We know that height in humans is a polygenic trait because it has a lot of variation. The height gene is controlled by at minimum three genes with six different alleles. If all of these alleles are dominant for the tall gene you will be tall if you are dominant for the short gene you will be short if there is no clear dominance between the two genes you will fall somewhere  in the middle.

Answer:
The correct answer is <em><u>"Mechanized plows allow larger areas to be farmed by a single farmer."</u></em>
Explanation:
Mechanized plows allow large areas of land to be plowed quickly. A further benefit is that mechanized plows do not fatigue as people and animals do. Because of this, mechanized plows help contribute to the increasing size of modern farms.
