Hello. This question is incomplete. The complete question is:

"Which of the following best describes the long-term impact of using a nonrenewable energy source?

A: Geothermal energy can disrupt the water table and harm water supplies.  B: Nuclear power damages the atmosphere by producing air pollution.  C: Burning biomass to produce energy releases greenhouse gases.  D: Coal mining can pollute water supplies and kill fish and aquatic plants."

Answer:

D: Coal mining can pollute water supplies and kill fish and aquatic plants.

Explanation:

The use of non-renewable energy has proven to be a strong pollutant of ecosystems and biomes. Coal mining is an example of how the use of non-renewable energy degrades nature.

The environmental impacts of mining are diverse and varying in scale: from specific local problems to major biological, geomorphological, water and atmospheric changes. Therefore, knowing these problems and minimizing their effects is of great necessity to ensure the preservation of natural environments.

Coal mining can pollute the water supply and kill fish and aquatic plants. Not to mention the degradation of soil and vegetation that this activity promotes.

That is the opbposite of synthesois reaction
yaroslaw [1]

The two basic reaction types are synthesis and decomposition. ... Decomposition reactions are the opposite of synthesis reactions because they take apart larger molecules and/or compounds. The generic equation for a synthesis reaction is A + B à AB, where A and B are the pieces that make up the compound/molecule AB.

6. A scientist measures the circumference of acorns in a population of oak trees
melisa1 [442]

Answer:

6. 2 cm

8. Greater than 2 cm and less than 2 cm

Explanation:

Complete Question

6. A scientist measures the circumference of acorns in a population of oak trees and discovers that the most common circumference is 2 cm. What would you expect the most common circumference(s) to be after 10 generations of stabilizing selection?

-2 cm

-Greater than 2 cm or less than 2 cm

-Greater than 2 cm and less than 2 cm

-Can't tell from the information given

8. Refer to question 6, but this time answer what you would expect after 10

generations of directional selection.

-2 cm

-Greater than 2 cm or less than 2 cm

-Greater than 2 cm and less than 2 cm

-Can't tell from the information given

Solution -

6. In an stabilizing selection, the average trait of a given population is favored over extreme values. Hence, it can be said that one specific trait is over presented in a given population. For example – uniform human birth weight, number of eggs a bird lay etc.  

Here in this case if most common circumference is 2 cm , then the tree population will try to have this trait as a stabilizing trait.  

Thus, option A is correct

8. In a  directional selection, the genetic variation decreases as per the environmental change. And hence the average trait will not be selected. Instead traits either higher or lower the average values will be preferred.  

Thus, option C is correct
