Answer:

The correct answer is - option D. Soil erosion.

Explanation:

Soil erosion is a normally happening process that has an impact on all landforms. In common agriculture soil erosion alludes to the removing or disintegration of a field's top layer by the normal physical powers of water  

Running water is the main source of soil erosion since water is plenty of quantity and has great power. Exercises that eliminate vegetation upset the ground, or permit the ground to dry are exercises that expand disintegration.

Thus, the correct answer is - option D. Soil erosion.

Answer:

D. Soil erosion

Explanation:

Soil erosion may be defined as the displacement of the upper surface layer of soil. In other words, soil erosion may refer to the wearing away of the earth's topsoil by some natural physical forces. This natural forces are rains, wind, ice, etc.

It is a form of soil degradation.

Thus, when the top surface of the soil is washed away by heavy rainfall and floods, it is called soil erosion.

An individual who is heterozygous for two linked genes has the genotype AB/ab, which means that the A and B alleles are in one c
Makovka662 [10]

Answer:

a and d

Explanation:

<em>Among the products of meiosis listed, aB and Ab would be the recombinant types because recombinant gametes are gametes that are unique from the haploid gametes that made up the diploid cell. </em>

A and B alleles are on a particular chromosome while a and b alleles are on another chromosome. During the process of gamete formation/meiosis, the possible gametes are;

  • AB
  • ab
  • Ab
  • aB

<em>While the first two gametes are parental (because they made up the original diploid cell), the last two gametes are recombinant gametes.</em>

Hence, from the list of options, aB and Ab are the only recombinant types.

<em>The correct options are </em><em>a</em><em> and </em><em>d</em><em>.</em>

A certain buffer is made by mixing a weak acid HA and its conjugate base A–. When HA is present at a concentration of 0.5 mM and
MAVERICK [17]

Answer:The ratio of the concentrations of HA  and A^- when the buffer has a pH of 7.02 is 0.69

Explanation:

The dissociation constant for formic acid = K_a=1.8\times 10^{-4}

Concentration of HA= 0.5 mM

Concentration of A^-= 0.1 mM

pH = 6.16

First we have to calculate the value of K_a.

Using Henderson Hesselbach equation :

pH=pK_a+\log \frac{[A^-}{[HA]}

Now put all the given values in this expression, we get:

6.16=pK_a+\log (\frac{[0.1]}{0.5})

pK_a=6.86

To calculate the ratio of the concentrations of HA  and A^- when the buffer has a pH of 7.02.

Using Henderson Hesselbach equation :

7.02=6.86+\log \frac{[A^-]}{[HA]}

7.02=6.86+\log \frac{[A^-]}{[HA]}

\frac{[A^-]}{[HA]}=1.44

\frac{[HA]}{[A^-]}=0.69

Thus the ratio of the concentrations of HA  and A^- when the buffer has a pH of 7.02 is 0.69
