we really do come in all shapes and sizes . this is true for the things we can see ( like height or hair color ) and for the thing we can ’ t see ( like average heart rate ) . it seems like every time scientists try to find something that is truly the same for all people , they end up finding endless variations .
i 'd like to know what are the differences in symptomatology related to the timing of the mosaicism ( fifth paragraph , last sentence ) ?

because some people are at higher risk for having a child with down syndrome , it can be helpful to meet with a genetic counselor before becoming pregnant . genetic counselors can help you understand the probability of your child having down syndrome . prenatal testing for down syndrome is available . this means that d...

with down syndrome , various types of uneven chromosome separation result in a person having an extra copy ( or partial copy ) of chromosome 21 . there are three main types of down syndrome : trisomy 21 , mosaicism , and translocation . trisomy 21 trisomy 21 is the most common form of down syndrome , accounting for abo...
someone with trisomy 21 could pass on down 's syndrome to their offspring , right , because some of their sex cells would have 2 copies of chromosome 21 ?

this is called nondisjunction . with down syndrome , various types of uneven chromosome separation result in a person having an extra copy ( or partial copy ) of chromosome 21 . there are three main types of down syndrome : trisomy 21 , mosaicism , and translocation .
and in a normal person who has a child with down 's syndrome , what happens to the sex cell that has no copy of chromosome 21 ?

research suggests that in most cases , the chromosome copying error happens at random , and is not caused by any harmful behavior by the parents before or during pregnancy. $ ^3 $ risk factors for down syndrome include increased age of mother during pregnancy ( 35 or older ) and already having a child with down syndrom...
non-disjunction at which phase of meiosis results in down 's syndrome , anaphase-1 or anaphase-2 ?
jean dubuffet ’ s childbirth is a particularly striking work of art , but not because it ’ s aesthetically pleasing . in fact , dubuffet intended quite the opposite . he wanted his art to disturb his viewers . perhaps , the most jarring aspect of this painting is the central image of a mother giving birth . the figure ...

could one say that the violence and disruption of wwii has influenced dubuffet to recreate this in the rough and crude brush strokes of the painting or is it simply a matter of striving to recreate an atavistic naturalism , untrained , undomesticated as dr chadwick has stated ?

their preference for landscapes , carefree figures and lighthearted subject matter reflects their desire to create an art that would appeal primarily to the viewers ’ senses . paintings such as matisse ’ s bonheur de vivre ( 1905-06 ) epitomize this goal . bright colors and undulating lines pull our eye gently through ...

similarly , while paintings such as vlaminck ’ s the river seine at chantou ( 1906 ) appear to mimic the spontaneous , active brushwork of impressionism , the fauves adopted a painterly approach to enhance their work ’ s emotional power , not to capture fleeting effects of color , light or atmosphere on their subjects ...

we talk about the potential difference between here and there . can we come up with a concept of an absolute potential difference ( an absolute voltage ) ? yes , we can , in a sense .
i ca n't understand why we have a section of absolute voltage , i mean voltage itself means potential difference so then what do we mean by `` absolute voltage '' and `` voltage '' ?

in any electric field , the force on a positive charge is $ f = q e $ . the external force required points in the opposite direction , $ f_ { ext } = -qe $ . for our specific example near a point charge , the electric field surrounding $ q $ is , $ e = \dfrac { 1 } { 4\pi\epsilon_0 } \dfrac { q } { r^2 } $ and the exte...
so , basically we said that fex=-qe=fe because the difference between them is negligible , but actually speaking , the external force is a little greater than the the electrostatic force ?

how much work is done moving $ q $ from point $ a $ to point $ b $ in an electric field ? when charges move in an electric field , something has to do work to get the charge to move . to move $ q $ , we apply a force to just barely overcome the repulsive force from $ q $ .
got another question , what 's exactly this `` external force '' that does work on the charge to move it , in case of charges moving in a circuit , what causes these charge to move from the source in the first place ?

in general , if a function $ f $ has a zero of odd multiplicity , the graph of $ y=f ( x ) $ will cross the $ x $ -axis at that $ x $ value . if a function $ f $ has a zero of even multiplicity , the graph of $ y=f ( x ) $ will touch the $ x $ -axis at that point . check your understanding challenge problem

check your understanding the graphical connection the multiplicity of a zero is important because it tells us how the graph of the polynomial will behave around the zero . for example , notice that the graph of $ f ( x ) = ( x-1 ) ( x-4 ) ^2 $ behaves differently around the zero $ 1 $ than around the zero $ 4 $ , which...

first , we see that the linear factors of $ g ( x ) $ are $ ( x-\teald3 ) $ and $ ( x- ( \teald { -2 } ) ) $ . if we set $ g ( x ) =0 $ and solve for $ x $ , we get $ x=\teald3 $ or $ x=\teald { -2 } $ . these are the solutions , or roots , of the equation .
so if f ( x ) = - x ( x - 2 ) ^2 , the line ( in the graph ) crosses at ( 0,0 ) and and touches the x axis at ( 2,0 ) ?
