Answer:
Lots of cons
Explanation:
It produce less current like 0.5 A. But a a simple cell can make 1.5V.
The material used to create it is very expensive.
So it's not efficient enough.
Answer:
The sedimentary rocks beneath the ocean bottoms are very thin
The answer is “Two pieces of continental crust meeting at a convergent boundary”
When two continental crusts collide, a convergent boundary is formed. Neither of the two plates subducts because they have similar density. The mountains are beginning to form as the rocks are compressed.
The answer is a. lack of income.
- - -
Impede means "stop." Not being rich does not stop the spread of culture. And by physical features, that means thing like "mountains" and "rivers", which can stop people from spreading out.
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
