Answer:
The brown-eyed parents must be HETEROZYGOUS to produce a blue-eyed child
Explanation:
This question involves a single gene coding for eye color in humans. The allele for brown eyes (B) are dominant over the allele for blue eyes (b). This means that an individual that is heterozygous (Bb) will phenotypically have a brown eyes.
According to this question, a blue-eyed child (bb) will be produced when two brown-eyed parents are HETEROZYGOUS (Bb) for the eye color trait. This means that each of the parent donated the recessive allele (b) to produce the (bb) offspring. Please find the punnet square attached.
Convection currents, C! The plates move in a cycle called a convection cell that forms when warm material rise, cool, and even sink.
Answer:Classification, in biology, the establishment of a system of categories on the basis of presumed relationships among organisms. The science of biological classification is commonly called taxonomy.
In most plants, the leaves are the main food factories. They capture the sun's energy with the help of chlorophyll in the leaf cells. The chlorophyll traps and packages the energy from the light of the sun in a process called photosynthesis. Leaves usually have a large surface so they can collect the most sunlight.
