correct ans is 84.
Explanation: the original population size of the bee colony is 75
as per condition ,15 bees are births so ,75+15=90
and 8 bees are death ,so 90-8=82
3 bees are emigrants , so 82-3=79
and 5 bees are immigrants , so 79+5=84.
D Questi Question 3 Determine the size of a colony of bees after the following changes...

More Calculating Population Size Populations of any organism can be analyzed mathematically. Population biologists are interested in characteristics such as doubling time, growth rate, carrying capacity, and total population at the end of a given amount of time. These calculations depend on such variables as birth and death rate, immigration and emigration, and initial population size. Use the following formulas to find the population size for each of the...

Question 2: Honeybee Colony Collapse Disorder The fitness of honeybee colonies has been declining in recent years, but the reason is unknown. A bee physiologist investigated the effect of mite parasites on the effect of colonies. She used a special chemical called MiteOff that reduced treatment groups of 10 hives each Treatment 1: no MiteOff - resulted in the most mites d parasites. Individual hives were randomly allocated to three Treatment 2: low levels MiteOff- resulted in...

Continue from the previous question, modify the following in the
IP_address class. :
add a method named get_statistics(). The get_statistics()
method return a list of all statistics data (i.e. the ip address,
total sum of all packet-size, total frequency, average of all
packet-size)
For example, consider the following code fragment
ip_key = '192.168.0.24'
data_list =[(0, 84), (1, 84), (2, 84), (3, 84), (4, 84), (5, 84), (6, 84), (7, 84), (8, 84), (9, 84), (10, 84), (11, 84), (12, 84),...
