Please help ASAP please, I can't answer these question. 3 benefits that will occur if Sea walnuta is removed.

1. There will be no High Cost of construction and maintenance.

2. Some designs of these sea walls might be unattractive.

3. natural processes can take place ... for eg. habitat migration. 

well first you need the sample of the temperature and gas level. i couldnt write a hypothesis unless i had some data. i think temperature changes will effect volumes of gas because gas changed into a solid or liquid at specific temperatures.
