Question

question 7
which of the following does not contribute to differences in the rate of fetal growth?
○ environmental factors
○ nutritional factors
○ racial factors
○ socioeconomic factors

Explanation:

To determine which factor does not contribute to fetal growth rate differences, we analyze each option:

• Environmental factors: Can affect fetal growth (e.g., exposure to toxins).
• Nutritional factors: Maternal nutrition directly impacts fetal growth.
• Racial factors: Race itself (as a biological category) does not inherently determine fetal growth; differences attributed to race often stem from socioeconomic, environmental, or nutritional disparities (not race as a biological trait).
• Socioeconomic factors: Influence access to healthcare, nutrition, and environment, affecting fetal growth.

Thus, racial factors (as a standalone biological factor) do not contribute to fetal growth rate differences.

Answer:

C. racial factors
