Answer:
The answer is pp
Explanation:
Steve and Sonya's son genotype is pp. Because an inheritance of autosomal recessive disorder is with recessive allele responsible for the exceptional phenotype. In this case, Steve and Sonya are both heterozygotes, Pp, which means they both have a p allele because each one gave the boy a p, contributing to affect his son. And since we are talking about inheritance of an autosomal disorder, we know that the parents phenotypic proportions are the same.
Living things in the Biosphere.
Soils of the Tropical Rain forests. Soils here tend to be deep because the warm temperatures and often high rainfall lead to strong weathering of the parent rock to form soil. They tend to be reddish in color because of the way that the iron minerals in them respond to the hot climate. hope this was helpful <3
Because they don't need them. Cell walls, which are found in plant cells, maintain cell shape, almost as if each cell has its own exoskeleton. This rigidity allows plants to stand upright without the need for bones .
I think the answer would be B but none of them are great. Continental drift is the gradual movement of our land masses. Knowing this we can eliminate option D because it identifies buildings as a cause. A and C both discuss climate change which is not a product of continents moving. The elimination leaves option B however because these changes would occur gradually, it is unlikely that species would become invasive.
