I said punctuated. It was either divergent or punctuated. Reasons i think it wasn't divergent because it was within a species, didn't form to separate "groups" of rabbits. Pretty much all of them had the ear characteristics so and it happend over one generation. So a ""sudden"" evolutionary...
i HATE question 4. i had B, if there in their enclosure there already isolated. So vaccinating all animals will make sure the disease is eliminated over time from the popualtion. It says prevention so i assumed they only knew that one enclosure had the disease.
Re: Hsc 2009 bio exam
yeah but they were already isolated in there enclosure... would u isolate them again. "A disease has been identified in animals in ONE enclosure".
Re: Hsc 2009 bio exam
geeze for q 4 i had A then changed it to B. The question said the disease had been identified in one enclosure on a farm. and i didn't get why u would vaccinate all healthy animals and leave the sick ones. i dont know which is correct think its b though :)
