Answer:
Consider the following information for three stocks, A, B, and C. The stocks' returns are positively but not perfectly positively correlated with one another, i.e., the correlations are all between 0 and 1. Expected Standard Stock Return Deviation Beta
A 10% 20% 1.0
B 10% 10% 1.0
C 12% 12%1.4
Portfolio AB has half of its funds invested in Stock A and half in Stock B. Portfolio ABC has one third of its funds invested in each of the three stocks. The risk-free rate is 5%, and the market is in equilibrium, so required returns equal expected returns. Which of the following statements is CORRECT?
Question 13 options:
a) Portfolio ABC's expected return is 10.66667% correct answer
. b) Portfolio AB has a standard deviation of 20%.
c)Portfolio ABC has a standard deviation of 20%.
d)Portfolio AB's required return is greater than the required return on Stock A.
e)Portfolio AB's coefficient of variation is greater than 2.0

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.
