Answer:
A
Explanation:
i guessed ona quiz and got it right.
Answer:
either RNA or DNA
Explanation:
The advancement of biomedical research techniques and molecular biology has led to the observation of the close relationship between certain viruses and some cancers in various animals. Thus, it has been shown that several DNA and RNA viruses are oncogenic in a wide variety of animals, from amphibians to primates, and there is growing evidence that some human cancers have a viral origin.
Based on this, we can conclude that oncogenic viruses can be composed of DNA or RNA.
To answer this question we need to remember quickly how the carbon cycle works, a part of the free carbon dioxide in the atmosphere is captured by plants through photosynthesis, other dissolves into water bodies, and some more remains in the atmosphere. This fixated carbon by plants passes to animals where can integrate into the soil or be released again into the atmosphere. The carbon that remains in the soul can form fossil fuels that are used by humans in the industry and released once more to the atmosphere. Therefore taking this into account we can say that that order is as follows:
Photosynthesis: Plants
Burning oil and coal: Factories
Respiration: Animals
Decomposers: Fossil fuels
