Discuss how classification systems have undergone several changes over a period of time.

With time, the classification systems have undergone numerous alterations. Aristotle made the first attempt at classification. He divided plants into three categories: trees, shrubs, and herbs.

On the other side, red blood cell presence or absence was used to categorise animals. The known organisms cannot all be categorised using this technique.

As a result, Linnaeus provided a two-kingdom classification scheme. Kingdom Plantae and kingdom Animalia are its constituent parts. However, this approach did not distinguish between eukaryotes and prokaryotes or between unicellular and multicellular creatures. As a result, there were numerous species that fell outside of the two kingdoms.

Thus, in order to classify the three kingdoms, Ernest Haeckel divided unicellular eukaryotic organisms into a separate kingdom called Protista.

Write a program that uses nested loops to collect data and calculate the average rainfall over a period of years. The program sh

babunello [35]

Answer:

In Python:

year = int(input("Years: "))

while year<1:

year = int(input("Invalid. Enter 1 or greater: "))

total = 0

for i in range(1,year+1):

for j in range(1,13):

month = int(input("Year "+str(i)+", Month "+str(j)+": "))

while month<0:

month = int(input("Invalid. Enter 0 or greater: "))

total+=month

ave = total/(12*year)

print("Months: "+str(12 * year))

print("Total: "+str(total))

print("Average: "+str(ave))

Explanation:

This gets the number of years

year = int(input("Years: "))

This loop validates the number of years

while year<1:

year = int(input("Invalid. Enter 1 or greater: "))

This initializes total to 0

total = 0

This iterates through the years

for i in range(1,year+1):

This iterates through the month of each year

for j in range(1,13):

This gets the rainfall for each month

month = int(input("Year "+str(i)+", Month "+str(j)+": "))

This loop validates the amount of rainfall

while month<0:

month = int(input("Invalid. Enter 0 or greater: "))

This calculates the total rainfall

total+=month

This calculates the average rainfall

ave = total/(12*year)

This prints the number of month

print("Months: "+str(12 * year))

This prints the calculated total amount of rainfall

print("Total: "+str(total))

This prints the calculated average amount of rainfall

print("Average: "+str(ave))
