<span>Chemical weathering occurs more rapidly in a hot and wet climate. Chemical processes like chemical weathering happens rapidly during high temperature, specifically during warm but damp climates. So, on the first question, the answer is letter A. On the second question, the statement that best describes rill erosion is letter D. Rill erosion is the removal of soil by a running water that cuts and forms small channels into a slope or streamlets.</span>
The term 2pq represented in the hardy-weinberg equation is the frequency of heterozygotes and is denoted as option D.
<h3>What is Hardy-weinberg equation?</h3>
This mathematical equation is used to calculate the genetic variation of a population at equilibrium and can be seen below:
p² + 2pq + q² = 1
where
p² is dominant homozygous frequency (AA)
2pq is heterozygous frequency (Aa)
q² is recessive homozygous frequency (aa).
The 2pq can be seen as the heterozygous frequency which is therefore the reason why option D which is frequency of heterozygotes was chosen as the most appropriate choice.
