You are a carbon dioxide molecule floating in the air that is about to enter the stomata of a leaf. Tell the story of your adven
fiasKO [112]
<span>A CO2 molecule found a friendly stomata on the bottom of a leaf. As the sun rose, the leaf's cells opened up to let the molecule in through the stoma. Soon, it was moving around inside with other CO2 and water molecules. Soon, the plant--powered by the sun--began re-assembling the molecule into new forms, adding and subtracting bits with other molecules, to make sweet glucose and release oxygen into the air. A curious rabbit couldn't resist a few nibbles of the sweet leaves with their glucose, and soon the CO2 molecule, in its new form as glucose, was inside the bunny's belly, being converted into energy.</span>

What are possible negative effects of building a hydropower dam? Select the two correct answers.
MrMuchimi

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.
