Answer:
Not necessarily
Explanation:
There are animals in which vision and audition are more specialized than in humans, while in other species this relation fails. For example, in predatory birds, the vision clarity surpassing human eyesight, since this sense is required for effective prey capture. Conversely, in the European mole (<em>Talpa europaea</em>), which is a mammal that lives mostly underground, the vision is seriously short-sighted. These are clear examples that "the function makes the organ", ie., phenotypic features such as vision and audition are selected in the course of evolution depending on the fitness that they confer to the species in particular environmental conditions.
"To facilitate the faster movement of naval ships from the Atlantic to the Pacific" reflect one of the reasons for America's interest in the Panama Canal.
<u>Answer:</u> Option E
<u>Explanation:</u>
Panama Canal is an artificial or man-made waterway of 82 km located in transcontinental country in Central America and South America named as "Panama". France was the very first nation to start work on the canal in 1881 but after some engineering issues they eliminated themselves from the project.
In 1901 the United States leaded the project which finally resulted into inaugural ceremony of the panama canal on 15th August, 1914.The bypass, one of the largest and most complex engineering projects ever undertaken, significantly reduced the time for ships to pass between the Atlantic and Pacific oceans. Therefore it allowed them to avoid the long, risky Cape Horn path around the southernmost tip of South America via the Drake Passage or Magellan Strait.
Answer:
Answer A: A key example of biotic and abiotic protagonists is the presence of rocky structures that exist in the mountains of southern Argentina (Patagonia) that thanks to them exist the ideal temperatures for the procreation of animals such as the Patagonian condor and the possibility of form nests in these rocky structures that secure their young.
Answer B:
The explanation for this is that they have populations that increase in number and have their niches realized and constant resources necessary to develop the species in this way, considering the dominant species in the area and the one that predominates, in the case of fundamental niches. , they are necessary and even obligatory niches for many populations, which if populations do not go to them, they die, extinguish, or decrease their number, that is why in the face of this reality made up of a fundamental niche since it is fundamental to persist life of the population.
Answer c:
Two key principles are: one, maintain the equilibrium, that is why one seeks to have an environmentalist position preserving nature, and two considering that we are part of that balance but that does not give us the right to break it with environmental contamination, intervention of natural food systems and many other factors.
