Many mutations that occur will spread quickly throughout a population, creating new species.
Answer:
Primary succession.
Explanation:
Ecological succession refers to the changes involved in the species structure of a community that is established in a particular habitat over time. The succession is of two types: the primary succession and secondary succession.
When the succession takes place on the barren land then succession is considered primary succession.
In the given question, the moss invades and colonizes the rocks and breaks them into the soil. Here the moss species is known as the pioneer species and since the moss grows on the barren rock, therefore, is considered the primary succession.
Thus, primary succession is correct.
<u>Answer:</u>
A solution that can help to reduce noise pollution caused by things such as pile-driving is air-bubble curtain.
<u>Explanation:</u>
- The noise pollution caused by things such as pile-driven into the soil is very high.
- There are many solutions to reduce this noise pollution, air-bubble curtain is one of the useful and simplest solution to reduce noise pollution.
- This solution is based on dynamic sub-structuring technique and modal decomposition method.
- The major drawback of this solution is sound absorption becomes critical, when this method is employed in smaller piles it is because of the radiated acoustic energy is concentrated at higher frequencies than the resonance frequency of the air bubble.
Answer:
The second one
Explanation:
Polar molecules have an even charge, like water, while non-polar molecules have uneven charge, like oil
