Answer:
a) Yes! the American chestnut tree is a native species. The American chestnut tree was present before the Europeans arrived in North America in the 1600s. Since a native species has been defined as any species that was present in North America before the arrival of the Europeans, then it is a fact that the North American chestnut tree is a native species.
b) The chestnut blight is an invasive species that is native to east East Asia, and was accidentally introduced into North America around the early 1900s, when the Japanese chestnut was commercially cultivated in the United States.
c) Invasive species tend to proliferate at a very high rate because they lack some natural constraints in the new environment such as natural predators, competition, and as in the case of this chestnut blight; the host has no natural defense mechanism against them. These conditions allow them thrive more than they would in their natural environment, unchecked
d) Yes, I agree with this idea, albeit to some extent. The development of hybrid chestnut resistant to the chestnut blight will possibly return the forests back to how it was before the Europeans arrived in the 1600s, but the genetic conservation will be altered, since these new trees will be an hybrid of the old trees, and the forest won't truly be as it was before the 1600s
Hello. This question is about the article "Livestock-Handling Related Injuries and Deaths".
Answer:
"It is estimated that about 30 farmers are killed each year from contact with farm animals, primarily horses and cattle."
Explanation:
The above sentence is the one that best supports the claim that docile farm animals, such as cows and horses, injure many people each year. This is because the sentence shows a statistical data, carried out through a research survey, which proves the author's statement. This shows that handling these animals has a risk, even if they are seen as docile and peaceful, since they have strong physical strength and lack rationality.
