The statement that is an example of part of a scientific theory statement that carbon is matter and cannot be created or destroyed (option A).
<h3>What is scientific theory?</h3>
Scientific theory is a coherent statement or set of ideas that explains observed facts or phenomena and correctly predicts new facts or phenomena not previously observed, or which sets out the laws and principles of something known or observed.
A scientific theory can be said to be an hypothesis confirmed by observation or experiment.
Therefore, the statement that is an example of part of a scientific theory statement that carbon is matter and cannot be created or destroyed because it is an established fact.

Answer: This answer is for all the questions: Chargaff's rules state that DNA from any species of any organism should have a 1:1 stoichiometric ratio of purine and pyrimidine bases (i.e., A+G=T+C) and, more specifically, that the amount of guanine should be equal to cytosine and the amount of adenine should be equal to thymine.
Explanation:
Selective breeding is the traditional method for improving crops and livestock, such as increasing disease resistance or milk yield.
Genetic engineering is a faster way, which transplants genes for a desired characteristic into an organism. However, genetic engineering offers many potential benefits but carries the risk of unexpected harmful effects.
