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.

Answer:

<u>Interlocking corporate director</u>

Explanation:

Interlocking corporate director refers to an individual serving as a director on the board of multiple companies.

Interlocking directorship is not considered illegal if the companies of which the same individual serves as a director, are not competing firms.

In the given case, an individual serves on the board of a bank, also serves the board of a computer manufacturing company that usually borrows from the bank.

Here, the independence and objectivity of the director would be impaired and this may lead to a situation of conflict of interests as the director exercises sizable influence in framing the lending policies of the bank.

Thus, such a situation would be in violation and the director may have to step down from the board of one of the companies.

You are considering a 10-year, $1,000 par value bond. Its coupon rate is 8%, and interest is paid semiannually. If you require a
Schach [20]

Answer:

$1,061.28

Explanation:

We need to calculate the present value of the bond using the minimum effective rate of 7.1225%

First we calcualte the present value of an annuity of $80 for 10 years

C * \frac{1-(1+r)^{-time} }{rate} = PV\\

80 * \frac{1-(1+7.1225%)^{-10} }{7.1225%} = PV\\

PV = $558.72

Then we calculate the $1,000 in 10 years present value

\frac{Principal}{(1 + rate)^{time}}= PV

\frac{1,000}{(1 + 7.1225%)^{10} } = PV

PV =  $502.57

Then we add both values

$502.57 + $558.72 = $1,061.28

This will be the present value AKA market price which yields the minimun rate of 7.1225%
