6. Answer;
- Faster
Explanation;
Compared to the time in Earth's history before humans appeared, rates of soil erosion are faster.
-Soil erosion is the wearing apart of topsoil. Topsoil is the top covering of soil and is the abundant fertile because it includes the several natural, nutrient-rich minerals. Every year, around 75 billion tons of soil is disintegrated from the land—a rate that is about 13–40 times as quick as the typical rate of erosion.
Additionally, some human activities associated with building structures increases the rate of erosion
7. Answer;
-Mass movement
The process responsible for moving material downslope under the influence of gravity is called mass movement.
Explanation;
-A mass movement is the geomorphic process through which soil, sand, regolith, and rock move downslope typically as a solid, continuous or discontinuous mass, largely under the force of gravity.
-It involves the sudden movement of a block of material along a flat, inclined surface is called a rock slide or a slide.
8. Answer;
The plant roots bind the soil and regolith together.
The removal of vegetation may trigger mass movements because the plant roots bind the soil and regolith together.
Explanation;
-Vegetation removal can trigger mass wasting or mass movement as vegetation stabilizes soil. When it is removed from a slope, the slope is vulnerable to water and wind erosion.
Answer: Χ²=8.18
Explanation: In this population, the frequency of homozygote poisonous toads is:
p=0.82
For the homozygote non-poisonous toads:
q = 0.18
The frequency for heterozygote poisonous toad, we can use the Hardy-Weinberg equation: , in which, heterozygote frequency is given by 2pq
2pq = 2*0.82*0.18 = 0.3
Now, to compute the chi-square test, follow the instructions:
1) Find the observed values: in this case, they are the found frequency:
0.82 0.3 0.18
2) Find the expected values: As the question mentioned, the expected proportion is:
16 8 1
3) Subtract the observed value from the expected value:
0.82 - 16 = - 0.184 0.3 - 8 = -7.7 0.18 - 1 = - 0.818
4) Square each value from above:
(-0.184)² = 0.034 (-7.7)² = 59.3 (-0.818)² = 0.77
5) Divide each value by expected value:
= 0.0021 = 7.41 = 0.77
6) Add all the values and we will have the chi-square test:
Χ² = 0.0021 + 7.41 + 0.77 = 8.18
The chi-square test is Χ² = 8.18
