You can observe the picture, it is potato and you can observe the buds.
An essay usually has 5 paragraphs, intro three body’s, and the conclusion so whatever your topic is about you would introduce it then go into it for the three paragraph and then conclude your essay.
<u>It helps the writers visualize the inside of a black hole. </u>
<em>The other options can described bluntly and scientifically with just names and numbers. </em>
If the writer were to use more formal writing to describe things so abstract like a black hole, it would be hard for the common reader to understand.
____________________________
for example,
The black hole looks like a giant vacuum of nothingness (informal)
The black hole is like a mass whose Schwarzchild radius is outside of itself (formal)
Which is easier to understand? Most likely the first one because of the use of informal language and writing.
Hope I helped!
