Why is soil erosion important to agriculture?
Alexxx [7]

Answer:

Soil erosion causes siltation in rivers, dams, etc. In some areas, huge river deltas are formed (such as River Nile delta) because of soil erosion. Such places are good for agriculture but not good for urbanization. However, some people do not care about it, they just want to construct buildings on alluvium type soils.

If a boy exhibits a sex-linked trait that is carried on the X chromosome, what must be true?
Artemon [7]

Answer:

C. His mother carried at least one allele for that trait

Explanation:

-Men have a single allele of each gene on the X chromosome, inherited from their mother, and a single allele of each gene on the Y chromosome, from their father.

-A sex-linked trait is a trait that is controlled by a gene or an allele located on the sex chromosome.

-X-linked traits are maternally inherited from carrier mothers or from an affected father. Each son born to a carrier mother has a 50% probability of inheriting the X-chromosome carrying the mutant allele.
