Here's your shmoop du jour brought to you by lamaze classes [Man teaching lamaze class]

00:07

the instructor can't figure out why expecting couples keep enrolling

00:10

He figures if they really like a good maze okay here's our question which of the

00:15

following is an environmental prenatal influence and here your potential answers

00:19

....so what's this question asking well there are two

00:24

types of prenatal influences environmental and genetic basically [Pregnant woman]

00:28

influences that are inherited genetically or those affected by things

00:31

physically done to the unborn baby a classic nature versus nurture situation

00:36

and not the classic nature versus nurture mind you that was Bob nature [Boys boxing in a ring]

00:40

versus Harry nurture 13 rounds in 1954 catch it on ESPN Classic the next time

00:45

you get a chance okay.... let's take a look at mother's eye color

00:48

well unless we're talking about those tacky contacts there is something that's

00:52

genetic unless you happen to actually be born with cat eyes then you might be [Baby with the Mother and baby opens eyes]

00:55

destined for life of crime-fighting but we're pretty sure that's impossible so

00:59

we'll knock out A.. How about Pop's blood pressure....

01:03

the blood pressure itself can be influenced by environmental [Doctor taking mans blood pressure]

01:07

factors like diet or stress or taxes a father's blood pressure is genetically

01:10

inherited and would not be an example of a prenatal environmental influence though if

01:15

you're that rare cat eyed crimefighter who knows what you're doing to [Catwoman crawling on a tree branch]

01:19

your dad's blood pressure. Dad worries about you out there...

01:23

Anyway we can forget about B okay so how about family history of heart disease

01:26

well this is just like last one heart disease like blood pressure can be

01:29

influenced by environmental factors but both are also used to determine the risk [Man's heart beating]

01:33

you'll have for strokes and heart disease respectively there's actually a

01:36

lot of similarities between these two don't tell them that they like to think [Heart disease and blood pressure stood next to each other]

01:40

of themselves as individual but one undeniable similarity neither one is

01:43

correct answer to this question that just leaves two answers D and E.. Did

01:47

someone forget to lift the needle because it sounds like a broken record [Person puts needle on record disc]

01:50

here Mothers asthma like Mother's eye color Father's blood pressure and family

01:54

heart disease before it is something one inherits genetically not a prenatal

01:58

environmental factor so we can get rid of D which leaves us with answer E

02:01

moment of truth, unlike all that came before it is Mothers smoking a prenatal

02:06

environmental factor ding ding ding we have a winner chicken dinner [A chicken]

02:11

Mom's bad habit unlike the other four answers is something physically done to

02:15

the unborn child rather than something passed along genetically in this case

02:19

when Mommy dearest smokes foreign chemicals enter the womb and in case you [Image of baby in womb and chemicals spread]

02:23

missed the first day of stupidly obvious facts 101 those smoking chemicals are

02:28

not good for the baby almost everything the Mother ingests ie food, drink,

02:32

medication, etc travel through the placenta to the fetus and can thus be

02:36

considered prenatal environmental factors maternal stress can also

02:40

influence the health of the child fetus so remember it's Lamaze class not law-

02:45

maze class take shmoops word for it they're no picnic... [Pregnant woman in a maze]
