Answers

The one that doesn't exemplify prose literature would be:

C). An epic poem

What is prose?

In literature, "Prose" is described as the form of writing that is not restricted by metrical structure or construction and aims to communicate an idea or story simply.

The one that doesn't exemplify prose would be 'an epic poem" because it carries a quite formal pattern using the verse form.

Since the verse form is more poetic and hence, it doesn't exemplify 'prose.'

Thus, option C is the correct answer.

Which reason best explains why living things need carbon? Carbon is a source of energy. Carbon reduces global temperatures. Carbon is an important solvent. Carbon is everywhere.

Answers

The answer is Carbon is a source of energy. 

Plants absorb carbon dioxide and make carbohydrates in a process of photosynthesis. Carbohydrates have many C-H bonds which breaking down releases such amount of energy. Also, lipids are the macromolecules with the highest number of carbon-hydrogen (C-H) bonds, so they contain more C-H bonds than carbohydrates. So, carbon is the part of macromolecules containing potential energy in the form of C-H bonds. At the end, carbon is the source of energy.

People with head colds may have difficulty tasting foods. Explain why this happens. Help please.
