Answer:
The cells analyzed might be a mosaic of different genomes
Explanation:
The human genome in every cell might not be the same and could give us some misrepresentation of what really happens on our genome. Chromosomal abnormalities are also a very common phenomena to be observed in human cells. For those differences in the genome of the child the test might have identified some altered cells with a type of chromosomal abnormality which was not latter identified or the abnormal cell might be also eliminated by its abnormal nature.
They both produce energy but the process is different. Aerobic respiration is when the cell produces energy using oxygen while anaerobic uses electron acceptors. Aerobic respiration also makes more energy.

kilometers, or about 30 percent of Earth's land surface
