Answer:
The options are given below:
A) competitively exclude other predators.
B) prey on the community's dominant species.
C) allow immigration of other predators.
D) reduce the number of disruptions in the community.
E) prey only on the least abundant species in the community.
the correct option is B
Explanation:
Keystone species refers to a predator which prevents a particular herbivorous species from wiping out the dominant plant species. If the number of prey are low, the keystone predators can be less abundant and still be effective. Keystone species have a disproportionately large effect on its environment relative to its abundance.
Therefore, by preying on a community's dominant species, keystone predators help to maintain the species diversity in the community, because they ensure that the dominant predators do not totally wipe out the various organisms present in the ecosystem.

Answer:
D. international diversification
Explanation:
The Multinational corporations can reduce their risk by international diversification and reduced risk can increase debt capacity of MNC. The higher capacity to meet scheduled debt payment also reduces cost of capital.
The effect of international diversification on capital structure can be explained through
1. Co-insurance effect: Combining businesses with international firms provides reduction in operating risk and thereby increase debt capacity. This helps MNCs to include more debts in their capital structure.
2. Transaction cost theory. Internationalization is a way of internatilize intangible assets. Since intangible assets are not difficult to sale , international diversification helps MNCs to exploit their intangible assets. So MNCs with an eye of international diversification will try to develop these type of assets in their asset base.
3.Agency cost argument: MNCs will have high agency costs Diversification helps to reduce these agency costs International diversification creates larger markets and generates growth opportunities. Growth opportunities and debt ratios are inversely proportional .MNCs with higher growth opportunities will rely on equity rather than debt.

The amounts that are relevant for the selection of one contract over another are:
a) Contract revenue and labor costs
Explanation:
a) Data and Calculations:
Contract X Contract Z
Contract Revenue $ 200,000 $ 260,000
Materials 10,000 10,000
Labor 88,000 120,000
Depreciation on Equipment 8,000 10,000
Cost Incurred for Consulting Advice 1,500 1,500
Allocated Portion of Overhead 5,000 3,000
b) The costs of materials and cost incurred for consulting advice, though variable, are equal in each contract. They are not relevant in determining the contract to choose. Contract revenue and labor costs are variable and not equal. They are relevant in determining the contract to select. They make a difference in the decision. Depreciation and overhead costs represent sunk costs. They are not relevant in the decision.
