There are three major forms of fossil fuels and these are coal, oil and natural gas. All three were formed many millions of years ago before the time of dinosaurs.
Plants and trees died and sank to the bottom of swamps which filled the land. The dead matter formed layers of a spongy material called peat. Over time the peat was covered by sand, clay and other minerals which turned into sedimentary rock.
As the layers of rock piled up, their weight squeezed the peat until water came out of it and it eventually turned into coal, oil and natural gas.
Are located in a specific place on a chromosome
Answer:
The correct answer will be virus.
Explanation:
The virus is the infectious agents which cannot replicate themselves. these viruses contain a protein capsid surrounding the genetic material.
The genetic material in the virus could be DNA or RNA but do not have both as single-stranded or double-stranded forms.
A virus with RNA are common in nature and an only a limited amount of RNA or DNA can fit a capsid and the capsid along with genetic material is known as the nucleocapsid.
Since the specimens show RNA but not DNA it is a virus-like Ebola, polio, measles, therefore, the specimen is virus and is the correct answer.
