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.

Answer: 3. gravitropism
The movement of plants in response to stimuli is called as tropism. Plants respond to different stimuli like light (phototropism), water present in the soil (hydrotropism), gravity (gravitropism) and touch (thigmotropism).
Gravitropism refers the growth and movement of plant parts with respect to the force of gravity exerted by earth. The roots shows positive gravitational tropism because they are growing towards earth gravity. The shoots or stems shows negative gravitational tropism because they are moving or growing against the gravity.
Correct answer: A). Forecasting weather
A weather radar is an instrument that is used to locate precipitation, calculate its motion and determine the type i.e hail, snow or rain. It sends electromagnetic energy pulse into the atmosphere. If that pulse of energy interacts with something, then it reflects back the energy, which can be sensed by the weather radar.
Nowadays, most radar used are Doppler effect, which has dual polarization, it determines that movement is toward or away from the radar.
Hence, the correct answer would be option A.
Geologic time is divided into units based upon types fossils found in each area .
I hope that's help !
I think its D but I'm not sure
