1. Hydroelectric power can come from energy carried by ocean waves, tides, salinity, and ocean temperature differences. This energy can be harnessed to generate electricity. Figure 1—Tidal Turbine (attached below)

a. Reference Figure 1 to answer the following:

i. Explain how tidal turbines can create electrical energy to power homes.

ii. Describe one effect the tidal turbine may have on the ocean environment.

iii. Describe one possible impact tidal turbines can have on the biodiversity of ecosystems.

i. Propose a strategy to avoid the impact described in (iii). Justify your solution by explaining a potential advantage.

b. Ocean energy has the potential of providing a large amount of renewable energy around the world. Explain the advantage of using this renewable energy source over other renewable energy options.

c. Globally, an estimated 1,800 TWh of tidal energy exists per year. There are several tidal power plants around the world, including large ones in South Korea, France, and Canada. The largest tidal plant produces 0.5 TWh/year, which can power 46,000 homes annually.

i. Calculate the number of homes that can be powered by 50 TWh of energy.

ii. Calculate the number of tidal plants needed to power 92,000 homes annually.

the correct answer is option c. elenita versus "early puerto rican decor" is the best example, out of all the options, of a cultural conflict. a cultural conflict is defined as what happens when different cultures, that have different values and believes, clash. elenita not liking or accepting the puerto rican style of decoration, would represent that she does not identify herself with the puerto rican culture, therefore does not want to have decorations influenced by that culture.

marginal cost is a microeconomic measure that us to evaluate the extent to which the level of production of a good is sustainable in accounting, that is, to how many quantities the company plans to profit from the production of the good.

the concept of marginal cost is simple, it means the cost of producing one more item. for example, in the case of pies, the marginal cost is the cost of producing one more pie than those that have already been produced.

it is important to understand that productive activity influences marginal cost. the marginal cost of some goods can be very high, while others may be insignificant. for example, the marginal cost of producing an extra plane is very high. already the marginal cost of a water company to provide 1l more water is derisory.

in the case of pies, the cost involves the inputs, the labor and the fixed cost, which involves the fixed space of the bakery. the level of production initially has the marginal cost decreasing because there is space and manpower available. however, to produce more you have to hire more workers and buy more inputs. if physical space is limited, workers will conflict with places, inputs and their productivity will decrease, meaning there is an optimum point of production for each level of space and manpower. from this point on, the productivity of the workers will be getting smaller because of lack of space, so that the marginal cost of producing one more pie will be increasing. so, although you have not posted the chart, but if you have the answer, you can see that my explanation goes according to the marginal cost curve that will increase from the 4th pie, answer (c).
