Final answer:
The diets of the Inuit and typical Americans are different, but their similar body composition can be explained by how matter is broken down and used to build new matter. When we consume food, our bodies break down the matter in the food through digestion and assimilation. The nutrients from the food are then used to build and repair body tissues, resulting in a similar body composition despite dietary differences.
Step-by-step explanation:
The diets of the Inuit and typical Americans are different, with the Inuit consuming a higher proportion of meat compared to typical Americans. However, despite these dietary differences, the body composition of both groups is similar. This can be explained by how matter can be broken down and used to make new matter.
When we consume food, our bodies break down the matter in the food through digestion and assimilation. The nutrients from the food are then used to build and repair our body tissues, including muscles and organs. Any excess matter that is not used is eliminated as waste.
Both the Inuit and typical Americans have different diets, but the nutrients from the food are broken down to provide the necessary components for body composition. The body uses the available matter to build and maintain muscle, bone, and other tissues, resulting in a similar body composition despite the differences in diet.
