A certain strain of bacteria will divide itself from 1 to 2 every to [minute].
As a result, its population can be modeled as
N (t) = No2. ---(eq 1)
N(t) is the population at time t, NO is the population at the beginning = 100, t = time you wait [minute].
You prepare 6 dishes. Each dish contains 100 living bacteria at the beginning.
Then you wait for 20 mins, freeze the first dish to stop the bacteria in the dish from growing.
Then wait for another 20 mins, freeze the second dish (i.e. the total growth time for the second dish is 40 min). Proceed to the next dish in the similar process until
all 6 dishes are done.
After counting all the dish, you collect the data between time and population as follow:
t(min)
N(t)
20
132
220
40
60
311
80
369
100
622
120
836
Find to (the time for bacteria to divide itself). Answer in [min]
Note: if you apply log function on both sides of eq 1 you get
In (N (t)) =t. n2
+ In(No).
---(eq 2)
A Hippogriff is a magical beast that had the front legs, wings, and head of a giant eagle and the
body, hind legs and tail of a horse. It is very similar to another magical creature, the Griffin, with the horse rear replacing the lion rear. A slightly different breed of Hippogriffs, living in the Rathlin Island—the northernmost point in Northern Ireland, was known to have a growth rate of 0.2 individuals per individual—year. From an initial population of N0, it grew to 35 individuals after 5 years. After 17 more years, the total population of hippogriffs in Rathlin Island rose to 1588 individuals. Solve for the carrying capacity of Rathlin Island and the initial population of the said specie.
Box the answers.
