Answer:
Heritable traits that enhance survival will become progressively more common in succeeding generations.
Explanation:
Charles Darwin's theory of evolution developed many ideas; among them we find the "Adaptation", which describes just what the exercise explains: the "inescapable conclusion" that individuals in a population will have unequal reproductive success, so that those whose traits best enable them to survive will leave more offspring. In other words, among a species, the individuals who have the best heritable traits will be able to have more offspring, and, therefore, those traits will be more and more common in the following generations.
Answer:
To avoid Hyper-oxygenation
Explanation:
Crucian carp have the ability to increase gill surface to maximize oxygen intake, or reduce overall area when under specif circumstances. If the fish does not need so much oxygen it will cover the protruding lamellae to reduce oxygen intake and avoid Hyper-oxygenation.
NAFTA - North American Free Trade Agreement created a larger scope of free trade covering United States, Canada and Mexico.
Explanation:
Major positive impact of this agreement is that it tripled the trade profits of Canada, Mexico and United states. It also removed tariffs which weer considered to be the international barriers. It increased the economic output which resulted in economic growth up to 0.5 % every year. Also Foreign investments are attracted. US oil imports from mexico was considered to be beneficial as there were no tariffs imposed by US. This had a major impact on the economy.
The transportation costs lowered due to low gas price and the food prices were also marginalized. Each nation's government contracts became available to the major suppliers which increased competition and lowered the costs.
The negative impacts are, this agreement favored import and export industry but many labor oriented industries suffered a lot which included manufacturing, textile and electronic appliances due to which many started to migrate. The companies started to reduce their wages if they refused to work for them.
NAFTA agreement totally eliminated in doing good to the farmers. It subsidized the farm products and the farmers could not make profits due to the lower farm prices which forced them to search for many other illegal jobs. They plunged into poverty and starvation.
The next impact is the degradation of the environment in Mexico. Farmers used many chemicals and pesticides to increase the production at that short period of time which resulted in unhealthy foods and deforestation resulted in global warming. No safety standard followed by the Mexican truck transport.
