Why do you think DNA evidence is the best evidence for determining how closely related organisms are?

Answers

because it hdherhrheh

Answer:

DNA evidence can show the evolution patterns of organisms, the relationships among species, and how evolution occurs. Because of this, DNA evidence can show how closely related organisms are by comparing DNA and genetic codes to show their shared ancestry and how they evolved.

3. How do gases from the air help break down rocks?

4. How does erosion make more soil? *

5. Explain how erosion can be helpful to the environment. *

6. Explain how erosion can be harmful to the environment. *

Answers

Answer:

3) Chemical weathering changes the molecular structure of rocks and soil. For instance, carbon dioxide from the air or soil sometimes combines with water in a process called carbonation. This produces a weak acid, called carbonic acid, that can dissolve rock.

4) Soil erosion is a gradual process that occurs when the impact of water or wind detaches and removes soil particles, causing the soil to deteriorate. The impact of soil erosion on water quality becomes significant, particularly as soil surface runoff. Sediment production and soil erosion are closely related.

5) Natural soil erosion can play a beneficial role in the environment too. ... The erosion also helped cleanse the soil of any useless materials, such as rotting tree matter or nutrient-less dirt from the area. The replaced soil can often become nutrient-rich and help plant life thrive.

6) The effects of soil erosion go beyond the loss of fertile land. It has led to increased pollution and sedimentation in streams and rivers, clogging these waterways and causing declines in fish and other species. And degraded lands are also often less able to hold onto water, which can worsen flooding.
