Which of these statements best describes the St. Lawrence Seaway? The St. Lawrence Seaway connects the St. Lawrence River with t
he Arctic Ocean. The St. Lawrence Seaway provides an important trading route between the U.S. and Mexico. The St. Lawrence Seaway provides an important trading route for the U.S, but has little value for Canada. The St. Lawrence Seaway connects the Great Lakes, the St. Lawrence River, and the Atlantic Ocean.
The St. Lawrence Seaway is important for Canadian and U.S. trade.
The St. Lawrence Seaway connects the Great Lakes, the St. Lawrence River, and the Atlantic Ocean.
Explanation:
Saint Lawrence Seaway is a canal, canal and lock system that allows ships from the Atlantic Ocean to access the Great Lakes to the western parts of Lake Superior. The sea path is named after the St. Lawrence River, which originates from Lake Ontario and drains into the Atlantic Ocean. It stretches from Montreal to Quebec and Lake Erie, including the Welland Canal. We can say that St. Lawrence Seaway is important for Canadian and US trade. In addition, the St. Lawrence Seaway connects the Great Lakes, the St. Lawrence River and the Atlantic Ocean.
The answer would be D. Tropical Rainforest, this would be due to the abundance of rain which creates plenty of vegetation and then, more herbivores will live in the rainforest, and the more herbivores there are, the more carnivores will come to the rainforest. The canopy of the tall trees also provide shelter for countless of thousands of species of birds.
Embryonic development involves process of formation and development of an embryo. In humans, during the early stages, 10 weeks of embryonic development, all the major body organs are formed.
According to the question, mating between two populations of Rhagoletis produce hybrid flies.
This means that the two population is present in the same habitat or locality, hence they are capable of coming in contact with each other and mate. Hence, the answer cannot be Habitat Isolation.
Mating produces hybrid flies. This is possible when the gametes (egg and sperm) of the two different populations are capable of capable of coming close to each other and undergoing fusion (fertilization). Hence, there is no Mechanical Isolation.
The zygote formed by the above fertilization is capable of developing into healthy hybrid flies with normal life span. Hence, Pre-zygotic Isolation is absent.
But the hybrid flies formed are sterile and not fertile, that is, they are incapable of producing viable gametes which can undergo fertilization and produce a new offspring.Therefore, the eggs laid by the hybrid flies hatch less often. Hence, there is existence of Reduced hybrid fertility.
