Swine are vulnerable to infection by bird flu virus and human flu virus, which can both be present in an individual pig at the s
ame time. When this occurs, it is possible for genes from bird flu virus and human flu virus to be combined. If the human flu virus contributes a gene for Tamiflu resistance (Tamiflu is an antiviral drug) to the new virus, and if the new virus is introduced to an environment lacking Tamiflu, then what is most likely to occur? If the Tamiflu-resistance gene involves a cost, it will experience directional selection leading to reduction in its frequency. T/F
As long as the gene that is resistant to Tamiflu involves a cost, there is a very big possibility that it is likely to experience what is known as directional selection. This directional selection has the ability of leading to a reduction in the frequency of the Tamiflu-resistance gene. Hence, the answer to the question is True.
Zika is spread mostly by the bite of an infected Aedes species mosquit. Zika virus directly infects brain cells and evades immune system detection. Zika virus disease is generally mild, and severe disease requiring hospitalization and deaths are uncommon.
They will sever her corpus callosum in which they are nerve fibers in the brain. They allow the hemispheres in the brain to be connected and severing this is a requirement to treat her epilepsy. This will reduce the symptoms that occurs in the contribution of epilepsy for they could be one of the factors contributing to those who people who has epilepsy.
