Cardiovascular disease can affect both the heart and blood vessels and the most common sign is chest pain. It is the leading cause of death in the United States with it being responsible for one in every four deaths. Quitting smoking will improve the health of the heart and blood vessels as well as greatly reducing the risk of recurrent heat attack and cardiovascular death.
Answer:
The coastal ocean seems to be more productive than the waters of the similar height in the open ocean due to ample availability of water, sunlight, and nutrients. The coastal ocean has more nutrients due to the process of upwelling, that is, movement of water offshore by the currents.
Also, water situated on the continental shelves is comparatively shallower and thus it is turbulent. This mixing or turbulence keeps settling the nutrients stirred up and accessible, and eventually, ample of nutrients erode off the continents themselves and so water nearby to the shore seems to be greater in nutrients.
On the other hand, in the surface water away from the coastlines, usually, there is a lot of sunlight but no availability of adequate nutrients. Therefore, the majority of the ocean surface is not much productive.
Explanation:
1. Air pollution would still be an issue since fossil fuel trucks that produce exhaust have to go pick up recyclable items and bring them back. Also, the recycling process itself produces a lot of pollutants from inside the factory.
2. Contamination is also a huge obstacle in the recycling industry. Sometimes there are errors with sorting through recyclable stuff and let's say, for example, a spray can gets mixed in with other types of recyclables; it can contaminate the new products.
3. Most plastics can not be recycled. There are about seven types of plastic that we find and encounter on a day to day life, but only two of those plastics are recyclable. What isn't recyclable will be collected, processed, sorted and then thrown into a landfill.
Hope this helps.
Since you provide no options, here are the usual parts of scientific method :
- Idea / question which answer you want to find out
- Research , collecting all kinds of data
- Hypothesis , an explanation that is made at the starting point, before the experiment
- Experiment , to find out whether your hypothesis is right
- Analyze the data that you got from the experiment
- Conclusion, your final judgement based on the result of your experiment
