Willingness to take a risk and try something new
Answer:
II and III
Explanation:
A species is classified as endangered when it comes to a situation where the number of individuals within the species is so low that it might not be enough for it to reproduce properly and survive. Also, when species is listed as endangered, the chances are very high that the species will go extinct.
In order for the species to be saved, there are numerous methods that are used:
- One thing is to make the hunting of the species illegal, usually making a very strict law that would fend off anyone tempted to do so.
- Creating a special program for monitoring the species, where every individual will be tracked, constantly checked, and protected on the ground.
- Any entry into the area where the species lives to be forbidden, except for scientific goals related to the species, and even for it to have a species permit.
Unfortunately, this doesn't always have the wanted effect, and despite all efforts some species go extinct, like it is the example with several species of rhinos in the past century. On the other hand, there are species that seem to be extremely resilient, and despite having very low numbers, they manage to survive, even if they don't have any particular rise in their populations, like it is the examples of the Iberian lynx and the Balkan lynx.
Very often, the method of breeding individuals in captivity of a species that is endangered is used. This is done so that there are controlled circumstances and no danger for the offspring, thus to maximize the chances of their survival. By using this method though, special programs are needed afterwards in order to prepare the young ones for life in the wilderness, which is not always successful.
Answer:
Option: It prevents destructive flooding from the Yangtze River and produces cheaper and cleaner energy
Explanation:
The Three George Dam has been one of China's most expensive projects. The Three Gorges Dam has been the world's largest power station, which can generate about 22,500 MW. The dam also stops floods by the Yangtze River, which happens every 10 years and destroys thousands of homes.
The development of renewable resources has the goal of reducing greenhouse gasses in the atmosphere.
In the last decades there has been increased effects on the climate and atmosphere on our planet, and it is obvious that the reason for that are the human activities and the usage of fossil fuels and coal. Because of this people have started to develop and invest more and more into the renewable resources, thus step by step replacing the fossil fuels and coal, and protect the environment.
Answer:
They are used to find the distance between two hills.
Explanation:
Scale bars in a topographic map is used to find the distance between two hills.
The bar shows the relationship between ground distance and that map distance.
- When we compare the distance measured on map with the scale given, we can find the true distance on land.
- Scales are mostly used for abstracting the real world.
