Answer:

The program in Python is as follows:

#1

for i in range(10):

   print("MrRoyal",end=" ")

print()    

#2

for i in range(1,50,2):

   print(i,end=" ")

print()

#3

for i in range(0,101,5):

   print(i,end=" ")

print()

#4

i = 1

while i <=10:

   print(i,end =" ")

   i+=1

#5

myfile = open("People.txt", "r")

eachLine = myfile.readline()

while eachLine:

   print(eachLine)

   eachLine = myfile.readline()

myfile.close()

Explanation:

The program in Python is as follows:

Program #1

This iterates from 1 to 10

for i in range(10):

This prints the name for each iteration [modify to your name]

   print("MrRoyal",end=" ")

This prints a new line

print()    

Program #2

This iterates from 1 to 49 with an increment of 2

for i in range(1,50,2):

This prints the odd numbers in the above range

   print(i,end=" ")

This prints a new line

print()

Program #3

This iterates from 0 to 100 with a step of 5

for i in range(0,101,5):

This prints every 5th number

   print(i,end=" ")

Print a new line

print()

Program #4

This initializes the number to 1

i = 1

This opens the file in an append mode

f = open("myfile.txt", "a")

This loop is repeated from 1 to 10

while i <=10:

This writes each number to the file

   f.write(str(i))

Increment the number by 1

   i+=1

Close the file

f.close()

Program #5

This opens the file in a read mode

myfile = open("People.txt", "r")

This reads each line

eachLine = myfile.readline()

This loop is repeated for every line

while eachLine:

Print the content on the line

   print(eachLine)

Read another line

   eachLine = myfile.readline()

Close the file

myfile.close()

Answer:99

Explanation:  Last summer, my family and I took a trip to Jamaica. My favorite part of the trip was when we went to a place called the Luminous Lagoon. We ate dinner and waited for the sun to go down. Then we boarded a boat and went out into the lagoon. That’s when the magic started.

At first we could not see very much in the darkness except for the stars in the sky. After a few minutes, however, I noticed some fish swimming in the water. They didn’t look like ordinary fish. These fish were glowing! Our guide explained that the glow came from tiny creatures in the water called dinoflagellates. These little animals are not visible to us, but their bodies produce light using something called bioluminescence, just like fireflies. There are so many of these creatures in Luminous Lagoon that the water around them seems to glow.

After our guide explained these facts to us, he told us to put our hands in the water. I was not sure if it would work, but I tried it. When I did, my hand looked like it belonged to a superhero! It was glowing bright blue. I hope someday I get to return to the Luminous Lagoon. The lights in the water were much more entertaining than the ones in the sky.

Problem:

audio

The Greek prefix dinos- means “whirling” and the Latin root word flagellum means “whip”. What does dinoflagellate most likely mean as it is used in the passage?

audio

the production of light from an organism’s body

audio

the study of creatures that live in the ocean

audio

to move around underwater water like a fish

audio

an organism with a whip-like part it uses to move around in the water

Given the lists list1 and list2, not necessarily of the same length, create a new list consisting of alternating elements of lis
tester [92]

Answer:

The following code is written in Python Programming Language.

Program:

list1=[1,2,3]

 # initialized the list type variable

list2=[4,5,6,7,8]

  # initialized the list type variable

list3=[]

   # initialized the empty list type variable

for j in range(max(len(list1), len(list2))):   #set for loop

 if j<len(list1):

  #set if statement

   list3.append(list1[j])

  #value of list1 appends in list3  

 if j<len(list2):

   #set if statement

   list3.append(list2[j])

  #value of list2 append in list3

print(list3)    #print the list of list3

Output:

[1, 4, 2, 5, 3, 6, 7, 8]

Explanation:

Here, we define three list type variables "list1", "list2", "list3" and we assign value in only first two variables "list1" to [1, 2, 3] and "list2" to [4, 5, 6, 7, 8] and third list is empty.

Then, we set the for loop and pass the condition inside it we pass two if conditions, in first one we compare the list1 from variable "j" inside it the value in list1 will append in list3, and in second one we compare "j" with list two and follow the same process.

After all, we print the list of the variable "list3".
