Alcohol is a teratogen that can lead to birth defect.

Question

BlackTom AI · Accepted Answer

Question restatement: The prompt asks whether the statement 'Alcohol is a teratogen that can lead to birth defect' is true or false.
Option 1: True. This statement is accurate because alcohol consumed during pregnancy can interfere with fetal development, and is classified as a teratogen. Exposure can lead to fetal alcohol spectrum disorders (FASDs), which include a range of birth defects and neurodevelopmental issues. The mechanism involves alcohol crossing the placenta and affecting cell proliferation, migration, and signaling during critical periods of development. 
Option 2: False. This option would imply that alcohol cannot cause birth defects or teratogenic effects, which contradicts well-established medical and developmental biology evidence. Numerous studies and public health guidelines show associations between prenatal alcohol exposure and structural anomalies, growth deficits, and neurobehavioral problems, making this statement incorrect. 
Summary of reasoning: The assertion in option True aligns with current scientific understanding of teratogenic risks of alcohol during pregnancy, while option False denies these well-documented effects. The key misconception in the false option would be underestimating or ignoring teratogenic potential and fetal vulnerability due to in utero alcohol exposure.
