Solution:
The correct answer is:
Yes, Kudzu helps prevent erosion.
Explanation:
Kudzu is a leafy vine that can prevent soil erosion. This is due to its wide leaves and strong root system that prevents soil erosion. In fact, Kudzu exhibits a symbiotic relationship with nitrogen-fixing bacteria, which may help explain their successful growth on heavily eroded sites. The kudzu cover prevents soil erosion because produces a high density of organic matter and this slows down the speed of rainwater. Also, Kudzu maintains soil moisture and prevents runoff even on steep slopes.
Answer: B
Explanation: The other answers are talking about similarities among different species.
Answer:
C. Larger compounds break down into two or more smaller compounds.
Explanation:
During a decomposition reaction, the bonds between the atoms break down in the starting substance. The atoms then rearrange to form new bonds, resulting in new substances with properties different from the starting material.
<span>The correct answer is b. Option a is incorrect because these models can demonstrate scientific theories, but they don't prove scientific theories (you would need experiments for that). Option c is incorrect because the models aren't always representing something abstract (i.e. DNA is very real, just very small). Option d is incorrect because they don't precisely mimic something in nature, but instead help us visualize something in nature that is difficult to see or comprehend.</span>
