Which of the following is true of the evolution of animal phyla and animal body plans: Which of the following is true of the evolution of animal phyla and animal body plans: Animal body plans and phyla diversified during the Jurassic period and through the Cretaceous period, from around 200 million years ago until 65 million years ago, when the Cretaceous-Paleogene extinction event halted their progress. The majority of animal body plans and phyla evolved over a comparatively short timespan in the Cambrian period around 540 million years ago in an event paleontologists call the Cambrian Explosion. Animal body plans show a slow, but constant, progression, with new body plans and new phyla evolving since the Proterozoic Era 2.5 billion years ago until relatively recent times.

Write a program in Python that asks the user to enter ten integers of their choice and return them a dictionary whose keys are the integers entered and whose values are the lists of divisors of the numbers entered. Example if the user enters the numbers: 2, 7, 11, 5, 3, 19, 14, 9, 1, 4, the program returns the dictionary: d = {2: [1,2], 7: [1,7], 14: [1,2,7,14], 9: [1,3,9], 11: [1,11], 5: [1,5], 3: [1,3], 19: [1,19], 1: [1], 4: [1,2,4]} Hints: Two functions and a Print statement # create an empty dictionary which will receive the values of typed integers # create a function that find the list of divisor for given integer # display generated dictionary d GIVEN BELOW print("The dictionary is: d = ", d)
