True. An encryption scheme doesn't care what it is encrypting, be it compressed or uncompressed.
Note that an encrypted file will look like random data to most compression algorithms, so it makes sense to first compress, then encrypt, to get the maximum efficiency from the compression.
It says it in its name, replace all
Answer:
def population_density(dictionary_list):
""" this function calculates the population density of a list of countries"""
total_population= 0
total_area= 0
for country in dictionary_list:
total_population += country['population']
total_area += country['area']
population_density = total_population / total_area
return population_density
Explanation:
In python, functions are defined by the "def" keyword and a dictionary is used to hold immutable data key and its value. The for loop is used to loop through the list of dictionaries and the values of the country data and extracted with bracket notation.

The answer to this question is True.
Because you can use the same animation on any content such as text, shape, images etc in PowerPoint.
As in this question, Celia was working on a presentation and she choose the fly in animation for her slide title. She has to use the same animation for her bullet points in the slide.
You can find the fly in animation in the Animation tab, under under Emphasis group of animation. You can apply the fly in animation to any selected text, text block, shape, and or image. It is not necessarily, that one applied animation can't be applied again on the other content in the slide. However, it is noted that if you add the animation again on the content that already have the animation, then your previous animation effect will be replaced with the new one.
