Answer:
the engineer needs to consider alternatives for all of the areas of the design process that are considered costs
Explanation:
In order to accomplish this, the engineer needs to consider alternatives for all of the areas of the design process that are considered costs. This includes materials, marketing, manufacturing, etc. Many times the material that is being used alone can skyrocket the cost of making a specific product. Therefore changing to a new material may lack some of the wanted benefits but will reduce the overall cost. Manufacturing techniques can also drastically reduce costs by simplifying the process you save on electricity costs and worker wages, while still outputting the same amount of product, which in term reduces the overall costs of the item.
The contractile vacuole expels water out of the cell by contrasting.
Arteries are generally larger, undergo more blood flow, and exhibit more blood pressure.
Veins are smaller than arteries, and can have valves in certain parts of the body.
Answer:
Explanation:
Tidal power can be harnesed and be used to drive turbines which are used in hydroelectric power stations. Tide involves the movement of water from one place to another and this results in ocean currents. The tides carry a huge amount of renewable energy in them.
Wave power: waves accompany tides. These waves can be easily harnessed to drive wind turbines which in turn produces electricity. They can also be used in wind mills.
Power from fossil fuels: Oceans contain a vast reserve of fossil fuels. Most oceans in times past are sedimentary basins that accumulates remain of organisms. As natural processes plays out, they yield fossil fuels. These fossil fuels can be tapped for use in different machines and gas power plants.
