus can spawn billions of copies in just one day. To fight HIV, we must understand its evolution within the human body and then ultimately find a way to control its evolution |
|
|
Term
| Why does HIV evolve drug resistance, antigens and antibodies? |
|
Definition
| The asymptomatic phase is characterized by low levels of virus and high levels of T4 cells and antibodies —this phase can last 10 years or more, depending on health of patient and their access to drugs. During this phase, the virus evolves into different variants |
|
|
Term
|
Definition
| an inference based on four observations: individuals within a populations vary, Some of the variation can be passed on to offspring, Populations produce more offspring than will survive, The organisms that best “fit” the environment survive and pass on their genes. |
|
|
Term
|
Definition
| the relative survival and reproduction of one variant compared to others in the same population |

| density dependent, density independent |
|
|
Term
| density dependent factors |
|
Definition
| cause growth rates to slow. examples: food supply, risk of infectious diseases, increased risk due to waste accumulation |
|
|
Term
| density independent factors |
|
Definition
| limit growth. example: severe weather, catastrophes, interference by man |
|
|
Term
