The correct answers are B; Displacement of people living near the proposed dam and C; Lower river water levels in other areas.
Further Explanation:
The hydropower dam uses water instead of coal to generate electricity. Since they are build on the water, they will be using that source as a way to generate electricity. This will cause the water levels to be lower in some areas along the river.
When building a dam, they will need to use property that is located on the river. Many people own homes along the river banks all over the world. The company who will be building the dam will usually buy out the property owners at a fair market price. This will mean that they will have to move and leave their homes. The homes are typically torn down to make way for the dam.
In some instances, the water bills for the people in the area may be raised also since so much water is being used by the hydropower dam.

1. What happens in the process of natural selection;
<span>Natural selection is the process which organisms with variations most suited to their local environment survive and leave more offspring. Natural selection occurs in any situations in which more individuals are born than can survive (the struggle for existence), there is natural heritable variation (variation and adaptation), and there is variable fitness among individuals referred to as survival of the fittest.
2. Organisms with greater fitness generally leave more offspring than organisms that are less fit.
This is because </span><span>the organism is better adapted to their environment than the other organism. They can survive and reproduce more while individuals with characteristics that are not suited for their environment either die without reproducing or leave few offspring and are said to have low fitness.
</span>
3. Similarity and differences between natural selection and artificial selection;
<span>In both artificial and natural selection, only certain individuals in a population produce new individuals. However; in natural selection, the environment- not a farmer or animal breeder- influences fitness.</span>
4. Hutton's and Lyell's ideas are important to Darwin;
This is due to the fact that they both <span>contributed to Darwin's theory, which implies that life has been on Earth for a very long time- enough time for all this descent with modification to occur. They stated that: Deep time gave enough time for natural selection to act. For evidence of descent with modification over long periods of time, Darwin pointed to the fossil records.
5. Evolutionary tree and what it implies about all species living and extinct
</span><span>Evolutionary tree or phylogenetic tree is a diagram that represents evolutionary relationship among organisms. The evolutionary trees show the diversity of life on the idea that species change over time. They imply how all organisms are related.
6. Structure of the lion's teeth an adaptation to the lion
Adaptation involves heritable characteristic that increase an organism's ability to survive and reproduce in an environment.
The structure of lion's teeth is an adaptation to the lion because they increase the lions ability to kill prey and tear meat, making it adaptable to an ecosystem and increasing its survival. </span>
<span>The answer is A. The troposphere layer has the greatest air pressure because it is the layer that is closest to the Earth and air pressure is greatest near the surface of the Earth.
Hope that helps. :) </span>
Their safety is dangerous when they don't use a common measurement is because they don't know what are safe amounts of this dangerous chemical for them to use. Because they're using dangerous chemicals without a common measurement - this obviously puts them at risk.
