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.

If a small droplet of ordinary fat molecules is suspended in water, the fat molecules form a "ball of spaghetti" with no particu
kolbaska11 [484]

Answer:

Option 1, a charged end and a noncharged end

Explanation:

Complete question

If a small droplet of ordinary fat is suspended in water, the fat molecules form a "ball of spaghetti" with no particular orientation. But if a droplet of phospholipid molecules is put in water, all the molecules point outward, toward the water. Phospholipids are forced into this orientation because phospholipids have _____

  1.  a charged end and a noncharged end
  2.  three fatty acid molecules, all pointing in different directions
  3.  two fatty acid molecules pointing in different directions
  4.  both a saturated fatty acid and an unsaturated fatty acid
  5.  two charged ends

Solution

The structure of phospholipids consists of the following groups and molecules –  

a) A glycerol molecule  

b) Fatty acids (2 in numbers) – It is hydrophobic as it is uncharged and non polar in nature

c) Phosphate group (with alcohol) – It is hydrophilic as it is negatively charged and polar in nature.  

When the phospholipids are placed in  water, the molecule rearranges itself in a way that the hydrophobic head face inside and the hydrophilic head face outside thereby forming micelles.

Hence, option 1 is correct

Which is an extreme disturbance to any ecosystem ​
adelina 88 [10]
Extreme disturbances are complex events. The terminology used to identify them, such as 'hurricanes,' 'fires,' 'economic collapse,' 'war,' or 'drought,' is insufficient for advancing understanding about how they interact with, and affect, ecosystems, including SETS.
