Physical weathering, also known as disaggregation or mechanical weathering, refers to the category of procedures, which makes the disintegration of rocks in the absence of chemical modification. In general, the mechanical weathering takes place due to the build-up of pressure within the rocks.
However, the rocks can also get worn away by a procedure known as abrasion. Abrasion refers to the disintegration of rocks due to friction.
The answer is: <span>A- Genes for body and wing size were on the same chromosome and inherited together</span>
The correct answer is option:
The peak of the bell curve has shifted to the right, with a greater frequency of crickets with long legs and a lower frequency of crickets with short legs.
The given condition would lead the directional selection of the crickets with long legs. Directional selection leads to shifting of curve in one direction, which is more suitable.
The crickets with short leg get easily caught by predators, so, after sometime, there would be a decrease in number of the crickets with short leg. At the same time, the crickets with long leg would manage to save themselves and their number would comparatively increased.
