Brown eyes is dominant to light eyes. Mr. O'Ryan has blue (light) eyes. Mrs. O'Ryan is heterozygous for brown eyes. What are the
d1i1m1o1n [39]

Answer:

Brown eyes = 0.5

Blue eyes = 0.5

Explanation:

Given, B ( brown eyes ) is dominant over b ( blue/light eyes ). So,

BB = Brown

Bb = Brown

bb = blue/light

Mr. O'Ryan = blue eyes = bb

Mrs. O'Ryan = heterozygous brown eyes = Bb

Their children: Bb X bb :

      B        b

b    Bb     bb

b    Bb     bb

Half of the children will have Bb genotype and brown eyes, other half will have bb genotype and blue eyes. Hence, Kellan O'Ryan has 0.5 probability of blue eyes and 0.5 probability of brown eyes.

What are the inputs of the light dependent reactions?.
bixtya [17]

Answer:

6 water molecules (and technically sunlight/energy)

The inputs of photosynthesis are water and carbon dioxide (and energy); water is used in the light-dependent reactions, and carbon dioxide is used in the light-independent.  The water has to be there to replace the lost electrons in the chlorophyll that leave the thylakoids after being excited by the solar energy.
