The right answer is A.
The Hardy-Weinberg principle is a theory of population genetics, which postulates that within an (ideal) population, there is a balance of allelic and genotypic frequencies from one generation to the next.
For this equilibrium to be achieved, there must be no evolutionary forces such as mutations, migration, genetic derivatives, natural selection, the founder effect ...
Answer:
Due to presence of ocean near it.
Explanation:
The heat capacity of water is higher than soil means that soil quickly heats up at day time and cool down at night whereas, water takes more time to heat up and cool down so that's why those areas present far from ocean observe high fluctuation in day and night temperatures due to quickly heat up and cool down as compared to those areas present near water such as coastal areas which takes more time to heat up and cool down..
In the winter, cold, dry air masses tend to dominate the central and eastern United States as cold winds blow from the northwestern Canadian prairies. In summer, the warm southern winds blow moist, hot air into the eastern and central US, leading to days of high humidity and sultry conditions. In spring and fall, moving low and high pressure areas pull alternating warm and cold air masses across a given area, leading to a lot of variability in day-to-day weather.
Answer:
A topographic profile or topographic cut is a representation of the relief of the terrain that is obtained by cutting transversely the lines of a topographic map. Each contour line can be defined as a closed line joining relief points at equal height above sea level.

Answer: True</h3>
Healthy top soil is needed to grow crops, which in turn some of it becomes food. Erosion is the process in which top soil is carried away by the wind or rain water (depositing it into nearby lakes or streams). Without this top soil, farming becomes more difficult and crop yields likely decrease. In some cases, no crops can be grown at all. An extreme example of soil erosion, specifically wind-driven soil erosion, is the 1930s dust bowl during the Great Depression. This occurred due to over-farming and it led to massive dust storms. In turn, it caused many farmers to leave the area.
