Answer:
The process of creating a metamorphic rock is a chemical change because we are changing one rock into a whole new different type of rock.
Explanation:
Remember a chemical change is changing the core basis of what something is. Common example of a chemical change is burning wood, when you burn wood that wood turns into ash, which means it's no longer wood.
In this case metamorphic rocks are usually formed by intense heat and pressure, which converts the rock into a different type of rock.
To conclude, metamorphic rocks are formed by intense heat and pressure, which converts a rock into a different rock. "The process of creating a metamorphic rock is a chemical change because we are changing one rock into a whole new different type of rock."
Hope this helps.
Scientific investigations that involve some kind of testing will make use of observations. generally speaking making observations is the first step of the scientific method.
Answer:
Stephen is not his biological father.
Explanation:
DNA fingerprinting is a technique use to determine the DNA sequence of an individual organism. Short tandem repeats are unique among the individuals ans used to identify the individual in population.
The George DNA fingerprinting shows that he has STRs length of 6 and 7. Stephen's STRs does not match with his son George whereas Mary shows some similarities with George STRs. This indicates that Stephen is not the biological father of George because the biological father's STRs must match with the children STRs.
Thus, the correct answer is option (a).
