According to E. Mavis Hetherington's research, Barney would most likely be categorized as a(n)
A) defeated
B) competent loner
C) enhancer
D) good-enough
The answer to this question is A) defeated
Explanation:
E. Mavis Hetherington is an important Canadian psychologist mainly known for studying divorce and the effects of it. About this, the psychologist proposed divorce is a complex process and has a great impact on those involved. In the case of the spouses, E. Mavis Hetherington proposes four main styles spouses might acquire after divorces such as competent loner, defeated, enhancer, etc.
In the category of defeated this psychologist includes those that do not cope with life after divorce, instead, they experience depression, loneliness, regrets, and other negative feelings, which stop them from thinking positively about the future or adapting to their situation. This category describes Barney because after divorce he feels regretful and depressed; also, he has great difficulty to cope with life or adapt to the situation.
Since, the options have not been given the question is incomplete. The complete question is as follows:
The island of Guam traditionally has not had any snakes that prey on birds; however, brown tree snakes that prey upon birds were introduced. Use your knowledge of wolf-moose population dynamics to determine what happened to the population dynamics of birds and the new snakes on Guam. Which statement is probably one of the results of the snake introduction?
Because prey was abundant and few predators existed, snakes spread throughout the island.; Snake populations increased exponentially as they preyed upon birds that had no defenses against the predators.; As snake populations became very large, they reached the carrying capacity of Guam and caused bird populations to crash.; Because bird populations crashed, one of the birds' main prey items, spiders, increased their population size.
Answer: Because bird populations crashed, one of the birds' main prey items, spiders, increased their population size.
Explanation:
The wolf-moose population dynamics suggests that if the population of the moose increases the wolves will get more food and will increase in number whereas if the population of moose decrease the wolves will also decrease. This describes the predator-prey relationship.
According to the given situation, all the statements describes the predator prey relationship between birds and snake. The snake population will increase in the Island due to the availability of birds as food. But the statement, Because bird populations crashed, one of the birds' main prey items, spiders, increased their population size. is not directly related to the predator prey relationship between bird and snake. This is one of the consequences of the decline or crash of the bird population after the introduction of the snake population.
