The correct answer is - one-half.
In the past century, the deforestation of the rainforests in the world had been devastating, and it is estimated that approximately one half of the tropical rainforests have been destroyed.
The reason for the large scale destruction of the rainforests is mainly because of clearing space for agriculture and for spaces where the cattle can graze. Unfortunately, the people that live the regions where the tropical forests are, are not well educated as to how to manage the land, and a big problem is that the soil of the rainforests is only good for 2-3 seasons, because it spends and erodes very quickly. Because of that, people just continue to clear more and more of it, thus leaving destroyed forest and destroyed soil behind them, without taking in consideration the long term effects.
Hello!
The answer to this would be true.
Have a ncie day
Well it really depends on what kind of change there is. For this I'll use a drought as an example. If a drought occurs in an area the plant life and vegetation will start to die off in that area. From there, primary consumers would run out of food. then secondary consumers, and so forth and so on. it'd be like putting a cow in a field of dirt with no food and a large bucket of water. Eventually the cow will die of starvation. Now apply this to all of the animals in that ecosystem.
Answer: Mutation
Explanation: Mutation is a change in DNA sequence, it may occur due to error when the DNA is copied or it can arise from various environmental factors such as exposure to chemicals, UV radiation, Highly infectious microbes.
Mutation maybe spontaneous. Acquired mutations occur at some point in a person's life and are present only in certain cells, not in every cell in the body while some may target a tissue, an organ or an entire system.
