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.

Deffense [45]

Answer:

Dr Allowances for sales returns     $600

Cr Sales refund payable                             $600

Being increase sales refund estimate

The necessary entries required for the sales refund payable is shown below:

Dr Allowances for sales returns     $600

Cr Sales refund payable                             $600

Anthony currently earns $25 an hour and works 40 hours a week. When his boss offers to pay him $29 per hour, Anthony decides to
timofeeve [1]

Answer:

substitution and income effects will counteract each other totally

Explanation:

A labor supply curve is an economic analysis tool that shows the number or workers that are available to work or that can work at various wage rates.

The labor supply curve can either be bending backwards or sloping downwards or upward curving but it shows the relationship between labour and wage rates.

A labor supply curve can be affected by factors such as population, changes in social behaviour, opportunities in other markets, among other things.

From the above question, it is seen that a change in wage rate for Anthony from $25 to $29 does not affect his work hours positively of negatively. His work hours is the same despite the increase in hourly wage.

The effect of the Anthony sticking to 40 hours of work despite an increase in wage, which could have served as some motivation for him to put in more hours is his labor curve remains same. An increase in wage has done noting to affect the number of hours he works and as such his income vs work rate counters each other.

Cheers.
