Brown eyes in humans are dominant to blue eyes. A brown-eyed man, whose mother was blue-eyed, marries a brown-eyed woman whose f
Anettt [7]

Answer:

Man: Bb

Man’s mother: bb

Woman:Bb

Woman’s father: bb

Explanation:

Brown eyes are dominant over blue eyes, so, in order for a person to have blue eyes, they must carry both recessive alleles for blue. This means the man’s mother and the woman’s father must have the genotype bb. The man and the woman on the other hand have brown eyes, which means they got the dominant brown eye trait from their other parent and will have a heterozygous genotype Bb.

A group of students wants to study the rate of photosynthesis under various conditions. They use a blender to mechanically disru
11Alexandr11 [23.1K]

Answer:

B

Explanation:

The statement that best explains the result would be that <u>the rate of photosynthesis is greatest for direct sunlight and least for the infrared light.</u>

The DPIP will normally replace and play the role of NADPH in the light reaction of the process of photosynthesis. Hence, it will become colorless as a result of reduction and the rate of photosynthesis can be monitored based on the magnitude of the disappearance of the dark blue color.

It means that the more colorless the liquid in the illustration is, the more the rate of photosynthesis. <em>The color change moved from dark blue to clear colorless under direct sunlight, from dark blue to nearly colorless under indirect sunlight, and from dark blue to slightly lighter under the infrared light.</em> <u>This clearly indicates that the rate of photosynthesis is highest under direct sunlight and lowest under infrared light with the indirect sunlight having an intermediate rate. </u>

The correct option is B.
