Answer:
Cohesion is an attractive force between same kind of molecules while adhesive force exists between different kinds of molecules. When water moves inside vascular tissue they contain cell sap. It is these two forces which keep materials in cells and water can easily move them to different parts where they are necessary.
The correct option is, (B) the value of q is positive.

What is photosynthesis?</h3>
- It is a chemical process or reaction that occurs in green plants or living creatures. During this process, carbon dioxide combines with water in the presence of sunshine to produce glucose and oxygen.
- As we all know, photosynthesis cannot occur in the absence of sunshine.
- As a result, the photosynthesis reaction is an endothermic reaction in which energy or heat is supplied to the system.
- This implies that the value of 'q' will be positive. If the system produces heat, the value of 'q' is negative.

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
