Two or more related lineages acquire a similar characteristic which is not found in a common ancestor. What are the structures c
motikmotik

Answer:

The correct option is D. analogous

Explanation:

We speak of an analogy when one structure is similar to another or has the same function, but whose embryonic development and its origin or ancestor is not common, they are different, in other words, they are analogous structures if they fulfill functions or acquire similar characteristics starting from the same medium, without requiring them to have the same evolutionary origin (they may or may not be similar structurally and embryologically).

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.
