4 0

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.

Archy [21]

Answer:

13.64%

Explanation:

In this question, we apply the Capital Asset Pricing Model (CAPM) formula which is shown below

Expected rate of return = Risk-free rate of return + Beta × (Market rate of return - Risk-free rate of return)

= 4.8% + 1.7 × (10% - 4.8%)

= 4.8% + 1.7 × 5.2%

= 4.8% + 8.84%

= 13.64%

The (Market rate of return - Risk-free rate of return)  is also called market risk premium

Crusher Company has provided the following data for maintenance cost:
Firdavs [7]

Answer:

Total Fixed Cost: $13,020

Explanation:

Fixed cost is calculated using high low method.

High low method seeks to find variable cost per hour / unit by dividing the difference of cost (total cost at two levels) with difference of activity level. Than variable cost is reduced from total cost to identify the fixed cost. Below is the calculation:

Current year cost: $ 37,850        Current year machine hours: 19,100

Prior year cost:      $ 33,300        Prior year machine hours:     15,600

Variable cost per machine hour = <u>Current year cost - Prior year cost</u>

                                      Current year machine hour - prior year machine hour

Variable cost per machine hour: <u>37,850 - 33,300</u> = $1.30 per machine hour

                                                       19,100 - 15,600

Variable cost current year: ($1.30 * 19,100) = $24,830

Variable cost prior year: ($1.30 * 15,600) = $20,280

Fixed cost: Total cost - variable cost

Fixed cost current year: 37,850 - 24,830 = $13,020

Fixed cost prior year:     33,300 - 20,280 = $13,020
