The correct answer to this open question is the following.
Although the question does not provide any options, we can answer the following.
Cattle on an open range, in some areas, may compact fragile soils while grazing. This can damage plant roots, leading to fewer, smaller plants, which may in turn cause cattle to graze more and work harder to obtain food. This is an example of a positive feedback loop.
This term is used to transmit the following meaning: the transformation of the ecosystem; from its traditional balanced state to a different situation due to the external circumstances that affect it. Although the external influence could be minor, it has a direct effect on the ecosystem of the place. It can be the result of the consequences due to a determined cause.
Airplanes brought several changes to our societies, lives and environment. Within the pros of this new mean of transport we can find the increase of the speed in which we travel and goods reach another shore. This affected positively the price of merchandises, which became easier to obtain around the world. What in the past was limited to be transported by land or across the sea, with the risk of never arriving, now it is very easy to obtain. Of course that they also opened a lot of new job opportunities for quite a few people. New careers were created and now a lot of people profit from this industry. Last but not least is the industry of tourism. Travelling has become much easier and practical since planes began to transport us.
On the other hand, the impact on the environment was not as good as in the others. Planes consume, and realease in the atmosphere, fosil fuels. This is limiting our natural resources at an incredible speed, apart from the fact that it contributes negatively to the matter of pollution.
I would say that it is the third one.
Farmer joe only breeds the largest hogs, the fastest horses, or the cows that give the most milk. this is an example of artificial selection.
The process by which humans select individual organisms with specific phenotypic trait values for breeding is known as artificial selection. If the selected trait has additive genetic variance, it will respond to selection, i.e., the trait will evolve. All of our domesticated species, including crop plants, livestock, and pets, are the result of selective breeding for desirable traits such as hardy seeds and fruits, increased meat and milk production, and docile behavior.
Although the earliest artificial selection was unintentional, it evolved into a sophisticated science of plant and animal breeding; indeed, much of the field of quantitative genetics was developed to improve breeding programs.
