In which location would the rate of soil erosion most likely be higher than the rate of soil formation?
xz_007 [3.2K]

Answer:

C. A steep slope

Explanation:

Erosion is the removal of the top layer of the earth or the gathering of lose weathered materials from rock surfaces.

Agents of erosion are wind, water, glacier and gravity.

Along a very steep slope, erosion is highly rife and very prevalent to the extent that everything there is washed away to be deposited at the bottom of the slope or where gradient is more gentle.

On a steep slope, materials moves rapidly and gravity is very great. When these factors are coupled with the prevailing conditions in a place, little to no deposition occurs for soil formation.

Jill is heterozygous for gene A and is going to have a child with Jack, who is homozygous recessive for gene A. Which of the fol
Igoryamba

Answer:

D. Aa

Explanation:

Given:

Jill (mother) is heterozygous for gene A --------- i.e Jill = Aa

Jack (father) who is homozygous recessive for gene A-------- i.e Jack = aa

Now if both cross and fertilization occurs, we have:

         A          a

a        Aa        aa

a        Aa        aa

The offsprings are (Aa, Aa, aa, aa)

Nondsijunction is the inability of homologous chromosomes to seperate properly during cell division. Now, we were told that this fertilization undergone nondisjunction in meiosis 1. Hence, both homologous chromosome move into the same daughter cells instead of different daughter cells because separation of homologous chromosome does not occur properly.

Therefore the result of these fertilization of a normal haploid sperm with an egg that had undergone nondisjunction in meiosis yields offspring with genotype Aa of their Mother (Jill).
