Task1: #Define a function called show_students which takes 2 parameters students and message #Print out a message, and then the list of students #Next, put the students in alphabetical order and print them #Next, Put students in reverse alphabetical order and print them Example Output: Our students are currently in alphabetical order. - Aaron - Bernice - Cody Our students are now in reverse alphabetical order. - Cody - Bernice - Aaron

def show_students(message, sList):    print(message)    print(sList)    print("Our students are currently in alphabetical order")    sList.sort()    output = ""    for student in sList:        output += "-" + student    print(output)    print("Our students are currently in reverse alphabetical order")    sList.sort(reverse=True)    output = ""    for student in sList:        output += "-" + student    print(output)   show_students("Welcome to new semester!", ["Aaron","Bernice", "Cody"])

Explanation:

Firstly we declare a function that will take two inputs, message and student list (Line 1).

In the function, we first print the message and the original input student list (Line 2 - 3). Next, we use sort method to sort the input list and then output the sorted items from the list using a for loop (Line 5-10).

Next, we sort the list again by setting reverse = True and this will sort the list in descending order (Line 13). Again we use the similar way mentioned above to output the sorted items (in descending order) using a for loop (Line 14 -17)

We test the function using a sample student list (Line 18) and we shall get the output:

Welcome to new semester!

['Aaron', 'Bernice', 'Cody']

Our students are currently in alphabetical order

-Aaron-Bernice-Cody

Our students are currently in reverse alphabetical order

-Cody-Bernice-Aaron

answer: when the substance contain the two parts (polar and non-polar) like soap.

explanation:

soap is produced from the basic hydrolysis of ester "saponification", it is considered as a salt of hydrocarbons. the soap molecule contains the two parts: a polar group   (-coo-na+) and a non-polar group (r-hydrocarbon part). the polar group is called the head and the tail is the non-polar group. the polar group is hydrophilic in nature (water loving) and the non-polar group is hydrophobic in nature (water repelling).the polar/non-polar nature of a substance is useful that it can dissolve the non-polar substances by the polar part and also can dissolve the polar substances by the non-polar part. it commonly used in detergents and soaps.
