Answer: The answer is A. Explains how organisms change in response to the environment.
Explanation: A scientific theory is an EXPLANATION of an aspect in the natural world. In other words, it just tells why something happens. Now it is not just a guess, it is well-supported by evidence and previous studies.
Now to knock out your other choices:
B. is wrong because:
A scientific theory does not predict. It can serve as a basis for a prediction, or what you call a hypothesis, but it does not predict an outcome.
C. is wrong because:
As mentioned earlier, a theory is WELL-SUPPORTED by evidence and previous research.
D. is wrong because:
A theory does not become a scientific law.
Answer:
During cellular respiration animal cells combine oxygen with food molecules to release energy to live and function. Also, cellular respiration produces carbon dioxide as a waste product. They release the carbon dioxide into the air as a waste product. Plants help animals and animals help plants.
Good luck :D
Explanation:
Answer:
The answer is D) Another biopsy from a distinct site may show a different result.
Explanation:
In molecular biology southern blot is used to detect a specific sequence of DNA. Mitochondria are energy producing organelles in the cell and they possess DNA that is inherited only from the mother. Although Southern blot is the classic method used to detect large deletions in mitochondrial DNA, it is not always sensitive enough to detect heteroplasmic deletions at low levels leading to results that are not always reliable. Heteroplasmy refers to the presence of more than one mitochondrial DNA in an individual. The presence of a mutation in the mitochondrial DNA can create an intracellular heteroplasmic mix of mutant and normal mitochondrial DNA. Cells with a higher rate of cell division like blood can yield inconclusive results in southern analysis because heteroplasmy favors wild type mitochondrial DNA. Thus, non-dividing cells such as muscle cells are preferred for the analysis.
