Explanation:

Question 13 (Fill in the Blanks)

Step 1: Analyze the first blank

The sentence is about something crucial for brain and spinal cord. From the word bank, "folate" is a nutrient important for neural development. So first blank: folate.

Step 2: Analyze the second blank

After "for the", we need a noun related to development. "formation" fits as it's about the formation of brain and spinal cord. So second blank: formation.

Step 3: Analyze the third blank

"cord" here is "spinal cord", so third blank: spinal.

Step 4: Analyze the fourth blank

"Insufficient ____ of folate" - "amounts" makes sense (insufficient amounts). So fourth blank: amounts.

Step 5: Analyze the fifth blank

"serious birth ____" - "defects" (birth defects). So fifth blank: defects.

Step 6: Analyze the sixth blank

"neural ____" - "tube" (neural tube defects). So sixth blank: tube.

Environmental factors are external influences. Age of mother (biological, not environmental), ethnicity (genetic/cultural), genetic diseases (genetic), heredity (genetic) are not environmental. Alcohol consumption, certain chores/activities, cigarette smoke, exposure to hazardous chemicals are environmental.

Nicotine from e - cigarettes and tobacco affects fetal development (e.g., growth, brain development), so the statement is false.

Answer:

folate; formation; spinal; amounts; defects; tube
