what is the question?

ill give brainly pls help
can someone answer this pls??
Answer:
75% brown, 25% white
Explanation:
This question involves a single gene coding for color in chickens. The allele for brown color (B) is dominant over the allele for white color (b).
According to this question, a brown rooter with genotype 'BB' was crossed with a white hen (bb). The offsprings in the F1 generation will all possess the 'Bb' genotype and be brown colored. However, if these F1 offsprings are self-mated i.e Bb × Bb, the proportion of F2 offsprings will be 1BB, 2Bb, 1bb.
Since BB, Bb and Bb offsprings are Brown in color and bb is white in color, this means that the expected phenotypic appearance of the F2 offsprings will be:
¾ or 75% brown and ¼ or 25% white

How do weathering and erosion work together to change or build landforms
Answer:
Erosion is another geological process that creates landforms. When mechanical and chemical weathering breaks up materials on the Earth's surface, erosion can move them to new locations. For example, wind, water or ice can create a valley by removing material. Plateaus can also be formed this way.

With over 600 muscles in the body we are able to do an array of motions. What is the difference between what big muscles, like the four in the quadriceps, can do and what those like the thirty in our hands can do?
The functions of each muscle depend on its location and ability to perform specific work. For example, the masseter muscle is the strongest muscle in humans which is present in the jaw.
What is the significance of muscles?The significance of muscle is understood by the fact that these structures are linked to bones, internal organs, and blood vessels. These components are responsible for movement by their contractions.
According to the context of this question, the muscles in the shoulder region are the four rotator cuffs which significantly include the supraspinatus, infraspinatus, teres minor, and subscapularis. The four muscles in the quadriceps have to perform a different function which includes heavy weightlifting, so, they have to strongest enough.
While the thirty muscles present in the hand can do numerous functions with different levels of intensity. These muscles are not too strong as compared to masseter but are superior.
Therefore, the functions of each muscle depend on its location and ability to perform specific work.
