1) To calculate the population density you first need to know how many <span>squirrels form that population. To calculate the number of</span><span> squirrels: 1500</span> squirrels is the capacity, so it's equivalent to 100% So how much squirrels are present in 80% of the area: 1500----100 % x----------80 % x= 1200 <span>squirrels </span> 2)Population Density equals the number of squirrels divided by the land area In the first part was calculated the number of squirrels and the exercise gives us the area in hectares so the only thing left to do is divide them. (since this exercise doesn't specify that the area needs to be in a certain measurement we can use hectares) Population Density = 1200/ 150 <span>The population density of the squirrels is 8 per hectare</span>
<span>the virus injects the genetic info. this can be RNA or DNA. retroviruses inject RNA. after injection, the host cell transcription/translation machinery is hijacked and starts making virus proteins from the viral genes.</span>
<span>the theory that the origin and phenomena of life are dependent on a force or principle distinct from purely chemical or physical forces.</span>. They don't believe in it anymore because it simply had to rely on to many factors that seemed unlikely.<span />
