Scientists are closely monitoring caribou populations to examine the effect of global climate change on
habitat. The maximum population size for a herd of caribou based on the amount of habitat was 500,000. A
herd of caribou currently has a population size of 198,000 caribou as a result of habitat loss. Which of the
following methods should be used to determine the percent change between the maximum population and
the current population for this herd of caribou?

Answers

Answer 1

Answer: (198,000 caribou - 500,000 caribou) / 500,000 x 100

Explanation: makes sense for the math

Answer 2

The percentage difference allows testing the hypothesis. The decrease of 60.4% of the herd is due to the decrease of the habitat.

To test the scientists' hypothesis between the size of the caribou population and the size of the habitat, they must use a statistical method.

The percentage difference is a method that shows the difference between the current values ​​and some reference ones, it allows knowing the magnitude of the change between the two values, its expression is

            D% =[tex]\frac{measured \ value - reference \ value }{reference \ value } \ 100%[/tex]

Let's calculate

              D% = [tex]\frac{198000 - 500000 }{ 500000}[/tex]198000 - 500000/500000 100

              D% = -60.4%

The negative sign indicates decrease.

Therefore, the percentage difference allows the hypothesis to be tested. The decrease of 60.4% of the caribu is due to the decrease of the habitat.

Explain each of the five theories of emotion (James-Lange, Cannon-Bard, Schachter-Singer two-factor theory, Zajonc and LeDoux, and Lazarus) discussed in the text.

Answers

Answer:

The James-Lang theory states that our experiences of emotion is our awareness of our physiological responses to emotion-arousing stimuli, meaning that your body does certain thing which is then followed by an emotion. For example, your heart racing, and body shaking would be followed by a sudden rush of fear. 

The Cannon-Bard theory states that an emotion arousing stimulus simultaneously triggers a physiological response and the subjective experience of an emotion. Disagreeing with the James-Lang theory, the Cannon-Bard suggests that the feeling of fear does not cause your heart rate to increase but your heart rate increasing, does not evoke a feeling of fear, rather, these are both separate occurrences that happen simultaneously.

The two-factor theory states that to experience emotion, you must be physically aroused and cognitively label the arousal. This means that in order to feel an emotion you have to be consciously aware of the stimuli provoking and causing the emotion. 

The Zajonc, LeDoux, and Lazarus theory states that some emotions can occur instantly with out conscious appraisal.

Can you describe at least 3 examples of
austerity measures and the political
consequences for members of the British
Parliament

Answers

Answer:

Austerity is a set of political-economic policies that aim to reduce government budget deficits through spending cuts, tax increases, or a combination of both. Austerity measures are often used by governments that find it difficult to borrow or meet their existing obligations to pay back loans. The measures are meant to reduce the budget deficit by bringing government revenues closer to expenditures. This reduces the amount of borrowing required and may also demonstrate a government's fiscal discipline to creditors and credit rating agencies and make borrowing easier or cheaper as a result.
