The correct answer is Gabriela Mistral and Pablo Neruda.
Moderate levels of disturbance refers to the factors which results in an increase in community diversity, which is based on the intermediate disturbance hypothesis.
<h3>What is Intermediate disturbance hypothesis?</h3>
This states that local diversity is maximized when the ecological disturbance of a given area is intermediate. Diversity on the other hand refers to the number of species present in an area over a given period of time.
The disturbance being too high or low will lead to adverse effects on the species which is why an intermediate effect will lead to an increase in the diversity of the species which are present in a given area. This is therefore the reason why it was chosen as the most appropriate choice.

Answer:
convergent evolution is the correct answer.
Explanation:
Assuming no other variable costs, the marginal cost of a taco is; $5
Formula for marginal cost is;
Marginal cost = change in cost/change in quantity
We are told the cost of hiring an additional worker is $200.
Thus; change in production cost = $200
We are told that the marginal productivity is 40 tacos. This marginal productivity of the change is cost is the change in quantity.
Thus;
Change in quantity = 40
Finally,
marginal cost = $200/40
Marginal cost = $5

42 cards is after his dog ate half, so before that would be 42 * 2 = 84.
Even before that, he bought 5 new baseball cards, so add that to the 84 cards and you have 84 + 5 = 89.
Fred started out with 89 baseball cards.
