Clara is a vegan and she does not drink milk, a food advertised as a best source of calcium. But she is not worried too much sin
marysya [2.9K]

Explanation:

%DV label= 27%

1 cup of cooked collared greens= aprx 266.60 mg of Calcium

Assuming Clara is...

  • a teen, her required adequate intake (RAI)=  1300 mg/ day
  • an adult, her RAI= 1000 mg/day

For teenaged Clara

∵27 % DV= 270mg

% daily Calcium=  \frac{270}{1300}  * 100= = 20.8 ≈ 21%

=0.21

<u>21% of her daily calcium needs is in a cup of cooked collard greens.</u>

Calcium is an essential mineral required by the human body, it is involved in cell signalling, muscular function and homeostasis. Along with fats, fiber, vitamin A and C and iron, calcium makes up part of a recommended daily intake target or DV- these are integral to a balanced diet.

In humans, blue eyes are caused by a recessive allele ("b") that dilutes pigment production. BB and Bb individuals have brown ey
saveliy_v [14]

Answer:

Probability that the son will be:

color-blind = 1/2

blue eyed = 1/8

blue eyed and color-blind = 1/16

Explanation:

Mother : BbXcX

Father : BbXY

Colorblindness is X linked recessive trait hence will be caused when the son has XcY genotype.

XcX   X    XY :

     Xc    X

X  XcX  XX

Y   XcY  XY

Half of the sons will have normal vision and other half will be colorblind hence, there is 1/2 probability that the son will be colorblind.

Eye color is autosomal trait and blue color will be produced when the child has bb genotype.

Bb     X    Bb  :

   B    b

B  BB  Bb

b  Bb   bb

1/4 of the children will have blue eyes. Since half of the children are expected to be males, 1/4 * 1/2 = 1/8 sons are expected to have blue eyes.

Probability of a son being blue eyed and color blind will be :

1/8 * 1/2 = 1/16
