Which type of microscope can only be used to view non-living specimens?

Computers and Technology

Fynjy0 [20]3 years ago
5 0

Answer is D: Electronic microscope

An electronic microscope has greater resolving power and much higher magnifications. Most high-resolution electron microscope cannot be used to image living cells because the particle beam of powerful electrons used to illuminate a specimen also destroys the samples. Engineers, however, are coming up with ways to overcome this critical limitation by using quantum mechanical measurement. Quantum mechanical measurement will help avoid damage to the specimen by sensing objects remotely without ever hitting the imaged object.

A cookie recipe calls for the following ingredients: • 1.5 cups of sugar • 1 cup of butter • 2.75 cups of flour The recipe produ
True [87]

The program that asks the user how many cookies they want to make and then displays the number of cups of each ingredient is corresponds to the ingredients mentioned above.

<h3>Further explanation</h3>

Python is a general-purpose programming language. We want to write a python program that asks the user how many cookies they want to make and then displays the number of cups of each ingredient.

48 cookies = 1.5 cups of sugar + 1 cup of butter + 2.75 cups of flour, so:

def main():

   cookies = float(input("How many cookies would you like to make?\n>"))

   sugar = (1.5 * cookies) / 48.0

   butter = cookies / 48

   flour = (2.75 * cookies) / 48

   print("To make ", cookies, " cookies, you will need:\n", \

         format(sugar, '.2f'), " cups of sugar\n", \

         format(butter, '.2f'), " cups of butter\n", \

         format(flour, '.2f'), " cups of flour", sep='')

   redoQuery()  

def redoQuery():

   yn = input("Would you like to check another batch size? (y/n)\n>")

   if yn == 'y':

       main()

   elif yn =='n':

       exit()

   else:

       print("Please enter only a lowercase \'y\' or lowercase \'n\'," \

             "then press enter")

       redoQuery()

main()

The run program is shown in the attachment below.

In the following code segment, assume that the ArrayList numList has been properly declared and initialized to contain the Integ
KATRIN_1 [288]

Answer:

e. 4

Explanation:

The code segment will not work as intended if the value of the variable val is 4. This is because the while loop is comparing the value of the variable val to the value of each element within the numList. Since there is no element that is bigger than or equal to the number 4, this means that if the variable val is given the value of 4 it will become an infinite loop. This would cause the program to crash and not work as intended.
