Answer:
1) The alleles for homozygous brown hair will be BB.
2) The alleles for heterozygous brown hair will be Bb
3) Let's make a punnet square to check for the outcomes:
B b
B BB Bb
B BB Bb
4) The results from the punnet square depict that the phenotype of all the children produced will be brown hair.
5) The punnet square depicts that there will be a 50% probability of the child to carry the heterozygous genome (Bb) and there is also 50% probability for the child to carry homozygous dominant genome (BB).
The answer is B. Gravitational potential energy.

<span>The most obvious change due to seasonal variation is the change from summer to winter. Some animals migrate to other parts of the world, such as migratory birds. Many animals in colder climates hibernate. In both cases, the absence of these animals leads to a gap in the ecosystem. In regions with highly seasonal rainfall, the low rainfall season can lead to low flows in rivers, and a reduction of certain habitats for some aquatic organisms, such as beaver or aquatic insects.</span>
