I believe the polysaccharide that provides rigidity and strength in plants would be cellulose. As this is one of the essential components found in the cell wall of plant cells.

Answer:

cellulose

Explanation:

Cellulose can be defined as the polysaccharide that provides plant stiffness and strength. Cellulose stands out for being an insoluble carbohydrate and resistant to various chemical reactions. Moreover, it is the major component of the plant cell cell wall, representing about 30% of the dry mass in primary walls and 50% to 80% in secondary walls.

Cellulose is part of the constitution of the cell wall. Here it ensures stiffness as it forms a large system of interwoven fibers. Although it is formed by the same starch compound, cellulose is not used as an energy source for the vegetable.

Only some organisms are capable of breaking down cellulose molecules for their use, such as bacteria, fungi and some animals. In ruminants, cellulose is used as a source of energy due to the presence of microorganisms in its digestive tract that can break down this product.

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
