ASB/ BIO 250 Exam 2 Questions With
Complete Verified Solutions.
High virulence pathogens like cholera would have been very common and spread well in highly dispersed
hunter gather populations - Answer False, population densities were too low
Zoonotic diseases are usually very low virulence in humans and do not cause many fatalities - Answer
False, because there is no history of coevolution
The virulence transmission trade off is - Answer When the virulence of a pathogen impacts the host
ability to spread the pathogen
Two fold cost of males - Answer 1) Asexual females can reproduce faster
2) Only pass on half of genes
This makes males a dead end
When are we more likely to see sexual reproduction - Answer When the environment is unstable, if
there are lots of parasites and pathogens then reproducing sexually helps so that they don't get the
"key" to our immune system
Comensal relationships are where: - Answer one organism benefits from the other without impacting
the other
Peto's paradox examines cross species differences in autoimmune disorders - Answer False
Li-Fraumeni syndrome is when an individuals has - Answer 1 copy of TP53 and a high probability of
cancer
Autoimmune disorders are: - Answer more common in women because their immune systems are
down regulated
, Which of the following is not considered a transmissible cancer: - Answer Osteosarcoma
innate immunity - Answer Natural immunity that all species have that will target any pathogen or
parasite very fast and aggressively
ex: inflammation, skin
Adaptive immunity - Answer Jawed Vertebrae's only
Measured response based on previous exposure since your body recognizes this parasite or pathogen
will therefore find specific ways to fight it
If you do not have any previous exposure it will take 2 weeks for this to kick in
Ex: B cells, T cells, killer T cells, lymphocytes
Herd immunity - Answer When enough people in a population have immunity so that the virus cannot
spread
How many people need to have immunity is affected by R0
1918 pandemic - Answer H1N1 influenza
Hemagglutinin - Answer used in adherence and penetration of host cell
Neuriminidase - Answer used to break free from cell membrane during budding
antigenic shift - Answer When influenza viruses swap H and N
Ex: H1N1 and H5N4 influenza both enter a cell, they come out H1N4 and H5N1
