Question
Which of the following statements are TRUE ?Group of answer choicesTeratogens account for 10% of congenital malformationsSimple point mutations account for 8% of congenital malformations20% of congenital malformations have an unknown causeChromosomal anomalies account for 20% of congenital malformations
Solution
Without the specific data or source, it's hard to confirm the exact percentages. However, based on general knowledge:
-
Teratogens account for 10% of congenital malformations: This could be true. Teratogens such as drugs, chemicals, or infections can cause congenital malformations, but the exact percentage can vary.
-
Simple point mutations account for 8% of congenital malformations: This seems unlikely. Point mutations can cause congenital malformations, but they are not a major cause compared to chromosomal abnormalities and multifactorial inheritance.
-
20% of congenital malformations have an unknown cause: This could be true. Despite advances in medical science, the cause of many congenital malformations remains unknown.
-
Chromosomal anomalies account for 20% of congenital malformations: This seems unlikely. Chromosomal anomalies do cause congenital malformations, but they are not the major cause. The percentage is likely lower.
