What is the reason that a modern electron microscope (TEM) can resolve biological images to the subnanometer level, as opposed t

Answer:

The correct answer to the following question will be "The wavelengths of the electron beams are also much shorter or less than illumination and visible light".

Explanation:

TEM seems to be a methodology of microscopy during which a pulse of electrons is transferred to create the effect through some kind of microscope, could approach biological objects at the sub-nanometer standard, as related to hundreds of nano-meters for either the absolute best microscope with super-resolution.

Also because of the electron beam's distances, they are still much shorter or smaller than daylight and infrared light, meaning that biological objects and artifacts can be resolved.

Write a program in python to test if given number is prime or not.
Paraphin [41]

Answer:

Answer:

def main():

num = int(input("Input a number to check for prime: "))

if num > 1:

 for i in range(2,num):

  if (num % i) == 0:

   print("%d is not a prime number" % num)

   break

  else:

   print("%d is a prime number" % num)

   break

else:

 print("%d is not a prime number" % num)

 

if __name__ == "__main__":

main()

Explanation:

Solution retrieved from programiz.com.

Note, this program uses the idea of the Sieve of Eratosthenes to validate the input number by using the modulo operator to determine primeness.

The program will output to the user if the number input is indeed prime or not.

Cheers.

Why would someone make a histogram instead of a bar chart?
Natasha_Volkova [10]

Answer:

Someone can make a histogram instead of a bar chart if distributions of variables are need to be represented and if data is quantitative.

Explanation:

Histograms are drawn to represent distributions of variables whereas bar charts are used to compare various variables. Histograms plot quantitative data whereas bar charts plot categorical data.

So, someone can make a histogram instead of a bar chart if distributions of variables are needed to be represented and if data is quantitative.

The user can close all the programs if he closes the open virtual desktop true false
steposvetlana [31]

The user cannot close all the programs if he closes the open virtual desktop.

<h3>What are virtual desktops?</h3>

A virtual desktop is a computer operating system that does not run directly on the endpoint hardware from which a user accesses it.  The desktop environment is separated from the physical device used to access it.

I call it a false desktop.

It is use to separate your work activities.

Therefore, the user cannot close all the programs if he closes the open virtual desktop.

Identify different character components for a given typeface: Arial.
Shkiper50 [21]

Answer: Arial belongs to the sans serif family of typefaces. It is the most commonly used typeface, and it is the default typeface set in Microsoft Word. A character is a typographic element represented through an upper- or lowercase letter, number, or special character. Every letter of the alphabet has multiple parts that we describe with a particular set of terms. Typographers call this “letter anatomy.” The basic terms common to all letters are below:

An ascender is the stroke extending upward, going above the x-height (which is the height of the letter excluding the ascender or descender).

A descender is the stroke extending downward from the baseline (which is the imaginary horizontal line that aligns the bodies of the characters).

A bar is the horizontal stroke in the uppercase letters A, E, F, H, I, and T, as well as in the lowercase letters e, f, and t.

A counter is the blank space within the body stroke.

A bowl is a curved stroke that surrounds the counter.

A shoulder is a curved stroke beginning at the stem.

A serif is the tapered feature at the end of a stroke. Arial is a sans serif font, and it does not have tapered corners at the ends of the main strokes.
